I think that magic that makes it work on a print server is the Linux driver.  So you could hook it to a print server, but you'd need to configure and share the printer from a Linux machine.

Sure, that's the idea.  You could configure/share that printer from a 
Linux machine and have your Windows clients, if any, hit the Linux print 
queue, via either Samba or through CUPS's "LPR compatibility mode."  
Either one will work from pretty much any Windows machine.

But unless I'm misreading the original question, it didn't seem to be 
about Windows machines, but rather getting the printer to work in a 
separate physical location from the K12LTSP server.  I think that's why 
Joseph wanted to hang the printer off of a thin client.  A little print 
server would work perfectly for this scenario.
