Canon imageclass printer not shown in add printer on Macbook Air
We have two Mac computers and one new Canon ImageCLASS MF453dw laser printer. One Mac is a new Mac Mini and the other is last year's MacBook Air. Both are running OS 12.6. I had no problem connecting the printer to the Mac Mini, but the printer does not appear on the list when you try to add a printer using the printers/scanners module in System Preferences. We have tried resetting the printer which eliminates any printers already on the list. Still nothing appears. We use a WiFi network with a Motorola modem/router.
I need a plan for how to diagnose what is going wrong. The printer is obviously on the WiFi network since we can print from the Mac Mini. So why is the same printer not showing up on the list of printers when you ask to add a printer in system preferences on the MacBook Air?
