Explanation:
From http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/admin-primer/s1-printers-sharing.html:

For pure Linux or Linux/UNIX environments, printer sharing can be controlled using the /etc/hosts.lpd file. This file is not created by default; as root, create the file /etc/hosts.lpd on the machine to which the printer is attached. On separate lines in the file, add the IP address or hostname of each machine which should have printing privileges:

falcon.example.com
pinky.example.com
samiam.example.com
pigdog.example.com
yeti.example.com

To have LPRng use /etc/hosts.lpd for access control, you must add the following line to /etc/lpd.perms:
ACCEPT SERVICE=X REMOTEHOST=</etc/hosts.lpd

This line must be added to /etc/lpd.perms before the line containing "REJECT SERVICE=X NOT SERVER". Failure to do so will prevent /etc/hosts.lpd from being recognized. Finally, restart the lpd printer daemon by issuing the command /sbin/service lpd restart (as root).
