Catalina 10.15.17 HP Printers / scanners malware warning then error -21345
After last update Catalina 10.15.7 happen the following with two different printers/scanners HP 5520 and HP 8620, both connected locally by ethernet (different offices/networks without any internal firewall)
1- Try to print: OS give an error of malware of installed HP drivers/app for the printer(s), i think is some to do with the HP certificates have not a valid sign...
1.1- To solve this I have remove the printer and delete the drivers/app then add the printer's. After this all seams to work. I'm able to print, this as happen with the two printers/sanners.
2- Today i've try to scan some documents and give the same error for the two printers/scanners: malware warning...
2.1- Try to use the same recipe of 1.1 (but for the scanner), but in this case don't work.
When i try to open scan, the scanner's give error -21345. Note the print function is working on the two printer...
Any ideas???
