Thanks for the clarification.  I will look into an
alternative way to accomplish my goal.  

I am printing at the server for a couple of reasons. 
The first reason is speed.  We are running in a citrix
environment with several remote locations with lame
bandwidth.  The pdf, (which is mainly a scanned image)
is physically located close to the citrix server. 
Viewing the pdf works fine speed wise.  When it is
time to print though it takes forever. So my solution
was to develop a server side process where the client
initiates a print request to the server.  Speed has
dramatically increased with this method.

The second reason is timestamp and logging.  When
using the server side printing, I can add a
timestamp/printed by line at the bottom of the page as
well as track in a database who printed the file and
when.  It works great.

Thanks for all your help.
