Print ignores default for print to pdf

more options

I have a laser printer set as default on a Windows 10 laptop. In Mozilla, when I select print, that laser printer has the green default check, but Mozilla defaults to Microsoft Print to PDF instead. How can I get Mozilla to accept the default printer without deleting Print to PDF which I do sometimes use but don't want as default? Image attached--it auto-checks PDF but you can see the laser listed above it is the default.

The way this is currently expected to work is that Firefox will default to the last printer you printed to in Firefox (it will not default to the operating system default). So if you print to the laser printer in Firefox then the next time you open the print dialog in Firefox that laser printer should be selected. It sounds like this isn't working for you?

Can you open the page `about:config`, accept the warning, and type 'print_printer'. There should be exactly one preference listed, containing the name of the printer Firefox will choose as the default. What value does that have?

It says Microsoft print to pdf.

I copied the exact name of the laser printer into that field and saved it. Hoping that'll hold once I close the browser...

Yep, that held. Brilliant. Thanks so much!

Glad to hear you've managed to work around your immediate issue. It sounds like Firefox is failing to save the last used printer to that pref automatically though, which is concerning. If you don't mind creating an account on bugzilla.mozilla.org and opening a report there to answer some diagnostic questions that would be very helpful. (If you do, just make sure you have the word "print" in the title and I'll find it.)
