Raymond,

Some (maybe many) print servers are not 
well suited for spooling print jobs from 
multiple clients. Configuring one host (Linux,
Win*, WhatHaveYou) to spool and queue 
print jobs and have that machine alone 
submit print jobs to the device print server 
boxes might work out better for you. I 
prefer Linux because I have fewer CALs to 
buy (or limitations).
