Uninstalling the Printer Driver
If a printer driver is no longer required, you can uninstall it by following the procedure below.
1.
Open [System Preferences] → click [Print & Fax] or [Print & Scan].
The [Print & Fax] or [Print & Scan] dialog box is displayed.
2.
Select the printer you are using → click the [-] icon.
NOTE
Delete all print queues set from the driver you are deleting.
3.
Delete the folders and files for the driver you are deleting.
[System Volume]/Library/Printers/Canon/CUPSPS2
[System Volume]/Library/LaunchAgents/jp.co.canon.CUPSPS2.BG.plist
[System Volume]/Library/Printers/PPDs/Contents/Resources/CNMC***S2**.ppd.gz
Where *** indicates a character string that represents the printer model, and ** indicates a character string that represents the corresponding language.
IMPORTANT
If you delete a "ppd.gz" file other than that of the printer model you want to delete, the printer driver may not work correctly.
NOTE
If the [Authenticate] dialog box is displayed, enter the administrator's name and password → click [OK].
4.
Restart your computer.
Uninstallation is complete.
