Printers that use ports that do not begin with COM, LPT, or USB are not redirected in a Remote Desktop or a terminal services session
When you use Remote Desktop Connection or The Terminal Services Client version 4.0, 5.0, 6.0 or 7.0 to Connect to another Windows-based computer from a computer, your local printers are not redirected. As a result, your local printers are not available in the remote desktop or terminal services session.
For example, if your Windows XP-based computer has a multifunction print device using a DOT4 port or a wireless printer, it may not be redirected in a remote desktop session to a 2000, 2003 or 2008 Server based computer.
