Package: cups
Version: 1.5.0-13
Severity: normal
Tags: upstream patch
Hi,
The USB receipt printer Epson/Seiko TM-T88IV (M129C) is not recognized by the
cups usb backend.
This printer returns to Vendor-Specific values for bInterfaceClass and
bInterfaceSubClass USB attributes which prevents it to be properly dretected as
a 'regular' printer.
The output of 'lsusb -v' for such a printer is attached.
It's correctly detected by usblp, since several years, thanks to this patch:
http://www.spinics.net/lists/linux-usb-devel/msg03603.html.
I've made and tested successfully the same kind of patch for backend/usb-
libusb.c of the original source tree of cups 1.5.0.
A related drawback is that this device doesn't have any IEEE-1284 device ID, so
the output of backend/usb is something like direct
usb://Unknown/(null)?serial=J4LG008211
"/(null)?serial=J4LG008211""/(null)?serial=J4LG008211" "" ""
It could also be fixed using hard-wire values, but I haven't done such
additions in my patch.
This device ID problem doesn't prevent the printer to work perfectly.
Let me know if you want me to do additional tests - I really need this printer
to be recognized properly by cups.
(I have tested the lastest debian cups version 1.5.0-16, and the problem is
still there)
I filled the same bug report in the cups bug tracker some months ago, but they
refuse to fix it, as they don't want to support non-standard printers. IMHO
it's still a regression caused by the transition from usblp to libusb, but
anyway ...
Thanks

This has been fixed by upstream in cups 1.6.0; hereby marking this bug as
fixed in said version.
I will see if I can backport that fix to Wheezy.
