The following printer, when attached via USB fails to work
port 2 addr 2: full speed, self powered, config 1, SAMSUNG Laser Printer ML-4600(0x3004), SAMSUNG ELECTRONICS CO., LT(0x04e8), rev 1.00
Peter van Heusden identified the problem to be the bi-directional mode. When
adding the quirks as given below *OR* chmod a-w /dev/ulpt0 CUPS will print
just fine.
Please note that under the new USB stack developed by Hans Petter Selasky
the printer works out of the box. This, and usb/112944 leave me to believe
it is a more general problem with bidirectional support under ulpt(4).
Perhaps HPS can comment on the architectural differences between the old and
his new ulpt(4)?
PS: Whitespace and sorting in usb_quirks.c are, well, interessting.
