Given that the service is oneshot, I need a full output of the journal to see what has happened to said service.

I can start each of these services manually though: sudo systemctl start 'udev-configure-printer@-devices- pci0000:00-0000:00:14.0-usb2-2\x2d2.service' sudo systemctl start ippusbxd@002:033.service In each case ippusbxd gets started for this printer and a print queue auto-created. What I expect is that the services get automatically started (and that worked in 17.04) so that after plugging in an USB printer I can immediately print as the print queue gets created automatically. The "udev-configure-printer..." service works for all USB printers, not only IPP-over-USB (it automatically recognizes the printer typ and does an appropriate setup). This is a regression as we had always automatic setup of USB printers.
