Canon iP90 Ptr outputs blank pgs in 20.04, works in Win10

[Jim]

Ver: Ubuntu 20.04.2 LTS

Expected: CUPS to print to an iP90 inkjet printer.

What happens: Whenever I try to print anything to the iP90, it outputs ~14 blank pages with a ghostly thin line across the top of the page. It hesitates after drawing the sheet of paper into the machine so that's where it's printing that single line (or multiple lines but very tiny), and then spits out the page without printing anything else. That squished line on top is so small, and with the rest of the page blank, I reuse that paper when I leave Ubuntu and boot to Win10. Then I can print to the iP90 all day and the pages come out fine.

What I've tried: I've loaded and deleted the CUPS driver for the iP90 numerous times to no avail. CUPS recognizes the USB printer is attached and it's name & model number.
