Local Apps and Network Printing

[M Rathburn]

Edubuntu 8.10

I have an environment set up with applications such as Firefox and Adobe
Reader working smoothly running as a local app on diskless thin clients that
PXE boot.  However, I've run into a pickle with network printing...

Our printers are on the network and use direct socket printing (port 9100).
On the Edubuntu server the printers are configured and working great - if
you're not running a local app (ltsp-localapps).  If you're running as a
localapp, you don't get any printers.  So I installed CUPS into the thin
client chroot, and that actually works also, pending you don't log out after
configuring a printer (via https).

What is the best method for printing to network printers when running
applications as local apps?  Should whatever is in /etc/cups just be copied
over to /opt/ltsp/i386/etc/cups and update the image?  I've actually tried
that, but still don't see the list of printers in the Printer Dialog Box - I
suspect there's some Gnome applet update or something that needs to be
updated (?).

Or, is there an alternative method such as samba shared network printing or
something that could be set up in lts.conf/wherever?

Thanks.
