Resolved Canon MX920 Series Print Driver Missing Letter Borderless Page size

[getrealbro]

I recently did a fresh install of Mojave 10.14.6 on my new 2018 Mac Mini. During the setup I accepted the Canon 920 series printer driver that was offered by System Preferences. Everything looked pretty good until I tried to print a letter size borderless document — the PageSetup and Print dialogs didn’t list that size as an option. In fact they didn’t list a lot of page sizes that are available on my other Macs running Mojave 10.14.6.

After some investigation/comparison I realized that the cups Postscript Printer Description file in the fresh install was missing the info describing the missing page sizes. So i reset the Printing System by right clicking the Canon MX920 series in System Prefs>Printers & Scanners. Then I installed the MX920 series drivers using the driver file downloaded from the Canon site.

Here are the tell tale lines from the two .ppd files…
