When defining these variables, remember each is case sensitive. Define them as illustrated in these descriptions.
NPDIR_PATH (mandatory) Define the directory location of chr, banner, onlcr, and npscramble binaries. Usually /usr/ local/bin.
These binaries must be copied over from the host software.
COMM_PROG (mandatory) Specify a communication program to transfer the data to the Internal Ethernet Adapter (i.e. npwrite, rsh). If the program is npwrite, define the UNIT_PORT variable. Otherwise, define the LP_DEST variable.
PRINTER_TYPE (mandatory) Specify printer type (i.e. raw, ascii, ps, hp, gen7170).
UNIT_PORT (conditional) Specify the Internal Ethernet Adapter port name (i.e. prn). Use only when COMM_PROG is defined as rsh.
For example:
#END_MARK_1
NPDIR_PATH=./USR/LOCAL/BIN
COMM_PROG=rsh
UNIT_NAME=spike
LP_DEST=d1prn
PRINTER_TYPE=hp
BANNERPAGE=1
#START_MARK_1
NOTE: Additional variables can also be identified within this variable section as indicated by BANNERPAGE=1. Some other options include ASCII to PostScript conversion, carriage return insertion, and scrambling. By setting a particular variable to 1, this option is then turned on and a 0 turns it off.
4.Create the LP= device used as a locking mechanism for contending print jobs.
touch /dev/spike.prn chmod go+rw /dev/spike.prn
5.Start the print spooler. lpc start hp
6.Print with the following syntax: lpr
