Weirdest error today with printing. Upgraded my FreeBSD (source recompiled of 10.2p6), after that wanted to print from my recently upgraded Ubuntu 15.10 desktop. Didn't want to print, got: "Filter failed" in cups jobs screen. First I thought it was due to the FreeBSD upgrade, but after a while I figured out an Ubuntu 12.04 laptop still printed fine, as well as a PC-BSD 10.2 laptop.
Error messages on FreeBSD cups server were not very helpful, with things like:
(/usr/local/libexec/cups/filter/rastertopdf) stopped with status 1.Or
prnt/hpcups/HPCupsFilter.cpp 530: cupsRasterOpen failed, fd = 0Anyway, after I discovered it must be my recently upgraded Ubuntu 15.10, and I probably hadn't tried to print after that, tried to remove and reinstall the printer. That didn't help. The final magic was a suggestion:
lpadmin -P HP-LaserJet-cm1415fnw -m rawAfter that thinks worked, weird, weird, weird.
