According to Novell, setup requires switching to bindery mode in PCONSOLE. Here's some information from Novell's Network Support Encyclopedia about this:
"Network-direct print devices and their installation programs are designed to look in the NetWare 3.1x bindery for network printing information. In order for these devices to work on your NetWare 4 network, you should use the bindery emulation mode when installing them."
