I've never had trouble printing before, even after switching to beta a few weeks ago. But this most recent update to Beta 75.0b1 (64 bit) leaves me unable to print. If I click on an email and I try to print to any printer, it says "Printing message...." in the lower left and then just sits there until I do something else. It doesn't matter which printer I use - my PDF printer, my Laserjet printer, Brother printer. I have no trouble printing from Windows 7 to any of my printers.

Other info: (1) I went into Config Editor and "Reset" the print_printer. No help. (2) When I choose Print Preview the preview looks lovely on the screen. But if I choose "Print..." it fails to print as well. (3) No matter which printer I choose, Thunderbird never actually sends data to the printer's queue. Would love to see a trace of what's happening! (4) I am willing to spend time on this with a dev or super user. I really would like to fix this!
