Windows 7 - How do I verify a NET USE LPT connection

I am having problem printing across network from a dos program on a Windows 7 64 bit machine to a dot matrix text printer that is attached to a XP machine.
I have 5 other xp machines that use this same program and have had no problems. Just installed the Windows 7 machine and CAN print test page but not from the dos program.
we use the NET USE LPT2:\\BRAD\SERVICE /PERSISTENT:YES command

i've tried a number of things. one thing that I am seeing is that on all the XP machines when I go to Dos Prompt and NET USE, all the machines have one line (among others) pertaining to LPT2. It says Disconnected for Status, LPT2 for local and \\BRAD\SERVICE for remote.
on the Windows 7 machine this line is not there. I am wondering if It is acepting the command at all and wonder what I can do to verify that the LPT2 connection is actually made?

I have typed this command by hand on the WIN 7 machine and within a batch file.
When I enter it manually I get the System error 67 has occured error but I get that on all of them so this must be normal.

thanks
