Terminal Servier Barcode Printers

I am trying to find a barcode printer that will work with Microsoft
Windows 2003 Terminal Server. Workstations are either WinXP Pro or
Win2K. We are using Vantage 6.1. Have Zebra LP 2844 and have not
sucessful with Zebra Tech Support or Epicor Tech Support. Can get
loaded but it takes anywhere from 2 to 5 mintues per label to print.
Using a variety of laser printers which print almost instantaneously.

Any help would be greatly appreciated.

Thank you.
