When you print something in a Terminal service / rdp session with your Windows XP machine you will only find strange signs / symbols on the page you printed.
There is an simple solution for this:
# Close the remote desktop session.
# Search on a PC with Windows 7 installed for the file: “TsWpfWrp.exe” in the directory: c:\windows\system32
# Copy this file on the same location on the PC with Windows XP installed
Relog to the RDP session and try to print!
