When I try to print from my iMac, I get an error message "printer not connected to computer".

This has been happening for years but it usually resolves by turning the printer off/on. Have unplugged the printer and shut down/restarted computer. Still not connecting.

Can you tell me how did you connect your printer to iMac?

Customer Replay

Many years ago--don't remember, but probably wireless.

Okay, thank you so much!
Please, provide me with your macOS version.

I think it's High Sierra, 10.13.6
Purchased in 2006?

Do you have access to your printer at the moment?
