Oh, forgot to mention - if you are using CUPS instead of lpd and your other 
computers do not use CUPS, remote access is enabled by the following method:

CUPS installs without remote lpd access by default. To allow remote access 
from non-CUPS systems you need to enable a special daemon that emulates BSD 
lpr IO. Therefore you have to:

1. insert the following line into /etc/services:
	cups-lpd        515/tcp         spooler
2. enable inetd or xinetd to allow access:
	inetd:
		add do /etc/inetd.conf:	
		cups-lpd stream tcp nowait lp /usr/lib/cups/daemon/cups-lpd cups-lpd
	xinetd:
		create a new file in /etc/xinetd.d containing the following:
		....
		# default: on
		# description: The icups-lpd server accepts requests from remote lpd \
		#       clients.
		service cups-lpd
		{
		        disable		= no
		        socket_type		= stream
		        wait		= no
		        protocol		= tcp
		        user		= lp
		        id			= lp
		        server		= /usr/lib/cups/daemon/cups-lpd
		}
		....
		if you wish xinetd to restrict access to a specific domain, use the
		"only_from" directive, e.g.:
			only_from	= 192.168.0.0/24
 
I have used "cups-lpd" as the service name. if you wish, you can keep the 
service name as "printer" instead - your services file should already contain 
a "printer" directive....

Otherwise, CUPS is pretty much wide open. To restrict CUPS access, you need 
to edit the /etc/cupsd.conf file - see file for examples.
