Blank pages printed for postscript files on cups 1.2

[Damien Brémont]

We are having problem since a recent upgrade to cups 1.2 (cups-1.2.1-1.2) on a FC5 (2.6.16-1.2122_FC5smp)

Data configuration files have been fully rewritten so has to be compliant with new structure from zero.

But..., since the new version we are having problems to print ps figure.
In these case, we only have blank pages on our HP Laserjet 4350 printers.
The PPD used is default Postcript one and we are connected through socket:// to the cups server. Client are also running under FC5 and we are printing from Xfig or with lpr command for testing.

There are no mistakes in log file :
I [05/Jun/2006:17:50:24 +0200] Adding start banner page "none" to job 9905.
I [05/Jun/2006:17:50:24 +0200] Adding end banner page "none" to job 9905.

N [05/Jun/2006:17:50:25 +0200] [Job 9905] Print file accepted - job ID 178.

We have found two ways to print it :
-First by editing the postcript file and deleting %!PS-Adobe-2.0 (not fun to do for every job)
In this cas it generates a warning logged, but the result is good !
W [05/Jun/2006:13:19:22 +0200] [Job 9848] This document does not conform to the Adobe Document Structuring Conventions and may not print correctly!

-And the second by printing in raw mode lpr -raw test.ps (but we don't like that mode ans it's not easy to change every time)

That must be filter problem, so i give the mime.type section about postscript (default, may help ? )
application/postscript          ai eps ps string(0,%!) string(0,<04>%!) \
                                contains(0,128,<1B>%-12345X) + \
                                (contains(0,1024,"LANGUAGE=POSTSCRIPT") \
                                 contains(0,1024,"LANGUAGE = Postscript") \
                                 contains(0,1024,"LANGUAGE = PostScript") \
                                 contains(0,1024,"LANGUAGE = POSTSCRIPT") \
                                 (contains(0,1024,<0a>%!) + \
                                  !contains(0,1024,"ENTER LANGUAGE")))

We also have problems when printing PDF file, and excel files from Mac OS 10.4 client connected to the linux cupsd server
(PDF generates Postscript mistakes, Excel files can't be printed in landscape mode)
I think they are related to the first

Your help is welcome ;-)

Thanks in advance
