[cups.general] Local filtering when printing to windows printserver - KDE removes filter entry

[Wilhelm]

Hi all,

we are using cupsd / smbspool for printing to printers hosted on a 
remote windows printserver. Therefore the cups-clients need to to the 
filtering local. So I setup the local printers.conf to include the 
nessesary filter definitions. Up to this point all is well and printing 
works.

The problem seems to be the KDE printer-mgr. If someone logs into the 
client using a KDE session, the kde startup procedure somehow removes 
the filter entrys from printers.conf and then I have printers.conf 
(modified, without the filter definitions) and printers.conf.0 (the 
previous working one).

If I set cupsd to LogLevel debug, it says that it is modifying 
printers.conf.

So, the question is: how do I prevent KDE from sending modifying 
requests to cupsd or how do I refuse those modifications ?
