Network printing from VDM does not work!

Have just upgraded a dozen computers to win 2k, for a new software package we wanted to run called Pentagon 2000. It is currently a DOS application, but will soon be SQL. But, right now we can’t print from P2000 across the network. I can print from a DOS box, but not from Pentagon it says “Printer not accepting data.” Have checked with net use, looks good… HELP
