Please start system-config-printer using the command line system-config-printer --debug 2>&1 | tee log.txt
and do the same attempts to set up your printer as before, one with the DNS-SD/IPP choice and once with IPP driverless. After that please attach log.txt (do not compress) to this bug report. Try also the following: Run the command driverless You get some lines of output. Each line is the URI (Unified Resource Identifier) of one of the printers in your network which supports driverless printing. Is there one corresponding to your HP Color LaserJet MFP M476dn? You recognize it if it by whether it contains the host name, IP address, make, or model name of the printer. Have you found the correct URI? Then run lpadmin -p LJM476IPP -E -v URI -m everywhere replacing URI by the URI you have found with the "driverless" command. This creates a print queue for your printer, using driverless IPP network printing. Please post all screen output here. Does this print queue work? Can you also attach (in a separate comment) your /etc/cups/ppd/LJM476IPP.ppd file? Please run also ipptool -tv URI get-printer-attributes.test > ipp-attrs.txt replacing URI again by your printer's URI and attach (in another comment) ipp-attrs.txt. Please do not compress any of your attachments nor package them together. Attach them one-by-one. ** Changed in: system-config-printer (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1707193 Title: adding printer with IPP network printer via DNS-DS fails due to "There was an error during the CUPS operation: 'server-error-internal-error'" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/1707193/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
