I've made a control system for prints with samba 2.0.7 that check
against users to see if they are allowed to print and if they are under
their day/year quota.
The set of scripts (bash) report also backed to the user if the printing
has been allowed and also their actual quota.
All works fine using postscript drivers (from Adobe) and standard lpq
daemon.

They key in sending back information to hosts is:

the samba print command is set as follow:
print command = /usr/local/samba/lpquota/lpruserwrap %p %U %s %m
lpruserwrap is a setuid C program that's used to call a bash script
(rember that print commands are executed as user) and the printer name,
username, printjob filename and machine name are passed to that script.

It take care of converting files (strip "\r" to use redhat ps filters)
and check quotas.
and then send back messages using smbclient:
cat message.txt| smbclient -M $machinename  ($machinename is taken from
%m)

bye,
Simo.
