If the printer is a remote printer, a remote connection is used. You must use the rm symbol to specify the
name of the machine to which the printer is attached. You must also specify the printer reference name
with the rp symbol, as well as the lp and sd symbols
10.7.4 Line Printer Daemon Filter Directory
The filter directory for the lpd daemon translates data that you want to
print into the format appropriate for your printer. You must specify the
filter that matches each printer on your system. For example, to print files
with the LN03R printer, you would use the ln03rof filter.
You can specify an accounting filter with the if symbols and an output
filter with the of symbol. Output filters filter text data to the printer
device if accounting is not enabled or if text data must be passed through a
filter. For example:
if=/usr/lbin/ln03rof
of=/usr/lbin/ln03rof
Refer to the lpd(8) reference page for more information on using filter
capabilities. The reference page lprsetup.dat
(4) lists the available print
filters located in the /usr/lbin directory. For printers not listed in the
reference page, consult the documentation or refer to the printer
manufacturer for filter information.
For printers not supplied by Compaq, consult your printer manual for filter
information.
10.7.4.1 General Purpose Print Filter
The pcfof print filter is designed to accommodate many different printers
through the use of a printer control file (PCF). PCF files contain printer
control strings to set up and select printer-specific features such as paper
tray selection, duplexing, and printing orientation. The filter is designed to
work with text, ANSI, PCL, and auto-sensing multilanguage PostScript
printers, but will not work with PostScript-only printers.
PCF files are text files. You can use any text editor to modify an existing
file to customize printing behavior or create a new file for an unsupported
printer. Note that PCF files provided in Tru64 UNIX are replaced during
an installation update, so you should take care that you preserve any
