UNIX Printing
The NIC 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 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. See Running TELNET
(page 5-47) for instructions on how to change the port number
to that used by such applications.
