printer goes offline when remote printing is attempted through VPN and terminal server connection

I use Sonicwall Global VPN client to connect to our network and I also use TRICERAT SCREWDRIVERS software for remote printing.  This has always workd for computer except the one I will describe.  At another remote office we installed a Toshiba printer/copier and I installed the screwdrivers software and told it to spool the default printer.  After the VPN is established I login to the terminal server and I can see the local printer there to print to just like all the other computers at other offices I have set this up at.  When I click print the printer immediately goes offline and the user has to reboot the computer to get it online.  The user CAN print from their computer to the printer but not when the VPN is connected and they are logged into the RDS server.  Seems like a screwdrivers problem and not a VPN or RDS issue.  I don't have another printer in the office there to test if it is the printer.  FYI.  All these computer are not on a domain, they are in a windows 7 pro homegroup.

Is the SonicWALL set up as the default gateway on the printer?  Internally printers do not need a gateway so it is often left out, over a VPN it is required so that it has the return route.   That being said if not IP printing but rather a session printer it shouldn't matter.

Found out that it was 2 subnets with the same ip addressing scheme.
