Upgraded my 2 machines to Sequoia 15 and consequently I am unable to print or scan with both machines.
A 3rd machine which is not upgraded as yet is unaffected. AirPrint from iPhones is not affected.
The printing process executes without error. The printer receives the job but does not actually execute the print. The machine behaves like the job in the queue is completed normally. No error message. Just no physical printout.
Happens with all applications.
When Scanning - fails to connect to device to enable scanning. error message after some time is attached
