I have investigated the problem and it is a bug of evince. Both methods shown in the initial posting lead to a PDF-to-PostScript conversion via evince. Firefox is not able to display PDF files by itself and therefore it calls evince in a default installation of Ubuntu. And in the second method evince is explicitly called by the user.
I can print the boarding pass just fine with okular, Adobe Reader, and directly sending it to CUPS with the "lpr" command. -- 8.10 Printed PDF missing parts / corrupt https://bugs.launchpad.net/bugs/293883 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
