HP 310X - Manual (Page 106)

Setting up LPR/LPD on Macintosh
systems
for HP Jetdirect 175x external print server/Internet connector for USB
and HP Jetdirect 310x external print server/Internet connector for
USB
The setup for LPD (Line Printer Daemon), also known as LPR (Line
Printer Request), involves setting up the print queues and creating a
port for printing.
Prerequisites:
Mac OS v.8.6 or higher ●
LaserWriter 8, version 8.5.1 or higher ●
Desktop Printer Utility 1.0 or higher ●
Also verify the general LPD prerequisites . ●
Reference on queues
In the procedure below you will set up a print queue for each printer
or printer personality (PCL or PostScript) used on each system. Also,
different queues are required for formatted and unformatted files. You
can use the queue names listed in the following table.
raw no processing
text carriage return added
auto automatic
binps binary Postscript
defined by user; optionally including
commend strings before and after the print
data
Meaning of the queue names:
The line printer daemon treats data in an text queue as unformatted
or ASCII text, and adds a carriage return to each line before sending it
to the printer. (Note that the actual observed behavior is that a PCL
line termination command (value of 2) is issued at the beginning of
the job.)
