Dan:

To answer your last question:

AP used ADAGIOv2

GL uses ADAGIOv3

v3 is where all the problems lie. Even getting it installed can be a problem.

If your client is on a LAN and the printer is on the network, then the correct printer driver installation is first on the server and then to use the server driver to install to the workstation (I believe but I'm an accountant, Patricia would be able to explain this better).
