Trying to remotely get/change a Default Printer registry value for the currently logged on user

When I run the following command I get a different value than what I see if I manually browse to the registry key as the logged on user...

psexec -u workgroup\xxx -p xxx \\7040-xxxx -i 4 cmd (reg query "HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows" /v Device)

tried -i (by itself, or 1, 2, 3, 4 for testing)

or if I try:

psexec -u workgroup\xxx \\7040-xxxx -i 5  RUNDLL32 PRINTUI.DLL,PrintUIEntry /y /n "Adobe PDF,winspool,Ne03:"

I get "Operation could not be completed (Error 0x00000709), double check the printer name and make sure that the printer is connected to the network."

Thank you!
