Problems in setting print parameters in about:config

In the setting, the number of copies is not set. Where is it?
print.xxx.print_xxx

Hi @78783718

You’re question should better be asked at https://support.mozilla.org. This forum here is for learners of the MDN Web Docs.

That being said, I think the number of copies is defined by the printer settings of the operating system. I work with Windows and when I set the default number to 5 in the Windows printer settings and open the Firefox print dialog afterwards, I see also “5” there.

See you,
Michael
