That's because the patch contains a gtk version check. gtk versions older than 2.24 lie about the PDF print capability so we fallback to PS in that case. This is probably a good thing as it ensures that if the gtk is new enough to correctly report the PDF print capability, the distro will also have recent versions of poppler and ghostscript that have fixed the PDF printing bugs. > Would it be better to offer a preference to override detection and > enforce PDF? Probably not. There is no immediate benefit to using PDF. This is more about providing longer term benefits such as: - Avoiding rasterization of transparency on printers that can print PDF directly - Avoid unnecessary conversion of PS to PDF then back to PS in cups - As PDF is replacing PS as the standard printer language, most of my cairo PS/PDF work will be focused on improving and optimizing the cairo PDF output. The PS surface will only get bug fixes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/332472 Title: Thunderbird cannot print to PDF -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
