Thank you for your error_log. According to the error_log, Ghostscript or hpijs crashes with a segmentation fault. I have copied the Ghostscript command line from your error_log and run it with some arbitrary PDF files. On Jaunty I can reproduce the segmentation fault and according to /var/log/syslog it is a segmentation fault in hpijs. On Karmic Ghostscript completes its job, but produces a lot of warnings:
prnt/hpijs/hpijs.cpp 389: unable to set key=Quality:SpeedMech, value=1 Shiyun, Dave, Aaron, can someone of you look into what fixed the segmentation fault in hpijs (and perhaps provide a patch) and also have a look at what causes the warning in Karmic's HPIJS? Ghostscript in Jaunty is 8.64, in Karmic is 8.70. HPLIP in Jaunty is 3.9.2, in Karmic is 3.9.8. ** Changed in: hplip (Ubuntu) Status: Incomplete => Invalid ** Changed in: hplip (Ubuntu) Status: Invalid => Confirmed ** Also affects: hplip Importance: Undecided Status: New ** Changed in: hplip Status: New => Confirmed -- Duplex printing doesn't work on HP Officejet Pro 8500 https://bugs.launchpad.net/bugs/428588 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
