A workaround to be able to print the CUPS test page again is to convert /usr/share/cups/doc-root/images/cups.png to RGBA:
convert /usr/share/cups/doc-root/images/cups.png PNG32:cups.png sudo cp cups.png /usr/share/cups/doc-root/images/ After that the test page prints again. But note that printing 8-bit-per- pixel PNG files directly to CUPS will not work. Those files you have to open with eog, shotwell, GIMP, or any other image application and then print out of the application. ** Also affects: cups (Ubuntu) Importance: Undecided Status: New ** Changed in: cups (Ubuntu) Status: New => In Progress ** Changed in: cups (Ubuntu) Importance: Undecided => High ** Changed in: cups (Ubuntu) Milestone: None => ubuntu-11.04-beta-1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/710881 Title: cups: Test Page /usr/lib/cups/filter/bannertops failed -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
