21.4 update lost printing functionality, how can I revert back to previous version?

printer outputs a blank page 11x17 but "letter" prints fine. BB print function will not print a custom page range. please give me back the previous version.

Printer is HP MFP E786. I up dated drivers, no success.

IF you saved the previous installer, delete and reinstall.

IF you deleted the previous installer, try restoring from Windows File Explorer "previous versions" in the app's file properties.

IF neither of these approaches works, idunno….🤨
