Do you have the User Manual?
If not:

Do verify that I have identified the correct manual.
That said more information is needed:
Specifically what is or is not happening?
How are you connecting the printer to the Windows XP computer?
Did you install the printer drivers on the Windows XP computer. (Drivers are software that allows a computer to communicate with a specific peripheral.)
What have you done or tried thus far to get the printer to print?
Any error messages, pop up windows, etc. on the computer? Any indicator lights on the printer?
