How do I completely remove an HP printer software?

i have an older model HP printer, and it seems to be having problems with the new operating system, Catalina. It does have an uninstaller, but I have kept getting error messages that a file will corrupt my iMac computer. I've deleted any HP files that seem to be a problem, but somehow I seem to have deleted the uninstaller or it does not seem to work. I am left with what seems like a huge number of files associated with the HP Photosmart 6520 printer I've got. I do feel the files still in the computer are causing problems. Any advice on how to remove the offensive files? I also don't want to delete any files that are not HP, and sometimes it is difficult to determine which is which. I want to completely remove all the files of my HP printer, so as to not have to worry about malware or corrupted files.


I appreciate any help with this...

iMac 21.5″, macOS 10.15

Before you do that check Software Update. HP released updated drivers today that allegedly address those nagging messages: How to update the software on your Mac


Your HP Photosmart 6520 is an AirPrint-enabled printer. No drivers are required, no drivers need to be updated, and no nagging messages will appear if you install it as an AirPrint printer.


Refer to this excerpt from The Register:


"The Register understands from sources familiar with the matter that HP Inc asked Apple to revoke its printer driver code-signing certificates. It appears this request backfired as it left users unable to print. A HP Inc spokesperson told us on Friday night:

We unintentionally revoked credentials on some older versions of Mac drivers. This caused a temporary disruption for those customers and we are working with Apple to restore the drivers. In the meantime, we recommend users experiencing this problem to uninstall the HP driver and use the native AirPrint driver to print to their printer."


I don't have any HP printers but it seems to me that if HP is recommending macOS's native AirPrint driver, then you should take their advice.


Apple agrees with them. Excerpted from Add a printer on Mac:


"Don’t install the software that came with the printer or from the manufacturer’s website; follow the instructions in one of the tasks below, ..."


... and


"If you have an AirPrint printer, you don’t need to check for software updates."


Anyway, if you run into trouble getting rid of HP's driver software as HP recommends, please write back and I will attempt to help. I can't guarantee success because I gave up on HP a long time ago for reasons such as this.
