Hi @Clark_macrogen,

Welcome to the HP Support Community

I understand you are facing an issue with your HP OfficeJet Pro 7720 Wide Format All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• 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 (This is important) 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

Update the printer firmware 

• Click here to download and install the latest printer firmware from your product

If the issue persists, then please follow the steps mentioned in this document: HP Printers - Unexpected Text Prints (Windows)

If the issue persists, then let's try to do a root uninstall and reinstall of the software:

Unplug any USB cable, if any, before doing this.

1.) In Windows, search for and open Programs and features

2.) Select your HP Printer

6.) Open up the run command with the "Windows key + R" key combo.

7.) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”)

8.) Click on the "Drivers" tab

9.) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom

10.) Select Ok

11.) Select Apply and Ok on the Print Server Properties windows

12.) Close Devices and Printers

13.) Open up the run command with the "Windows key + R" key combo

14.) Type c:/programdata and click Ok. Go to Hewlett Packard folder, remove any printer related folders & files.

Hello Andy, 

Thanks for your feedback and the detailed instructions! 

But the firmware is already up to date on the printer as I can see ELLISXLP1N003.2226A.00 on tools

and the latest version available for download is OJP7720_2226A.exe. 

However, I realized that it is only compatible with the old printer driver, which is the HP PCL3 B-size printer class driver, and works well.

I accidentally updated the printer driver to the latest one and the same problem occurs. And later on reverted down and it works fine again...
