hp printer error with Mac
hp envy 7645 was working fine. now an error (yellow triangle with !) appears when I try to print. I have reset, removed printer, used usb, tried AirPrint. Not successful with any method to be able to print. This right before virtual school starts and the kids will need to print. ugh. any suggestions? not sure if this was from the latest macOS catalaine 10.15.6 update or not.
