Rated 4 out of 5 stars

in 2.2.0 the printing stops working after one print, restart thunderbird and the same. It's the same as we give mail filtering. with version 2.1.5 it is ok

This review is for a previous version of the add-on (2.2.0).

Thank you for your review, sorry for the issue with the new code. Could you post this issue in the Github repository where I can debug the problem :
https://github.com/cleidigh/printing-tools-ng/issues
There we can communicate. If you can give me some more details like the OS and Thunderbird versions as well as the method that failed. I think this was printing through FiltaQuila? Just want to be clear.
Thanks
Christopher

Update
I have a beta fix that has also been verified by another user. The release should be out shortly.
