I have an HP deskjet printer which worked fine for a while, but then suddenly it starts to print numeric codes on the top left of the page. I checked the settings and I couldn't find anything that could have caused it. Is this a hardware problem? Or can this be fixed by a software update?
Numeric codes on prints from HP deskjet printer
I hope I could see a sample of the print output, but I'm thinking it may be similar to that picture below.
So your report revealed that the printing of the random number suddenly appeared. If this is not a hardware issue then it must be a software. It's hard to get out from speculation like I have since I only rely on my imagination of your description.
To check which of these are possible, try installing the printer to another computer and see if the errors will be repeated during the printing. If there are no similar observations, then the printer is okay and you need to check your computer or reinstall the printer; otherwise, the problem is most likely in the printer.
If the printer was reinstalled and the problem recurred, then the problem is most likely due to a software conflict. This may call for reinstalling the operating system and ensure that it is secured by an anti-virus software.

I hope this could help you.
