I'm working on an updated version that includes stuff like setting up a printer by default, providing a choice of lab or developer build (extra apps, no ldap login).
I've got the printer going by creating a /etc/cups/printers.conf file with info on the printer (make, model etc.) and putting a pre-made PPD at /etc/cups/ppd/HCMC.ppd. Finally, printers.conf needs to be chgrp'd to group "lp" and the cups service needs to be restarted.
I'm now working on making it a bit more informative (echos out what is about to happen, provides choices etc.)
