After I print a page, Firefox seems to remember most of the options I chose for next time.

For example, if I print using some custom margins, Firefox will default to those same custom margins the next time I print a page. The same for duplex options - Firefox remembers that I want to print double-sided and with "Flip on short edge".

However, it doesn't remember my "pages per sheet" settings. It's annoying because I always print 2 pages per sheet, but Firefox defaults to 1. So I need to change that setting to 2 every time I print. If I forget, I wastefully use twice as much paper.

I've checked in about:config and `print.save_print_settings` is set to `true`. Like I say, most of my settings do get saved, but not "pages per sheet".

Is there anything I can do to set a persistent preference for this?

Hello, After Firefox removed about:config option from Beta and Nightly, can you tell me how to remove Header and Footer when I print documents? I don't want to include URL, dates, times etc. but a clean document or file?

How can I customize the headers and footers of a print job? Specifically, I want to change where the header and footer info appear on the page, i.e., left corner, center, right corner. I'm using Firefox Browser version 141.03. Under Print > Options, the only option is to show or not show the headers and footers. There is no option to EDIT them. Thank you.

(April 2025) So suddenly, after my most recent FF update, if I have a document open in FF and hit "print" and choose "use system dialog box" (or whatever the exact wording is), Firefox Print opens up instead of my usual system dialog box. Why is this happening, and is there a setting I can change to DEFAULT to the regular SYSTEM PRINT dialog box instead.

I do not like FF Print. It prints one page at a time w/ like a minute pause between pages in a multi page document. And when I need more settings, it opens up the HP dialog box anyway, so wtf is the point? I just want my system dialog box back where all my print settings are in one place.

Thank you for any help!

Running Linux-Mint on my laptop. Trying to run an epson ET-2400 ink jet Printer. Need Driver for printer. I have seen some information about software that needs to be added to "talk" to the printer but I cannot find it now. Please someone help.

I've seen the other support requests on this from the past. Setting " print.tab_modal.enabled = false " doesn't seem to work now (Firefox for Mac 141.0.3).

Is there any (2025) way to default to "print with system dialog" rather than having to choose the link off of FF's dialog every time? It makes printing to PDF (which is 95% of my "printing" from FF) needlessly tedious.

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.

Hi Win10 PC fully up to date. Changed my printer from a Xerox to an HP laser. In the control panel, set the HP as the default printer. MS Office prints on the HP without prompting. Firefox (134.0.2) always defaults to the Xerox. The HP is available in the drop down box. Restarting the PC or reloading Firefox makes no difference, Firefox always defaults to the (non existent) Xerox. MS Edge defaults to the HP. Any ideas? Regards - Andrew

Hey all, I'm hoping someone can help me. I have found no answers online to date.

I cannot print from the Firefox browser. When I click the print button, my printer spits out a blank page.

I can print from any other browser, Word, Excel, PDF files, anything except for Firefox. This may not be as much of an issue if Firefox wasn't my primary browser, so when I start doing work on it and find I need to print something at the end, it's a problem.

My printer software is up-to-date, I tried resetting the printing preference to default (assuming I did this correctly), and I even uninstalled and re-installed Firefox (which was a disaster). None of this helped.

Is there one of you who may be able to provide me with the help I need?

I appreciate your effort greatly.

HI,

I updated recently the Firefox installation on my Mac to 139.0.1. I noticed that I can no longer print from certain websites using Firefox. One example is from Alaskair, where I tried to print a ticket and it was just sitting there trying. I had no problem printing the same with Safari.

Is this a known problem? Any suggestion (other than just give up on Firefox and use Safari) for what to do about this?

Every time I update Firefox, new bugs cause annoying problems. That's why I usually not updating for a long time.

Thanks.

'Running ver 137 and now cannot print to my system default printer. Tried the Troubleshoot fix and same result - defaults to PDF. Is there any entry in about:config to ensure system printer is selected. I have checked all system settings and brother printer is the default.
