Cannot redirect output to printer
If you redirect output directly to the parallel or serial port
and nothing happens or the system displays the
cannot create message:
If you configured your printer correctly
and you still cannot redirect output to it,
the problem is most likely a hardware malfunction.
Recheck the cables and port configuration and
consult your hardware documentation.
Verify that the device file for the port exists in /dev.
Make sure that this file is a device file and not a text file.
For example, use the following command to check lp0:
ls -l /dev/lp0
The output should look similar to this:
crw------- 2 bin bin 6, 0 Jun 13 1993 /dev/lp0
A regular text file does not include the ``c'' character
(for character special file)
at the beginning of the line.
Test the cable connection using a cable from a working device with
the same cabling requirements.
Print a file while the system is running under DOS.
If you can print a file under DOS but not under the UNIX system:
Verify that the port is configured correctly. See
``Port does not respond''.
If the port configuration is correct and you still
cannot redirect output to the port,
try using a different device name.
For example, for a parallel port,
use lp1 instead of lp0.
For a serial port, use tty2a instead of tty1a.
Pay attention to the
unit= message for parallel ports
on the boot screen or use hwconfig
unit=0 corresponds to lp0).
If you still cannot print using a different device name,
your printer may be defective; check the printer documentation.
If you cannot print from DOS, check the printer hardware configuration.
See the documentation provided with your printer.
