[FreeNX-kNX] cant get working remote printing

[Eric Bazzana]

I dont know much of bash, but i think that what is happening is:

nxnode.nxnode_func is a dispatcher for operations, among
others, --startsession and --addprinter.

--startsession invokes startsession, which in
turn invokes node_start_applications in background

--addprinter invokes cmd_node_addprinter  in background

cmd_node_addprinter set CUPS_SERVER, BUT as it is in background bash forks
a new process with its own environment, that do not affect orginal process
environment, right?

node_start_applications set CUPS_SERVER, IF directory $session_id/cups
exists. (cmd_node_addprinter run in a separate process, asynchronously, and
at the time of evaluation that directory does not exists. IF there is the
directory, we are in another process and do not affect original, right?)

- this is because i dont have CUPS_SERVER setted. Now, how can i fix it?.

thanks, Eric
