Well, it wasn't MY idea, let me assure you.  Even the SAP consultants are 
telling the guys to get rid of NT and stick in something Unix.  Yeah, we're 
at these 4 servers (they thought they had to "distribute the load") and we're 
not even halfway done with implementation yet!

The idea, though, was to let SAP dump printing on us.  Our SAP instances are 
hosted outside (not my idea, again) the company.  Shooting print jobs to our 
own intermediate server enables us to control things a little better since we 
can't touch the SAP servers.  Sure, there's no reason it couldn't go directly 
to the printer.  And since they're largely a Wintel shop...

Interesting.  Any facts to back this up?  Is one slower than the other?  I'm 
printing labels to a bunch of Zebras on JetDirects (under NT4) and I use LPD 
on my stuff and have no problems at all  These guys are using the 9100 stuff 
and so far have had nothing but problems.
