Note for everyone who wants to test and for the SRU team. The SRU works
only by updating all three packages, especially the binary package
system-config-printer-udev needs the new cups-filters-ippusbxd package
now.

Bug description:
This is a hardware enablement SRU for Ubuntu 14.04 LTS (Trusty).
From 14.10 (Utopic) on Ubuntu has full support for IPP Everywhere
printing:
1. Printing on IPP Everywhere printers
2. Printing on IPP-over-USB printers
3. When sharing a printer to the network the shared print queue
emulates an IPP Everywhere printer
4. PPD-less printing on IPP network printers (IPP Everywhere, PDF,
PostScript, PCL) without need of a printer setup tool
14.04 *Trusty), the current LTS, supports only (4). An OEM asked
whether we could backport the full IPP Everywhere support to Trusty.
This bug report is about the backport of IPP Everywhere support into
Trusty as an SRU.
Affected are the source packages cups-filters, cups, and system-
config-printer:
cups-filters:
- Add ippusbxd (Support for IPP-over-USB printers), generating the new
binary package cups-filters-ippusbxd. Its installation in Trusty will be
assured by a dependency on it in system-config-printer-udev
- Add rastertopdf filter. This filter allows PWG Raster as input format
for a CUPS queue. This is needed to make shared CUPS printers fully emulating
IPP Everywhere printers (all other requirements are fulfilled by CUPS itself).
- Add conversion rule for rastertopdf filter to the MIME conversion rules.
- Add PPD file for a generic IPP Everywhere printer (on-the-fly
auto-generation by cupsfilters.drv).
- Support for PWG-Raster output activation via a keyword in the PPD file.
- pdftoraster filter: Support for output in the color spaces 18 (sGray),
19 (sRGB), and 20 (Adobe RGB). No color management appropriate to these color
spaces is added yet.
system-config-printer:
- Add auto-setup for UDEV-discovered IPP-over-USB printers using
ippusbxd.
cups:
- Fix priority setting of PWG Raster MIME type, so that PWG Raster
input is actually recognized.
[Impact]
Trusty has a total support life of 5 years, ending in April 2019, but
it does not support the new PWG standard IPP Everywhere for driverless
printing. So in the near future many new printer models which can get
easily supported under Linux as they are fulfilling an open standard
are not supported by Trusty. This is especially very bad for Trusty
being used as pre-installed OS on new PC/notebook/server hardware and
on mobile devices.
[Test Case]
1. Connect an IPP Everywhere printer to the network and try to set it up.
There is no suitable selection in the Make/Model lists (no "Generic IPP
Everywhere Printer").
2. Connect an IPP-over-USB printer to the USB. It gets set up automatically
but with the conventional USB interface, not giving access to the printer's
configuration web interface and other network-printer-typical features.
3. Share a local print queue on your box and try to access this queue with a
mobile device which supports printing on IPP Everywhere printers. The printer
will not be found or be found based on older mobile printing protocols.
After installing this SRU (all three packages) all this will work.
[Regression Potential]
Most changes are addition of new code files and new conversion rules,
there are only a few simple changes in existing code files so the risk
of regressions is very low.
