Ok, so now that you have installed upstream foo2qpdl it is better to report this issue in the upstream forum.
Please note that there are drivers other than foo2qpdl that could work for this printer. Could you try Samsung CLP-300 with the SpliX driver. Note that the SpliX package coming with Ubuntu does not work, as potentially patented stuff got removed there. So use the driver packages on http://www.openprinting.org/driver/splix/ or compile from upstream. Does this work for you? I also looked up the specifications of the 325w and this wifi model also supports PCL 6/5c, so this could give better results. Please try the different PCL6/5c drivers offered under the manufacturer "Generic". Especially try the PCL-6/XL printer with "Foomatic/pxlcolor" and the PCL-5c printer with "Foomatic/hpijs-pcl5c". Which ones work? Which driver gives the best print quality and which the best printing speed? Better results compared to clp-315 foo2qpdl? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/817296 Title: Diagonal streaks when printing some images To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/817296/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
