What print server/printer adapter are you asking about? Helps narrow down the best solution.
Searching for a printer attached to another computer is ALOT easier than searching for a dedicated print server with a printer.
Generally other computers CAN'T see the print server unless they either:
-know the ip address of the print server
-search for it with discovery software
-install the print server client software
I have 2 printers on the network like you describe, only the big-wigs have access, the rest of the network can't see them at all unless they knew ip address, or searched with discovery software.
<< I've never seen printer firmware that would let you limit who can get to a printer. Why not just plug the printer in parallel to the computer? >>
In a domain setting you can use access lists to block users from printers attached to other computers, even if its attached to Win98 computers.
