PIXMA MG7520 printing much too small in Chrome on Mac

[doray]

All of a sudden, Chrome pages print at about 1/4 size. This happens on multiple sites.

I'm printing to an older Canon printer (MG7520).

The same pages print properly from Chrome to a new Canon printer, and from Firefox and Safari to the old printer.

I've looked at all the settings under More Settings and tried printing with a custom scale of 100%.

I also cleared Chrome's cache. I restarted Chrome.

I tried deleting and re-adding the printer in System Preferences.

I tried printing in another user's account in Chrome on my Mac. The same thing happens: the printout is about 1/4 of the size it should be.

I deleted my Canon's printer driver, which macOS automatically re-added after I restarted the computer again. No luck.

Any help would be appreciated!
