Dear sun managers
The original question was:

I got 3 answers, the first was:
> The lpNet processes are startet for each s5-Type remote printer system (as
> listed by lpstat -l). They appear on both machines, client and server, and they
> stay up forever by default (for performance reasons, I think).
> There is a -T option for the lpsystem command, which should tell the lpNet
> processes to terminate after the defined idle time.

I tried the -T option for lpsystem and managed to get rid of the lpNet processes,
but then I found out that they where not really the problem, the problem remained.
Now I think that the lpsched process is the one that steals half of my CPU-time.
I also tried to use the -R option which specifies the length of time to wait
befor trying to re-establish a connection to the remote system, but that did
not fix my problem.
I am using bsd protocol, but that does not solve it either.

The second was:

I'm not running NeWSprint, so I gues this doesn't help.
-------------------------------------------------------------------------
The third was:
> Yes, I have had. This bug was fixed with the patch 101959-06.

I tried this to but it did not fix it...

So, I havn't solved the problem yet.
I will report this as a bug to sun and hope that they can help me.
If someone else have any additional info that could help me I will
be glad to recive it.
Thanks to all who helped me so far.
