use userport. Install it then everything will work
IT is due to the security to the parallel port

access parrallel port in XP is restricted you have to use some types of drivers to use it.

Added after 1 minutes:

you can also use socket programming in .net framework
 

you can also try installing the totalio.sys driver from www.talkingelectronics.com
the driver is originally intended to enable the PIC programming software, IC-Prog to work in WinXP/2K. the program uses the serial port to program the PIC MCU. i think this should also enable other programs that directly access the serial and parallel ports to work. i'm not sure though...
