The following example adds an AppleTalk printer called NewPrinter to the lpr spooling system.
1) Edit /etc/printcap to include the following entry.
lp|NewPrinter|AppleTalk|postscript|PostScript:\\
:lp=/dev/null:\\
:if=/usr/spool/lpd/NewPrinter/ifilter:\\
:of=/usr/spool/pd/NewPrinter/ofilter:\\
:nf=/usr/spool/lpd/NewPrinter/nfilter:\\
:sd=/usr/spool/lpd/NewPrinter:
This entry sets NewPrinter as the default printer. The special name lp
in the above entry is used to designate NewPrinter as the default
printer. Please note that there can be only one default printer.
All the names in the first line of the above entry are synonyms for the
printer you are configuring. Any of these names may be used when
invoking lpr from CommandShell.
2) Set up a special spooling directory to hold print requests for the newly
added printer.
cd /usr/spool/lpd
mkdir NewPrinter
Make sure to have the owner and group correctly set to daemon on the
spooling directory, and also that permissions are set to 775.
3) Set up the filters.
cd /usr/spool/lpd/NewPrinter
cp ../AppleTalk/ifilter
Make sure to have 755 permissions on the file ifilter.
4) You need to specify the printer information that you would normally
enter through the Chooser. You do this by editing the Printer variable
in the file ifilter. For example:
Printer="NewPrinter:LaserWriter@De Anza 3/1st Floor"
Link ifilter to two other files as shown below.
ln ifilter ofilter
ln ifilter nfilter
5) Make sure that lpd daemon is running.
6) Enable and start the printer using the lpc command. For example, enter
the following commands:
lpc enable NewPrinter
lpc start NewPrinter
Once the printer is enabled and the spooling daemon is started, enter
either of the following commands from CommandShell.
lpr filename
or
lpr -PNewPrinter filename
For filename, type the name of the file you want to print. In both the above cases, the file will be printed to the printer NewPrinter, since it is the default printer.
You can use this procedure to configure additional printers to the spooling system and enable printing with lpr.
