Christian, first, it seems that you did "cupstestppd" on a PPD file which is not auto-generated:
---------- $ sudo cupstestppd /etc/cups/ppd/Kyocera-ECOSYS-P6026cdn.ppd /etc/cups/ppd/Kyocera-ECOSYS-P6026cdn.ppd: FAIL **FAIL** Missing choice *Option18 SDCard in UIConstraints "*KCCollate CustomBox *Option18 SDCard". **FAIL** Missing choice *Option18 SDCard in UIConstraints "*Option18 SDCard *KCCollate CustomBox". WARN Datei einthält gemischt CR, LF, und CR LF Zeilenmenden. WARN Size "A5" should be "149x210mm". WARN Size "A6" should be "105x149mm". WARN Size "B6" should be "128x182mm". WARN Size "OficioII" should be the Adobe standard name "FanFoldGermanLegal". WARN Size "P16K" should be "7,75x10,75". WARN Size "OficioMX" should be the Adobe standard name "Oficio". ---------- This seems to be from a manufacturer-supplied PPD file. The auto- generated ones do not have "UIConstraints" lines. They also do not contain mixed line ends. Also sorry for giving you a wrong "ipptool" command line. Please run the command line ipptool -tv ipp://KM15881D.local:631/ipp/print get-printer- attributes.test > ~/attrs.txt The file get-printer-attributes-2.0.test only came with a later CUPS version. Please attach the attrs.txt file. *.O files are generated by CUPS, to put the original version of a PPD file when they change or replace it. Only the files without ".O" are relevant for their print queue. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1813825 Title: "driverless" printer workflow has bad usability/ is partly broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1813825/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
