I am using LinuxMint 21.3

Print to printer Epson AL-M8100DN does not work.

My printer works. see screenshot

What does that mean?! Can you provide proof the issue? Screenshots and steps to replicate would be nice. What Desktop? X11 or Wayland? Did you try Firefox in Troubleshoot Mode?

Try downloading Firefox from Mozilla, run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

I downloaded Firefox from Mozilla. The same problem arose running firefox-bin. Looks like I have X-11 desktop. " Display: x11 server: X.Org v: 1.21.1.4 driver: X: loaded: modesetting,nvidia

Previously Troubleshooting mode didn't give me any information.

If I save to pdf I can print the pdf file with no problem.
