Can't print emails or any saved Thunderbird files. I click on FILE>PRINT and get the print preview, butwhen I click on "PRINT" I get a "printer offline message". I can print from Microsoft Word or PDF files and any other program. It appears that everything worked well until the latest Windows update was installed. I am using an HP printer and print via HP's Smart Print software which I believe is the default. I'm not sure if this is a Thunderbird issue or another screw up by Microsoft. Thanks for your assistance.
