I have a Canon MF8580Cdw.
It is used on a wireless LAN network.
The computer it works with is an iMac.
The scan and print drivers are up to date for Mac OS 10.12.5.
The printer connects to the Lan network, and says "Connected" on its screen.
The computer says the computer is not connected for printing or scanning.
I've reset the modem and router, restarted the computer and printer, all multiple times.
The message "The printer is not connected" keeps showing up.
Can anyone help?
