Oi,
as talked about in the OpenPrinting steering committee meeting I am
posting here some info about the printing part of the LSB Summit 2006 in
Boston.
My slides (and pictures) you can find here:

- Only OpenPrinting part which can enter in LSB 3.2 is OpenPrinting
vector, as the appropriate interface is part of ESP GhostScript 8.15.1
or later and this ships with all major distros (Red Hat/Fedora, SuSE,
Mandriva, Ubuntu, Debian). Official release of the Vector API is
prepared during this month.
- PCM and SM are independent of the OpenPrinting vector driver and they
are not in the distros yet, so they can only make it into LSB 4.0.
- PAPI, JTAPI, ... are not in the distros yet, so they are only
interesting for LSB 4.0, too. In the OpenPrinting Steering Committee
we talked about how to get them into the distros. For PAPI we agreed
on that it should be made part of the CUPS package, especially as Mike
Sweet is one of the authors of PAPI. Therefore I have posted the
following feature request for CUPS 1.3:
http://www.cups.org/str.php?L1767
But there is no reaction from Mike Sweet up to now.
- Standardized directories are also a candidate for the LSB 3.2. After
the meeting there came up a thread in the CUPS general forum/mailing
list that a user has a problem with SE-Linux-enforced Red Hat that his
printer driver did not work. It was dropped in /usr/local, whereas
SE-Linux accepts printer drivers only in standard CUPS directories ny
default. With standard directories such problems should go away.
For the PPD file tree it was decided to have sub-directories for the
different UI languages, so that one can easily make language packages.
The PPD file names itself should also contain language tags.
- The only possibility to provide a printing interface to applications
(ISVs) in LSB 3.2 is the CUPS API, but it suffers the problem that
only Linux has standardized on CUPS and many other Unixes (like BSD or
Solaris) not. Now there is the Question whether LSB should be
considered as LINUX Standards Base or Unix Standards Base.
