Mozilla Thunderbird Defaults To The Wrong Default Printer

Mozilla Thunderbird has a bad habit of remembering the default printer, rather than pulling the default printer from your Windows (OS X? Linux?) preferences every time.

Thus, if you set up Thunderbird when you have one printer as the default, and then change the default printer, Thunderbird will still try to print to the old default printer.

Fix it as follows:

• Open Thunderbird
• Go to the Tools menu
• Go to the Options submenu
• Go to 'Advanced'
• On the 'General' tab, choose the 'Config Editor' button
• Find the “print.print_printer” option
• Right click on it and choose 'Reset'
• Close Thunderbird
• Check in Windows to ensure the correct printer is chosen as the default printer
• Re-open Thunderbird
