CUPS.org User: pizza This is the current list of the known Canon Dyesub printers that should be blacklisted. There are still five unknown PIDs, so followup patches will happen once the PIDs become known. (This list is taken from my WIP patch to Linux's usblp driver)

Some USB printers claim to support the USB printer class protocol,
but actually they require special methods for the USB data transfer
so that they do not work with the "usb" backend.
I ask for a feature to blacklist such USB printers so that the
"usb" backend does no longer show them by its "device discovery"
to avoid that end-users set up a print queue with the "usb" backend
for USB printers that do not work with the "usb" backend.
The current example for such printers are the
Canon SELPHY ES-series and CP-series printers, see the
"Updated spooler for Canon Selphy dye-sub printers"
mail thread dated Tue 30 Oct 2012 on the
gimp-print-devel@lists.sourceforge.net mailing list.
