How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

You need to ensure your HP printer has enough paper, ink, or toner, and it is not stuck on paper jam. Also, check the status of your printer cartridge and try replacing it with a new one if it is not good enough. In some cases, your HP printer stops printing after you replace its parts.
The printhead could be clogged, and you might need to clean the printhead several times to restore print quality. Use an automated tool from the printer control panel to clean the printhead. On the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon .
Among the more common technical issues that may bring down a printer are disconnected cables, malfunctioning routers, and low ink levels. Moreover, software problems such as interrupted connections or incorrect settings in your system`s drivers can also cause your printer to show up as offline.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

Run HPPSdr.exe from the download location on your computer. Once HP Print and Scan Doctor is open, click Start, and then choose your printer. If your printer is not listed, turn it on and click Retry. If there is a connection problem, follow the instructions in the tool.
The most common ones are empty ink cartridges, improper cartridge installation, and congested nozzles. Driver and software issues can sometimes cause this problem as well.
Reasons why your HP printer has ink but won`t print

This may seem obvious, but it sometimes happens: first make sure your paper tray has paper in it. Misalignment, clogged printheads, faulty data communication or insufficient ink levels can also be sources of the problem.

If your laptop won`t power up, a faulty power supply, failed hardware, or a malfunctioning screen could be to blame [1]. In many cases, you may be able to resolve the problem yourself by ordering replacement parts or adjusting your laptop`s configuration.
Many printer models won`t print if there`s a loose USB connection or if they`re out of ink or paper. Verify your printer`s ink levels, clean the printhead, fill the paper tray, and avoid using substandard paper.
