How do I set Firefox's default printer?

I have these printers.

"HP LaserJet M109-M112" (the Windows default) "HP LaserJet 1020"

Regardless of the value of print.sav_print_settings, the first print dialog after starting Firefox shows "HP LaserJet 1020".

If I manually put "HP LaserJet M109-M112" (no quotes) in print_printer, it reverts to "HP LaserJet 1020" the next time Firefox starts.

How do I make "HP LaserJet M109-M112" Firefox's default? Thanks.

被選擇的解決方法

Problem solved! But first, to answer my last question ... because the printer was specified in user.js.

I vaguely remember doing that (3+ years ago) because Firefox was remembering "Microsoft XPS Document Writer" which I use very seldom; that was annoying me. So I changed the user.js specification.

Is there a way, other than a manual edit, to get/change what's in user.js?

Thanks.

For me, when I click File -> Print, I get a Print Preview dialog with a Destination drop-down on the top-right. Whatever I pick here to print with, it seems to keep whatever I last printed with as the currently selected choice.

Do you see both printers in this drop-down?

Yes, they're both in the dropdown. If I select the desired printer my selection persists until Firefox is terminated. When I start Firefox again it's back to HP LaserJet 1020 (which is not the Windows default printer, and not desired).

Why does Firefox keep using that printer at startup when ...

1. It is not the last printer used 2. It is not the Windows default printer 3. It is not the first (of the two) returned by the EnumPrinters() API
