I have a new HP printer and I am using Firefox from a Windows 10 PC. I am plagued with Paper Mismatch errors when printing emails from Firefox. After a lot of trouble shooting, I have found that this problem seems to be confined to Firefox, as it does not happen when using other browsers, e.g. MS Edge. I have tried resetting all Firefox printer settings and the problem still happens when opening Firefox in Safe Mode.
The print job stops with the error message Paper Size Mismatch after the 1st page, and printing will not continue or even move on to the next job until the error is cancelled from the printer's control panel. This means I have to be working next to the printer and cannot print remotely.
In the printing dialogue box under Printing Preferences, the paper size shows Letter, whereas I am using A4 in the printer, and this is the mismatch causing the problem. I can change the paper size in Printing Preferences from Letter to A4, but I have to do this for every job seperately as the paper size setting always reverts to Letter. This is totally impracticable.
Regretably, I will have to stop using Firefox unless there is a solution. Can anyone help me to change the paper size setting to always default to A4, please? Thanks in anticipation.
