Connecting a Parallel Printer
73
3. Connect the other end to the parallel printer. Be sure you have
confirmed pin and signal compatibility before making the connection.
(See Table 4-7.)
Caution: Before plugging the printer into either a 110 VAC or a 220 VAC
outlet, be sure that the electrical rating on the label is in either the
100–120 VAC or the 200–240 VAC range, whichever applies.
4. Turn on the printer before restarting your system.
Restart the system or continue with other peripheral connections as needed.
To enable the serial port on any optional additional IO4 boards, enter the
following as the superuser:
# cd /dev
# ./MAKEDEV plp
The MAKEDEV command checks the system’s hardware configuration and
makes parallel port device nodes for all possible ports.
Your parallel 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 parallel printer.
Use the following instructions only as an example procedure:
1. Become superuser and configure the LP spooling system (the 03 in
-vplp03
represents the Ebus slot where the IO4 board is):
# /usr/lib/lpadmin -pTekprinter -vplp03
2. Start the print spooler:
# /usr/lib/lpsched
3. Enable the printer to accept print requests:
# /usr/lib/accept Tekprinter
4. Activate the printer:
# enable Tekprinter
