Chapter 5 Configuring the Internal Ethernet Adapter for TCP/IP

System V UNIX
Printing in a System V environment requires the use of an interface file.
It also consists of:
the lp printer interface program
the lpsched printing scheduler
a set of programs acting as interfaces between the scheduler and
printing device.
The scheduler copies the files into a spooling directory and calls the
interface program when the job is ready to go the Internal Ethernet
Adapter. It processes the job according to the script’s setting and sends
it to the printer for printing.
The interface script is usually kept in /usr/spool/lp/admins/lp/
interfaces and carries the same name as the associated printer. It is
copied from the original interface file in /usr/spool/lp/model when the
lpadmin command is executed.
The interface script is called with the following syntax:
ps203
reqid username copies options file1 ...
where:
ps203
Name of the interface script which is also the printer name
on the host
requid
Print job identification
username
ID of the user requesting the job
title

copies
Number of copies for each file to be printed
options
