I don't understand "Can't use 'air' option because I need to print from iMac."

AirPrint works fine from my iMac (which is running Sequoia, but I think also works with Catalina).

Also see: Can't use "air" option because I need to print from iMac.

Which printer? Vendor and full model name, please.
