Silicon Graphics POWER CHALLENGE User Manual page 83

Your serial printer must work in concert with the LP spooling system that
your Challenge deskside server uses. The LP spooling system allows you to
add or remove printers, and to change interface programs, devices, and the
system default printer. Be sure to read the documentation that comes with
your printer.
Use the following guidelines only as an example procedure for setting up a
serial printer.
To add a dumb printer to serial port 2:
1. Become superuser and change the ownership of the printer device file:
# chown lp /dev/ttyd2
2. Change the permissions of the printer device file:
# chmod 600 /dev/ttyd2
3. Edit the inittab file using vi or your favorite line editor, and confirm that
port 2 under "on-board ports" reads as follows:
# vi /etc/inittab
t2:23:off:/etc/getty -N ttyd2 co_9600 # port 2
4. Modify the line, if necessary, and reprocess the inittab file:
# telinit q
5. Configure the LP spooling system for your dumb printer:
# /usr/lib/lpadmin -pEPSON -vttyd2 -mdumb
6. Start the print spooler:
# /usr/lib/lpsched
7. Enable the printer to accept print requests:
# /usr/lib/accept EPSON
8. Activate the printer:
# enable EPSON
