Job sent to an LPD input device with a Linux parent server

If the parent server of the LPD input device that you sent the job to is a Linux system, check these settings.

Make sure that the sending system is defined in the Hosts allowed to submit LPD jobs system property.
The default is to allow input from all systems.
Make sure that the LPD daemon is running.
From a Linux command line, enter:
```
ps -ef | grep ippd_lpd
```
If only the grep command is returned, the daemon is not running. Disconnect all LPD input devices defined on that server and then reconnect them.
If any LPD daemons that do not belong to RICOH ProcessDirector (for example, the Common UNIX Printing System [CUPS] LPD daemon) are running on the parent server, stop them.
