@chandana: I got together with one of the guys from IT and we tried out the printing. Everything works great when we print to the hard disk of the PC itself, but it doesn't seem to work with a network share. The person logged in to the PC has full access to the network share, and can open the folder, can add or delete files and so on. However the application doesn't seem to "see" the network share. We can set it up in the printing configuration as the destination, but the files just don't make it to the share.
Are we doing this wrong? Is this a firewall issue? Or is there a bug in the application?
