Okay, finding time to deal with this again. Now I'm getting inconsistencies on the left-side port. Behaviour seems to vary according to previous history: Printing the test page first gave me the already-reported garbled output, switching off the printer and then switching it on again and retrying the printout gave me no activity on the printer and a hung print job. So I suspect it's not the USB port that made the difference but previous history and dirty state somewhere. What's the best way for get a full reset of all relevant state?
For reference, I'm attaching the cups error log, timestamps of my activities: 17:48:38 I started system-config-printer 17:49:38 I opened the Properties context menu entry on the printer 17:50:25 I let the Properties dialog print the test page (not the self-test page) 17:51:10 I confirmed the OK button on the "test page submitted" dialog box -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1512012 Title: Kyocera Mita FS-1900 prints garbage Status in cups package in Ubuntu: Incomplete Bug description: Using the PPD from http://www.kyoceradocumentsolutions.de/dlc/de/driver/all/linux_ppd_s_ksl_8 .-downloadcenteritem-Single- License.downloadcenteritem.html?langLabel=de_de&actURL=/content/sites/kme/de/de/index/serviceworld/downloadcenter (the German one, not sure if that could make a difference). Followed the instructions on https://wiki.ubuntu.com/DebuggingPrintingProblems. Steps in "USB Printer" gave the following results: 2. lsmod | grep usb would give several modules (is usblp the right one? the page doesn't tell) 3. tailing the syslog would show me USB activity during plug and unplug. 6. lsusb output seems legit: Bus 001 Device 013: ID 0482:0004 Kyocera Corp. 8.

From the DebuggingPrintingProblems page, I tried both usb-unidir-default and usb-no-reattach-default, with no discernible difference. (Things were slightly complicated by the docking station being entirely unresponsibe on three of six USB ports. I don't know whether the ports of the drivers are at fault here, but I guess that's unrelated to CUPS.)
