|Hi Manoj - how are you attempting to connect your laptop?|
You advise you bought a parallel cable (which requires a LPT port) but you also advised your laptop does not have a LPT port.
Have you configured Windows XP for your printer?
Google is your friend. If usb is involved, this may help:-
As a matter of interest, where are you located? I am in Hammersmith, West London.
Good Luck - Keep us posted.
