Welcome to the HP Forums :) I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post that you're having issues with print quality while printing from your HP DeskJet 2630 printer. Don't worry we'll work together to help you find a solution.
To provide you with an accurate solution, I'll need a few more details
Have you recently made any changes before the issue started?
Are you using genuine HP Ink cartridges or refilled ink cartridges?
Have you tried to update the printer firmware?
What happens when you try to print the print quality diagnostic report from the printer?
Let's start off by updating the printer firmware. If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Once done, restart the printer.
For more details on how to update, please use this link: HP Printers - Updating or Upgrading Printer Firmware
If the issue persists, I would suggest here is to do a hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.
With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
Remove USB cable, if present.
Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.
Turn on the printer and wait till warm-up period finishes and the printer is idle.
Next thing, I would suggest here is to print the print quality diagnostic report from the printer.
