Can't figure out how to use cops to print to a network print server

[Mike Keithley]

Hello list,

I'm using slackware 10.2 with a 2.6.13 kernel.  I am also using the cups 
distribution that came with the slackware.

I also have a Linksys print server called psus4.  This is a small box on 
a node on my router that serves a printer through a USB interface.  The 
printer is an HP LaserJet 1200.  The system works fine in Windows and any 
machine on the network can print to the printer.

I can't figure out how to tell cups to properly send data to this network 
printer.

It appears the little box supports the IPP, AppleTalk and Netbeos 
protocols.

I have no problem telling cups the IP address of the print server. 
The question is what protocol to use.

I tried using the IPP protocol but the web interface changed 
it to http (which the box doesn't support).  If I print a test page, I get 
multiple copies of this page (which looks as expected); and the server box 
appears to be choked or hung (you cannot access its web interface), and 
must be reset.

Can someone here help me?  Thank you very much.
