I'm sorry that the information provided so far ist too thin. It seems that, if the print-job's media size differs from the printer's default media-size, rastertoqpdl segfaults. My printer is set to A4 media, while all KDE programs use "Letter" by default. This probably has caused the crashes I observed earlier. However, even if rastertoqpdl doesn't crash, the printouts still are completely black.
I've attached a small LaTeX document and the resulting input.ps/input.pdf files to demonstrate the problem. The document size is set to A4 media. # ML-2510_(Ubuntu) is using Splix (rastertoqpdl): # no crash/ black printout; see bug267903.tar.gz/target_media_a4/* lp -d "ML-2510_(Ubuntu)" -o media=a4 input.ps # segfault; see bug267903.tar.gz/target_media_letter/* lp -d "ML-2510_(Ubuntu)" -o media=letter input.ps As already mentioned, the Samsung-driver works fine in both cases. Unfortunatelly, I don't know how to efficiently debug a CUPS filter. I noticed, however, that everything seems to get piped through /usr/lib/cups/filter/pdftoraster before it is fed to rastertoqpdl. Therefore I've created a small wrapper script around pdftoraster which records command-line arguments, environment variables and the output from the "real" pdftoraster, which is then used as input to a "stand- alone" (i.e. not started by CUPS) rastertoqpdl with gdb or valgrind attached. If there is a better way to do this, please let me know. The following debugging packages are installed: cups-dbg libc6-dbg libcomerr2-dbg libgcc1-dbg libgcrypt11-dbg libgnutls26-dbg libgpg-error0-dbgsym libjpeg62-dbgsym libkeyutils1-dbgsym libkrb53-dbgsym libpng12-0-dbgsym libstdc++6-4.3-dbg libtasn1-3-dbg libtiff4-dbgsym splix-dbgsym zlib1g-dbg Yet, gdb still complains about missing debugging symbols. I hope the backtraces help to isolate the problem nevertheless. Please feel free to ask, if you need further information. ** Attachment added: "bug267903.tar.gz" http://launchpadlibrarian.net/17564864/bug267903.tar.gz -- rastertoqpdl segfaults https://bugs.launchpad.net/bugs/267903 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
