Ok so I had a problem getting Firefox to scale right when printing. So I followed al sorts of recommendations from Firefox. I can across this one, https://support.mozilla.org/en-US/kb/fix-printing-problems-firefox and when I did this instruction it when from scaling problems to not printing at all.
Reset Firefox printer setting
Several printer issues can be resolved by resetting Firefox’s printer settings:
- Type about:config in the address bar and press Return.
A warning page may appear. Click Accept the Risk and Continue to continue to the about:config page. - In the Search field, type print_printer.
- Click the Delete
button to the right of the print_printer preference.
- Click the Firefox menu at the top of the screen and select Quit Firefox
When you start Firefox again, try printing the page that you had problems with previously.
Note: In older versions of Firefox print.print_printer was the preference name. The old preference name may exist along with the new name. That old preference can be removed by clicking the Delete button. Restart Firefox and print a page after performing the reset. That preference won’t reappear. The newer preference will only be available.
