jaydeep,

While that might be possible using the Parallel Port module it is tricky and I'd not recommend driving a motor from the Parallel Port as it was not built to do so. I'd recommend getting a servo controller or a motor controller (see sabertooth) which will use serial or USB to communicate to the PC. It also isolates the motor power system from the PC which can cause damage if you get too much feedback from the motors.

Ok, have you tried to connect the parallel port pins to Enable, D1 and D2 lines on the l293d? Seems like that should work. What issues are you having?

Also note that you will need the inpout32.dll in order for the Parallel port module to work (its in the docs).

Or just download it from

http://www.logix4u.net/

You should then be able to use the Parallel port module to switch on certain pins that are connected to the l293 in the correct way. See

http://www.solarbotics.com/assets/documentation/kit10.pdf

page 9 for what those pin combinations should be.
