Printer Default

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

Maybe check your printer software for configuration.

Hi Andrew, Firefox typically sticks with the last printer you used, so if you find that you need to keep changing this, perhaps it's a setting. To check on that:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(2) In the search box in the page, type or paste print_printer and pause while the list is filtered -- this preference should list the name of the last-used printer. Is it stuck on the nonexistent printer? Does it show a "lock" icon?

Assuming that preference is not locked:

(3) In the search box in the page, type or paste print.save_print_settings and pause while the list is filtered. If the preference is bolded and has a value of false, double-click it (or click the Toggle button or Reset button at the right end of the row) to restore the default value of true

Anything unusual there?

Thanks for this - worked perfectly. Incidentally, the 'Mark it a solved' in the email tool me to:
