My HP EliteBook laptop and Cannon MX922 are on the same wireless network but I cannot connect to printer. It works with all my other devices so it is specific to this OS. Thank you
Have you installed the linux driver from manufacturer page? MX922 Driver Linux Deb During the installation process you can setup the WLAN settings of the printer.
PS: For installation you may need to install a deb-package manager first.
PPS: This should be a comment, but I do not have enough reputations
