Unless you're using TB 75beta, where printing is broken, open Tools/Options/Advanced/General/Config. editor, right-click print_printer, Reset, restart TB, and see if printing works.

Thanks for the suggestion - but it didn't work. The printer works for all other applications and browsers - just not for Thunderbird. I can just forward the email to Microsoft Office to print it out.

Are you able to print to a virtual printer, for example the Microsoft Print to PDF printer using Tbird?

Update: I just noticed you're still on Windows 7 which doesn't have a native PDF printer. Try printing to another virtual printer using Tbird. This is just to test if other printers are also affected.

1. When the first suggestion did not work, I did a system recovery. I checked the Config editor and my Tbird setting is the same as it was before the "restart" change. 2. I just tried to do an Adobe Acrobat XI Pro pdf (using TBird print setting) and it didn't work. 3. I have a new computer with windows 10, and I am getting ready to transfer my files. So maybe it will work on the new computer. Thanks for taking the time to try to help me. I appreciate your efforts :)

That fixed it.. Thanks. All the details in config were for my old printer. The reset found the new device.. THANKS!
