Default printer troubles with Thunderbird

ตั้ง Printer ให้โปรแกรม Thunderbird แล้วไม่จำค่า Printer Default ที่เราตั้งไว้

If you can't print from Thunderbird, or if Thunderbird won't recognize the computer's default printer:

1. In Thunderbird, go to Tools - Options.
2. Under Advanced, on the General tab, click on the Config Editor button.
3. Scroll down to the line starting with print.print_printer. If you don't have that line, then everything should already be set correctly.
4. Right-click on the print.print_printer line & choose Reset.
5. Close the configuration window, then click OK to close the Options window.
6. Close Thunderbird.
7. Make sure that the correct default printer is selected. To do so, go to Start - Settings - Printers and Faxes. The one with the small checkmark is the default. To set a different printer as the default, right-click on it & choose Set as Default Printer.
8. Reopen Thunderbird.
