LPR time-outs and retry periods
Some LPR programs wait only a limited amount of time to send their print files.
If you receive a timeout message from your host, the adapter was probably
printing a long job. You should retry the print job.
The adapter supports a finite number of active LPR connections at a time. If
more than this number of connections are attempted, the extra attempts will not
work. Many UNIX programs retry the print job after a specified amount of
time. If you want to use several active LPR connections, we recommend that
you set a short retry period so that print jobs will be sent until they are accepted.
Some UNIX systems may default to a 15-minute retry period. We recommend
that you use the lp-system command to set a shorter retry period for those
computers. You can also telnet to port 9000, then follow the instructions on the
screen.
LPSTAT and LPQ commands
Most line printer status (LPSTAT) commands work as usual with this adapter.
We recommend that you use the finger command to get the status of the printer,
rather than a line printer query (LPQ) command. Finger returns much more
useful information to you than the LPQ command.
If you need information about using finger to get the printer status, see “Using
Finger” on page 2-22.
Using telnet to add carrier returns or line feeds to all LPD print jobs
You can use telnet to change the LPD protocol so that it automatically adds
carrier returns or line feeds to all print jobs. You may find this helpful if you are
printing text files without graphics.
1 Type the following at the command prompt:
telnet ip.address -p 9000
where
ip.address is the IP address you’re using, such as 9.51.8.231.
2 From the menu that appears, select Set lpd options.
3 Follow the instructions on the screen.
