Pixma Pro 100 not printing borderless on Mac (Sonoma)

[2CrowsJoy]

I'm having a problem on a Pixma Pro 100. After installing Canon IJ printer with the CUPS driver downloaded I can now see the borderless capability but I can't adjust the amount of image extension. The slider is greyed out. I can still access everything I need with the old PC laptop...

Check that the installed printer is the Canon IJ Series driver and not the AirPrint driver.

Also be sure that you are selecting a paper size that allows borderless printing.
