How can I print from the snap packaged version of Firefox?
Same problem here after moving from Firefox 8x to 91.3 ESR (snap) lately. Solved the problem by following this Mozilla help:
Reset Firefox printer settings: http://mzl.la/1BAQqop
- Click on the “hamburger menu” button. (Alternatively, open
about:support.) - Click on “Help” and select “More Troubleshooting Information”.
- On the Troubleshooting Information page, go down to “Printing section”.
- Click on “Clear saved print settings”.
This will remove all modified (incompatible) print settings in Firefox (most likely inherited trough the former profile settings).
Good luck!
