I stumbled on the solution to this problem. On the CUPS website, I found a networking document that addressed how to access standalone print servers on a network (as opposed to accessing print servers on other machines). This document listed proper protocols for various devices, and my Linksys PSUS print server was on the list! So, the correct URI for this server is ldp://ip-address/lp In my case, it is actually: ldp://192.168.1.100/lp. I set that router address to be a static IP address, and the system works great now.
