Apple's AirPrint supports your wired/wireless Canon MX922 printer without any Canon drivers installed.
You can control/right-click on your printer entry in System Preferences : Printers & Scanners, and select Reset Print System… from the secondary menu. You will be prompted for your admin password, and then that printer entry will be removed. A subsequent panel will appear showing that your powered, networked printer was discovered by Apple's Bourbon service. Click on that entry, and a re-Add printer panel will appear. By default, it will show your last used Canon printer drivers as a selection, but instead, select Air Print, and then re-add the printer. Once the printer entry is back in the Printers window of the Printers & Scanners panel, again, control/right-click on it to set it as the default printer, and then print something.
