Linux – How to set default “Page Setup →Page Size” as A4 in Firefox

firefoxlinuxprinting

In my Firefox (linux) I can change the page as A4 in File → Page Setup → Page Size. Doing this, I inform the browser to print my pages as A4, instead of the default of Letter. My printer doesn't have Letter paper size (it just exists in USA). If it forget to change the page size, I have to walk to it, press "change page size" to start printing it.

How do I set the default page size to A4 once and forever?

I had this same issue today and found this post after searching Google. I fixed it in basically the same way as Android Eve laid out, just using the print.print_paper_name setting instead and using iso_a4 as the value.

So the long version, that's:

  1. In the address bar, type about:config.
  2. Enter print.print_paper_name in the filter box and press Enter.
  3. Double-click the entry named print.print_paper_name.
  4. Enter iso_a4 in the dialog box and press OK.
  5. Notice that it now works fine, and upvote this response ;)
