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. Device id seems legit, usb_printerid /dev/usb/lp0 says ID:FS-1900;MFG:Kyocera;CMD:PCLXL,PostScript Emulation,PCL5E,PJL;MDL:FS-1900;CLS:PRINTER;DES:Kyocera Mita FS-1900;CID:HP Laserjet 4050 Series;
10. lpinfo -v has this to say about the printer: direct usb://Kyocera/FS-1900?serial=AAP2925070 (other non-network, direct printers listed are "direct hp" and "direct hpfax", could be a modem jack I never cared about, could be something emulated, no idea)
Printing the test page gives me two sheets of paper, the first mostly empty except for three lines each starting(?) with a single full stop character, and a second with these lines (note the initial blank on most line starts, could actually be multiple blanks):
ERROR

OFFENDING COMMAND:

The printer seems to be emitting a line with a full stop every 20 lines or so, the full stop in the message above is somehow connected to that.
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.)

Hm. Some more testing revealed an odd difference between the USB ports on the left and on the back side of my docking station.
The back ports work as one would expect: printer is recognized and gets registered when plugged in, and gets unregistered when unplugged; USB drive when plugged in gets recognized and has its directory shown in Thunar (XFCE here).
The left-side ports show inconsistent behaviour: The USB drive gets recognized and has its directory shown, but plugging in the printer does not provoke even a single new line in /var/log/syslog.
I'm wondering how such a difference is even possible.
For reference, here's the syslog from plugging the Kyocera to a back-side port:
