Comment # 113 on bug 920937 from Johannes Meixner

From an USB expert I got the information that
the printer's firmware is the root cause of the issue.

When the libusb-based CUPS backend 'usb' is used
something in the printer's firmware does not behave well
which leads to failures.

In contrast up to CUPS 1.5.4 where the CUPS backend 'usb'
uses the usblp kernel module the printer's firmware is used
in a bit different way where it works.

Because in very most cases (i.e. for very most printer models)
the CUPS 'usb' backend "just works" (otherwise there would be more
bug reports here at SUSE and also at least one at CUPS upstream),
I assume that the CUPS 'usb' backend is basically o.k.
but in some special cases (i.e. for some printer models)
it needs to do some model specific special stuff.

Fortunately the libusb-based CUPS 'usb' backend already
supports printer model dependant special case handling
via so called "USB quirks", see the comments in
/usr/share/cups/usb/org.cups.usb-quirks (excerpt):

When a particular printer model does not work with the defaults
of the libusb-based CUPS 'usb' backend, it might help to specify
model specific appropriate "USB quirks".

Usually one should have selfmade "USB quirks" in a separated file
like /usr/share/cups/usb/selfmade.usb-quirks (the 'usb' backend
reads all files in /usr/share/cups/usb/).
