First try to reset Firefox printer settings, if you are still unable to print you can then reset '''all '''firefox printer settings.
You mentioned there is no print.print_printer when you go to about:config. You have to type it in the actual '''filter '''field to pull it up.
Reset firefox printer settings:
1. In the Location bar, type about:config and press Enter.
2. In the '''Filter''' field, type '''print.print_printer.'''
3. '''Right-click''' on the print.print_printer setting and select '''Reset.'''
4. At the top of the Firefox window, click on the Firefox button (File menu in Windows XP) and then click Exit.
'''The first way was just simple reset of firefox printer settings. However, if it failed to solve the problem then you need a full reset of all firefox printer settings.
1. Open your profile folder:
''At the top of the Firefox window, click on the Firefox button, go over to the Help menu (on Windows XP, click on the Help menu) and select Troubleshooting Information. The Troubleshooting Information tab will open.''
2. Under the Application Basics section, click on Open Containing Folder. A window with your profile files will open.
''Note: If you are unable to open or use Fire​fox, follow the instructions in Finding your profile without opening Firefox.
3. At the top of the Firefox window, click on the Firefox button (File menu in Windows XP) and then click Exit.
4. In your profile folder, copy the prefs.js file to another folder to make a backup of it.
5. Open the original prefs.js file in a text editor (such as Wordpad).
6. Remove all lines in prefs.js that start with print. and save the file.
