Xerox printers can communicate using either protocol.Xerox Services for UNIX Systems (XSUS)XSUS is an application that allows you to manage and print to multiple printers in UNIX and Linuxenvironments. With XSUS you can:• Configure and check the status of network connected printers.• Set up a printer on your network as well as monitor the operation of the printer once installed.• Perform maintenance checks and view supplies status at any time.• Provide a common look-and-feel across the many different suppliers of UNIX and Linuxoperating systems.Supported Printing Models• Workstation-to-printer (Peer-to-Peer): Print jobs are processed and spooled locally on yourcomputer, then sent directly to the printer. XSUS must be installed on each computer.• Workstation-to-Server (Client-Server): Print jobs are processed and spooled on your computerand then sent to the printer to be printed. This model requires XSUS to be installed on both theserver and on the computer.• Server Based: Print jobs are sent unprocessed from your computer and are spooled on the serverand then sent to the printer. This model requires XSUS to be installed on the server only. Individualcomputers can print to the printer by setting up a generic lp or lpr queue pointing to the queue onthe print server.• Network Information Service (NIS) Based: NIS uses a printer configuration map on the server.When new printer queues are added to a print server, only the configuration file in the master NISserver must be updated. NIS clients can then print to any of the queues listed on the server mapwithout setting up local queues.Note: Consult your UNIX or Linux operating system manual for more information on how to set upNIS-based printing.
