Note
•This manual cover general settings only. See your UNIX system man- ual for full details about setting procedures.
The NIC can support UNIX TCP/IP printing in two modes:
•Host-based lpd where a supplied line printer daemon is running on one or more workstations and print data is communicated to the NIC via a TCP/IP port or,
•Printer-based lpd where the printer appears as a host running a line printer daemon.
In general, printer-based lpd is easiest to use on BSD UNIX systems, requiring an entry in the printcap file once the NIC has its IP information. Some UNIX System V systems have restrictions on support of remote LPD printers, requiring that the host-based LPD approach be used. For many operating systems, you have the option of using host-resident printing or print server-resident printing. Each mode has certain advantages.
•The host-resident method can print the username and filename on its banner page; the print server-resident method prints a banner page with the host’s name.
•The print server-resident method requires you to configure the printer only one time, when you install the print server. The host- resident method requires that a printing daemon be installed on every host that you want to be able to print jobs.
Note
•The NIC will also operate with other host-resident print supervisor/ spooler programs that present a print image to the printer over a TCP/ IP port. The base TCP/IP port number can be changed via Telnet, or the NIC HTML setup pages accessed by MAP or a Web Browser. Remem- ber, the actual port is always one higher than the base port number. The status report indicates the actual port number.
