hi,
Well done!.
Download from a Google, the Pinout for the Printer connector.
It will give you the port addressess and which pins are which. example: 378, 379 and 37A.
Its important you get this port pin info, you will need it.
No, the pins are not 'powerful' enough to drive motors or relays, [try a LED]
Thats why you need the PCB I keep on about, you will need to put transistors and other components on, if you want to drive motors.
Do you have a dc power supply, say about 12Vdc, you will need something to power your motors.
Let me know when you have the pin outs.
