Bug#718567: cups: ipp14 backend cannot be set

[Gabor Kiss <kissg@ssg.ki.iif.hu>]

Package: cups
Version: 1.5.3-5
Severity: normal

Dear Maintainer,

The problem is the same as told by others ipp backend does not work
with some printers after squeeze->wheezy upgrade (CUPS 1.4 -> 1.5).

I tried to follow Till's advices in order to use ipp14 backend
(see https://bugs.launchpad.net/ubuntu/+source/cups/+bug/945028 comment #56
and http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=712719 comment #44)
but command failed:

# lpadmin -p Canon -v ipp14://this.is.my.print.er/ipp/printer
lpadmin: Bad device-uri scheme "ipp14".
# 

So I had to do the discouraged replacement of /usr/lib/cups/backend/ipp.
