UNIX Configuration
The Elite 21 printer can support UNIX TCP/IP printing in two modes:
• Host-based lpd where a supplied line printer daemon is run on one or more
workstations and print data is communicated to the printer 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 printer has its IP information. Some UNIX System
V systems have restrictions on support of remote lpr/lpd printers, requiring that the
host-based lpr/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 printer 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 WebAdmin. Remember, the actual
port is always one higher than the base port number. The Network Status page
indicates the actual port number.
Between the host-based and printer-based TCP/IP printing capabilities, the Elite 21
printer works with:
All UNIX systems that support lpd/lpr
System V Rel. 4 (on 386 platforms)
DEC ULTRIX RISC Versions 4.3 and 4.4
DEC OSF/1 Versions 2.0 and 3.0
