When will the firefox printer settings be fixed to allow multiple printers to be used?
Install two printers. Set one to letter size, the other to 6x4 inches (like a label printer). Look at the settings in about:config to verify. Now print to the label printer making sure it is set to 6x4 in prefs. The letter size printer is now printing in 6x4 inches - WTF? Look at about:config and you will see the settings have actually been changed for the letter size printer! THIS HAS BEEN BROKEN FOR YEARS. How the heck do you use two printers - like if you have to print labels and invoices if the setting change themselves whenever you print?
