[FreeNX-kNX] Client-side CUPS printing

[Prakash Velayutham]

Hello Fabian,

Another question is, I hear CUPS 1.2 does not support usermode cups  
daemon like CUPS 1.1 does. Would this affect how the client-side  
printing works?

Where should this wrapper be used, client or FreeNX server? If server- 
side, I think I am having problems at the client-side and how would  
this help in my case. If on client-side, how can I point NXClient to  
the wrapper as the client is a executable binary, not a shell script.
