Installation guide

The DIGITAL UNIX system also contains more sophisticated security
features. These features are described in the Security manual.
4.6 Print Services
The DIGITAL UNIX system includes the traditional BSD UNIX capabilities
for printing files. The system supports a print spooler for queuing print jobs
to one or more printers. The /etc/printcap file describes the printers
available, including their characteristics. You can print files on a remote
DIGITAL UNIX system over the TCP/IP network, just as you can on an
ULTRIX system. You can print files on a local or remote PostScript printer,
files on a printer connected to a LAT port, and files that contain the
appropriate PostScript prologue print without modification.
Although the DIGITAL UNIX system supports basic print capabilities, it
does not support the PrintServer for ULTRIX software to print files on the
DIGITAL family of PrintServer network laser printers. DIGITAL offers an
optional software package for supporting PrintServer printers on DIGITAL
UNIX systems; licenses for this software are bundled with the printers
themselves, and the software is available separately. Contact your local
DIGITAL salesperson for further information about PrintServer support.
See the System Administration manual and Network Administration
manual for information on setting up printers.
The following list compares the basic printing capabilities of the DIGITAL
UNIX system and the same capabilities on an ULTRIX system:
The print management and use commands are the same.
The lprsetup utility is available and performs the same tasks on a
DIGITAL UNIX system as on an ULTRIX system; namely, creating
entries in the /etc/printcap database, creating spool directories,
creating accounting files, and so on. Other commands, such as lpq,
lprm, lpc, lp, and pac are the same as the equivalent commands on
an ULTRIX system.
The line printer daemon has moved to a new directory.
The print services on DIGITAL UNIX and ULTRIX systems are
controlled by the line printer daemon (lpd). On DIGITAL UNIX
systems, lpd is stored in the /usr/lbin/lpd directory by default. On
ULTRIX systems, lpd is stored in the /usr/lib directory.
The script that starts lpd has moved to a new directory.
When you reboot a DIGITAL UNIX system, the system runs the
/sbin/rc3.d/S65lpd script file to start lpd. On an ULTRIX system,
lpd is started by the /etc/rc file at boot time.
The name of the spooling directory has changed.
