Check out a list of helpful HP DeskJet 3755 manuals and FAQs written by our printer experts to get you started troubleshooting and getting back to printing. If you are one of those wondering why my HP printer won’t print in black ink, find the best solutions here. Below are some solutions you might want to look into to try and troubleshoot your HP printer.
If you’ve tried the methods below and your HP printer still won’t print, you might want to check for a hardware problem with your HP printer. You may need to update or reinstall the printer driver to fix the HP printer rather than printing problems.
In many cases, the printer does not print, the problem is due to faulty drivers. The printer cannot print for a variety of reasons, from connection problems to faulty configurations or drivers. In some cases, an HP printer stops printing after parts have been replaced.
A frozen print queue may stop working properly and cause printing problems on your HP printer. Many times during the life of an HP printer, jobs sent to print can get stuck in the print queue.
Normally, when you send a print request, Windows sends that print job to what is known as the default printer. When you try to print something, your computer will automatically assign those print jobs to the default printer unless you specifically select a different one.
If your printer is fully connected to the network but is not printing anything, your HP printer may not be set as the default printer in Windows. Now try printing again on the HP printer to see if this is the problem. After the troubleshooting steps above, turn on your hp deskjet 3755 and try to print the page.
Then click the Next button to repair the printout using the troubleshooter. Then click Printer Options and select the Run the troubleshooter option. Then select the “Use the printer” option under the “Troubleshoot” section.
Uninstall and then reinstall the printer using the correct drivers and setup information on this HP website. Click the Update button next to your HP printer to download the latest and correct driver for this device. Here in this step, install the latest drivers for your printer before using it.
If a printer driver is found, it will automatically start downloading the latest printer driver from the official Windows website. The printer driver will automatically check if an updated version is available. Finally, install the latest HP drivers in order to use all printer features.
Now wait a few minutes; The HP printer will automatically connect to the device’s Wi-Fi network. Make sure the printer is connected to a reliable wireless network. Your HP printer is now ready to connect to your wireless network.
Without a network, all mobile devices can be easily connected to the HP Deskjet 3755 printer using HP e-Print, and these devices can be smartphones, tablets, and iPads. Although here in this guide, we will explain all the possible ways to connect HP Deskjet 3755 printer to Wi-Fi for Windows 10 and Mac users. Now turn on all devices such as computers, printers, and wireless routers.
Now restart your computer and connect the printer’s USB cable to your computer. Make sure the printer’s power connection is securely connected to the printer and connect it gracefully. If an HP network printing network cable is connected to the HP printer, make sure the Ethernet cable is secure and check the manual for any blinking lights indicating a network connection.
Find your HP printer in the list of printing devices to see if it is the one you are having problems with. There are some simple HP troubleshooting steps you can take to make sure you can print to your HP printer when it stops working or never works. When you notice that your HP printer stops working, you can run the troubleshooter first. If your HP Envy printer won’t print after a Windows OS update, check out our guide to fix it ASAP.
According to users, most of them experienced this problem after installing new ink cartridges in their HP printers. Many users complain that their HP printers cannot print in black when they have to use the Windows operating system. Most users will probably check their ink levels when the printer stops printing with black ink.
If you are using the wrong size pages, the ink cartridges are clogged, the ink cartridges are empty, there is no communication between the ink cartridges and the printer. To fix this problem, you need to clean the bad cartridges using the printer’s control panel. To resolve this situation, remove the cartridges and reinstall the HP printer properly.
Check the condition of the printer cartridge and try replacing it with a new one if it’s not good enough. New HP printers easily display the ink level or ink problem on the front screen of the HP printer. We hope that after using the latest version of the printer driver, this problem will no longer occur. If you own an hp deskjet 3755 and you have an E3 error on your hp deskjet, this means that the printer has experienced a carriage jam issue.
So, since there is no flat surface (this printer is a microprinter), you obviously think that you will give the printer a page to scan by inserting it into the manual feeder.
Debugging is one of the crucial activity during the software development. It refers to the process of identifying an error in a software application that causes performance issues, then analyzing the issue, and finally resolving it. Debugging allows you to validate your code and fix issues before pushing a software application into the production stage. However, debugging issues are likely to arise during various phases – development, testing, and even production/post-deployment. And, implementing the right debugging tools and methodologies will speed up development and enhance the efficiency of the end-product.
Coming to React Native debugging; the framework is made up of different environments, the most prominent being Android and iOS. As a result, it becomes challenging to debug apps due to multiple platforms involved. Moreover, React Native offers a huge variety of tools for debugging which seems confusing for many, particularly newbies. This post guides you through some effective practices and useful React Native and React debugger tools that will help you to identify issues and fix them like an expert.
React Native Debugging Methodologies and Best Practices
Identifying and Addressing Console Errors, Warnings, and Logs
Console errors and warnings are visible in the form of on-screen notifications with a red or yellow badge.
Errors
Errors will be displayed inside a RedBox with the command console.error(). This RedBox contains a description of the error and also a suggestion on how to resolve the error. Take a look at this example. If you write a style property that the React Native framework doesn’t support, or if you write a property meant to be used for a particular element (like a backroundImage needs to be set for the element View), then the RedBox shows an error along with the list of supported style properties that can be applied to the View.
Warnings
Warnings will be displayed inside a YellowBox with the command console.warn()Such warnings include information on performance-related issues and deprecated code. Most of these warnings indicate some bad practice within your code. Examples of warnings include a notification about the presence of an eventListener that isn’t being removed, the presence of deprecated features and dependencies, etc.
Logs
For issuing logs, either use the command react-native log-android or use the Chrome console with the command console.log(string str)
React Native developers can hide the notifications concerning errors and warnings with the command LogBox.ignoreAllLogs() whenever needed, like during product demos. You can also hide the notifications on the basis of per-log with the command LogBox.ignoreLogs(). This method works in scenarios when a noisy warning cannot be resolved like the ones in a third-party dependency. But, whenever you ignore logs, make sure to create a task for fixing those ignored logs later.
Debugging using React Native’s built-in Debug Mode
Check out how to utilize the built-in debug mode offered by the React Native eco-system employing browsers like Safari or Chrome.
Debugging with Chrome
Install these react-devtools for supporting React Native: Yarn and NPM. Then use the development mode to open the in-app developer menu; here you start the debugging process by activating the debug option.
From the Developer Menu, select the option Debug JS Remotely. This action opens up a channel to a JS debugger. A new tab opens; here, from the Chrome menu, choose Tools – Developer Tools; for opening the devtools.
The other most prominent options to utilize in the in-app developer menu to debug apps are:
Enable Live Reload: for automatically reloading the app, Enable Hot Reloading: for identifying the modifications that result in a changed file, and Start Systrace starts the Android marker-based profiling tool. The option Toggle Inspector helps in toggling an inspector interface. This way, developers can inspect UI elements present on the screen and examine their properties. Then an interface is presented; this interface contains other tabs such as networking for displaying the HTTP calls as well as a performance-related tab. The option Show Perf Monitor tracks your app’s performance.
Debugging with Safari
Your app’s iOS version can be debugged using Safari, and here, you do not have to enable “Debug JS Remotely”. Simply open Preferences and then select the following options:
Preferences
Advanced
Show Develop menu in the menu bar
Next, choose the JSContext of your application:
Develop – Simulator – JSContext
Now, the Web Inspector of Safari is going to open and you would be able to view a Debugger and a Console. And, each time you reload the app, either manually or by using the fast refresh (live reload), a new JSContext will get created. Remember to select the option Automatically Show Web Inspectors for JSContexts; otherwise, the latest JSContext will be selected manually.
Prominent React/React Native Debugger Tools
React DevTools
This set of React tools is employed for debugging the component hierarchy of React and works well for front-end operations. Using this toolset, you can view what’s there deep within your component tree – select the options state of the component and edit the current props.
React Developer Tools are the extension to the browsers Firefox and Chrome. However, to debug apps built in React Native, you need to use an autonomous version of React DevTools and run this command on your terminal – npm install –g react-devtools. Then launch the app by running the command react-devtools; select the option Show Inspector from the in-app developer menu for examining the app’s UI elements.
If Redux is used, then you need to use React DevTools along with ReduxDev Tools to fully understand your component’s state. For this, Redux DevTools need to be separately installed and here, the tool React Native Debugger proves quite useful as well.
React Native Debugger
The React Native Debugger is immensely beneficial if Redux is used during React Native app development. This is a standalone tool that functions on Linux, Windows, and macOS. This tool is used for logging or deleting Async Storage content, detecting as well as diagnosing performance issues, and examining network requests.
The best part is that it integrates React DevTools as well as Redux DevTools within a single app and so, there’s no need for using two separate applications to debug apps for the React and Redux environments. The tool offers interfaces where you can examine and debug React elements and also view Redux logs and the related actions.
React Native debugger outshines Chrome DevTools in employing the toggle inspector for inspecting React Native elements. Besides, React Native debugger provides the functionality for editing styles; this feature is not present in Chrome DevTools.
Flipper
Flipper is a cross-platform tool used to debug JavaScript apps as well as the device and JS logs. It launches simulators for managing devices, can connect with several devices simultaneously to debug apps across multiple platforms, and involves a single-step debugging process including watchpoints and breakpoints.
Flipper edits the components on the fly, then reflects those edits in real-time within the application, and integrates with the app’s Layout Inspector. Its capability of integrated launch management enables developers to define configurations and employ them for unit testing, without having to replicate configurations in several places. Moreover, comes with a plugin-based architecture and myriad handy features; more features are expected in the coming years.
With Flipper, you can view, inspect, and control your apps using a simple desktop interface. Flipper can be used as it is or extended employing the plugin API.

Don’t we all shop from our smartphones? Lately, mobile payments have gained prominence by providing a fast and easy way to make purchases and helping users save time and get an enhanced shopping experience.
How do we make the payment then? Of course, with the help of online payment options using payment gateways. Whether you talk about Retail companies, or you are on e-Commerce stores, freelancing platforms, travel agencies, they all are using payment gateways to help ease your payment.
Based on Statista’s website, by 2023, there will be around 1.31 billion proximity mobile payment transactions by users worldwide.
The payment gateway integration is not subject to one mobile OS; it’s for both Android and iOS. These two OS’s have captured the entire global market, as we all know. Let’s uncover the crucial aspects of integrating payment methods for both Android and iOS.
Let’s start with;
What is a payment gateway?
Payment gateways are the median between online customers and financial institutions. Without intermediaries, in-app purchases and payment processes can’t take place.
As we see, many apps like Amazon, Netflix, etc., ask for a subscription to watch shows, movies, etc. While paying for a subscription, it gets easy as, within a few steps, users can buy the subscription via the third-party app (Google Pay, PayPal).
The funds move through an interbank network, a complex sequence of operations and create risk associated with security assurance. It just takes users a few seconds, but it’s a huge amount of work to deal with underneath the app.
Fortunately, banks take responsibility for all transactions and data safety, but how do you deliver this information to the bank? How will the application know that the customer has funds in his accounts and the account belongs to the customer?
Moreover, what about storing your payment details? What if all this information gets in the hands of the wrong people? Who is responsible for this? Both business owners and mobile app developers should not be the ones to bear this blame.
To get deep insights, let’s now understand how a payment gateway works?
Before opting for payment, users open a cart to buy the items they like. After doing so, they go to payment, wherein you have to enter debit or credit card details.
The information you fill in is sent to a payment gateway system. It then encrypts user data and passes it to a payment processor.
The payment processor is another mediator that begins the transaction process and gets feedback from the bank (Visa or Mastercard).
The processor verifies the data accuracy and then transmits the information to the bank (financial institution), which has to finalize the verification (it takes seconds).
After approval, the amount is withdrawn from the buyer’s card and sent to the merchant’s account.
Why choose payment gateway integration?
Considering the USA market, one can expect the USA Digital payment market to register a CAGR (Compound Annual Growth Rate) of 12.14% over the forecast period from 2022 to 2025 (Source: Statista). Hence, it has become the most important aspect of any business.
The positive thing is that it allows collecting money through the customer’s preferred bank without risking sensitive data.
With the increasing awareness about the ease of online transactions and digital evolvement, consumers are changing their priorities for making payments online. Hence it generates confidence among the users for switching to online transactions, which is why we see the boost in payment gateways.
Here we will see what the trend globally looks like:
In the year 2020, the size of the mobile payment market across the globe was valued at 1.54 trillion USD. This value rose to 1.97 trillion USD in 2021. The market has been predicted to grow at a CAGR of 29.1% from 2021 to 2028 and reach 11.83 trillion USD by 2028.

How to do the integration of payment gateway with iOS and Android?
Install the app or any type of payment gateway based on your needs, such as the size of the business, industry or the targeted country.
One should add client tokens when the server sends a request from your app. It helps generate a new token on every app launch with full authorization and configuration specifics to let the client initialize the SDK. One can execute it using various programming languages like JavaScript, React, NET, PHP, Python etc.
Then the software developers will test the credentials such as customer id, public and private keys etc.
It is important to install additional certifications that accept the PCI-DSS for better security. Further, the Secure Sockets Layer (SSL) guarantees clients’ sensitive information protection.
While processing a transaction, the one-time payment method needs to be configured. It works as: the client sends you card information, the gateways forward it to the server and uses that data to initiate the transaction.
How to know the best applicable payment apps for you?
Firstly, make sure the payment gateway supports your product.
Many payment gateway providers support both digital and physical products. However, not everyone does that, plus some product groups are riskier, so the providers don’t join in.
For example, Stripe has Restricted Businesses, including investment and credit services, gambling, adult content and services, get-rich-quick schemes, and many other categories.
Thus, you must be sure you’re on the “white list” of a particular provider.
Pay attention to pricing
When it comes to payment gateway integration, keep in mind these fee types: monthly fee, gateway setup, merchant account setup, and per-transaction fee.
Dig through gateway documentation to ensure there are no hidden fee charges and the pricing policy is crystal clear.
Check payment methods and card types
You should always list payment tools and services used by your audience and make sure that a payment gateway of your choice supports all of them.
The integration of digital wallet payments differs from payment card support because of different tokenization processes. You must check if a payment gateway allows using mobile wallets.
Another essential point is that if you are targeting the international market, check the cost for businesses and multi-currency payments as some gateways require additional fees.
Study transaction limits
Payment gateways often have limitations for the numbers or amounts of transactions to take place. For example, Square’s maximum transaction is 50,000 USD. This amount is enough for most businesses but may not be the same for you. Anything beyond this limit needs to be split into different instalments.
Look closely at merchant account options
A merchant account is an intermediary account where payments are parked before you get them, a kind of money storage. It is basically for a smooth shopping experience. At times buyers want to return the product or get a refund. To clear such issues easily, one can manage them with the money accumulated in your merchant account.
Well, when we talk about merchant accounts; then there are two types to know about:
First is a dedicated account that is for your business only. It helps you to control your money and operations. Companies with dedicated accounts usually receive faster transactions, but paying a higher price is also necessary to obtain the shortages.
The second is an aggregated account for several merchants (businesses). Mostly, entrepreneurs pick this option as it’s cheaper and easier to set up (it takes less than 24 hours).
The Use Case: Square
Currently, three payment apps mostly applicable for payment gateway integration are Square, Stripe, and PayPal.
Square is the application that provides an all-round top choice for making payments in different ways (online, invoices, in-person, over the phone). It comes with many free features, a powerful POS app, and attractive equipment options.
Square acquired many companies, including Storehouse, Fastbite, and Kili. Major competitors for Square are Google Wallet (GOOGL), Intuit Inc. (INTU), and PayPal-owned (PYPL) Venmo.
Let’s see what Square provided to a company named Kili (developed silicon, electronics, and software that simplify and optimize payment processing) after the acquisition.
While Square already offers a payment option to the users of credit cards via mobile, the Kili acquisition will let the company begin experimenting with Near Field Communication (NFC) payments (like Apple Pay). It will help compete with larger companies by delivering simple and affordable hardware that gives the sellers a safe and smart way to do business.
Conclusion
Does your company deal with any kind of online transaction? You need to allow payments in your mobile app. Using a payment gateway will give you a competitive advantage. The payment gateway is the connecting link between the bank and the customer and removes the hassles associated with safe data storage, transaction security and fraud detection.
Account opening, loan application, mortgage application, credit card application, and others often require proof of address verification alongside customer ID verification. Proof of address verification is an important part of the KYC process and for reducing the instances of financial fraud. An address is an important part of ID verification to verify if a person is who they claim to be.
Not just for verifying customer identity, proof of address via utility bill verification also allows financial institutions to provide services to a specific geographical area. Banks and financial institutions can prevent fines for non-compliance with KYC directives, and also minimize fraud. For example, social networks or neighborhood apps restrict users to resident-only to avoid any type of fraud.
Before digitization became prevalent in the industry, proof of address verification used to be a tedious process that offered poor customer experience, and fraudsters with sophisticated technology could easily fool the manual process. Relying on manual checks for verifying proof of address increases the chances of human errors and creates unnecessary friction and delays for the customers.
For the proof of address verification process, customers must find, scan, and send pages of documents in the required format. The process that should be instantaneous ends up taking days or even weeks, which results in poor customer experience. As there are seemingly endless documents that can be used for proof of address verifications and unique document review standards which can result in multiple failure points. Now that there are instant online proof of address document verification technology available, banks and financial institutions need to find better processes.
What is Proof of Address?
As the term suggests, proof of address is a document that states where a person lives. The address mentioned on the document and the real address should be the same. In financial services, some services are just available to customers living in a specific location, customers living in a high-risk location are generally met with an extreme level of scrutiny. For example, cryptocurrency exchanges in Europe may not want to accept US customers simply to avoid sanctions by the SEC for dealing with unregistered securities.
Restrictions like these can be a regulatory requirement or a company may have set its own policies. Verifying residential information via proof of address documents can help organizations provide services online and comply with regulatory requirements and internal policies.
There are multiple ways to provide location evidence, including a proof of residency letter (Affidavit of Residence), However, the most common way to help prove proof of address is by providing documents that contain address, date of issue, and the customer’s name. Each organization can set its rules on which documents they find acceptable and which they don’t for proof of address verification. Some of the most accepted documents are:
Utility bills
Tax Bill
Bank Statement
Credit card statement
Tenant’s agreement
Employment letter
Common Challenges with Proof of Address Documents
Even with constant improvement in technology, not much has changed in the proof of address verification process. Here are some of the biggest challenges faced by proof of address documents:
Multiple Document Templates
There are thousands of services that can provide a customer with proof of address documents, add various document styles, formats, types of information, and the problem of verifying the document’s authenticity becomes a major challenge in verifying the documents. Based on the use case, there can be hundreds of possible acceptable documents with little to no similarity. It becomes incredibly tough for banks to verify different documents.
Poor Customer Experience
The time consumed in verifying the documents till the account is too much for a customer to ignore. Customers want instant solutions, most people don’t have the time to find the documents, scan them and then wait for days to check if the document is acceptable or not. According to a survey, 50% of customer applications drop off because they were asked to provide proof of ID documents.
The lack of fixed rules and regulations in the financial services industry makes the process confusing for the customers. Additionally, as consumers are becoming familiar with digital technologies, the risk and friction of providing a physical document don’t seem worth the hassle. Even the smallest of errors in a scanned document provided by customers can lead to failure, thus resulting in enhanced poor customer experience.
Cost of Document Handling
Apart from the challenges mentioned above, handing in physical documents and manual verification can cost too much. Approving dozens of applications per month is easy but going through thousands of applications is where the system fails. Banks also have the obligation of maintaining records, and keeping document data safe, which only adds up to the overall cost.
Embedding Technology in Proof of Address Verification Process
One of the best things about technology is that if it’s used in the right sense, it can streamline the most monotonous and tedious tasks. By successfully embedding technologies into the proof of address verification process, banks can speed up onboarding, automate address verification and help in delivering better compliance and fraud prevention outcomes. As with other ID verification methods, you need a combination of different technologies catering to every part of the address verification process.
Online document verification or online proof of address verification technologies should be the first and foremost choice while looking to enhance the proof of address verification process. Online proof of address verification software from DIRO can help businesses in enhancing their verification process, customer onboarding process and improve the detection of fraudulent and forged documents.
