Olaf, please send a mail with the errors to me and to Lars Uebernickel 
(larsuebernickel@gmx.de).

The actual state is:

The GNOME version was brought very far in last year's Google Summer of 
Code. Level 3 was implemented. Missing is the size and some layout 
issues are still to solve.

The Qt dialog has a completely implemented level 2, recently finished by 
Lars Uebernickel, financed by a German federal government agency. For 
level 3 there are only code pieces which are not activated currently.

Ubuntu 10.10 at the earliest, but only if we get enough man power. I 
asked Canonical whether they help funding (no answer yet). I also posted 
a GSoC project idea for patching toolkits and applications.

We will have to release with level 3, as access to the PPD options was 
available before and removing this feature would be a regression.

For call-in from Japan I have set up an evening session on Thursday 
April 15. This falls into the morning in Japan.

Demos of the Common Printing Dialog will be done with the real 
implementations of it. For call-in participants I can perhaps make a 
Ubuntu package so that one can boot a Ubuntu live CD and then install 
the package to try out the dialog.

The problem occurred when ESP Ghostscript got merged into GPL 
Ghostscript. Since then Mike Sweet did not do any maintenance work on 
the CUPS Raster output device any more. I have fixed many bugs in it in 
the time up to now, but as I am not a Ghostscript expert I did not 
succeed to fix all bugs. The Ghostscript developers at Artifex do no do 
much on this driver, too.

It would be great if someone could help here. CUPS Raster is one of the 
three standard printer driver architectures (standardized in the LSB).

This session will be held by Mike Sweet, it is as in the previous years 
mainly planned development for the next version (1.5).

Netbook printer driver are not planned for GSoC. What is planned is to 
have a session about netbook printing on the OpenPrinting Summit.

Could also be an opportunity to couple a printer driver tutorial for the 
Japanese manufacturers.

Probably yes, and I think we should change it. There are a lot of 
printers (especially laser printers) which do not have all these for 
hardware features implemented.
