[Samba] Printing - "lprm command" not getting executed

[Joel Hammer]

Here is what I used for one share. Looks like yours.

[Win4LinZ53]
	comment = Raw Printer for Z53
	path = /tmp
	create mask = 0700
	guest ok = yes
	hosts allow = 192.168.
	printable = Yes
	printing = lprng
	print command = echo %p %s >> /tmp/junkJ; /usr/bin/lpr -PWin4LinZ53 -J'%J' %s; rm %s
	lpq command = /usr/bin/lpq -PWin4LinZ53
	lprm command = /usr/bin/lprm -PWin4LinZ53 %j
	lppause command = /usr/sbin/lpc hold -PWin4LinZ53 %j
	lpresume command = /usr/sbin/lpc release -PWin4LinZ53 %j
	printer name = lp
	share modes = No

There is a file, /etc/lpd.perms, whose syntax is awful.
I have one line in mine:
DEFAULT ACCEPT
Other problems come to mind, mainly, permissions.
