    It looks like a standard HD44780 display, 16x2 character with LED backlight, the pinout seems to be identical (first datasheet). 99% of character displays like this are hd44780 or at least are compatable (rip-offs basically). You can either hook this up to the parallel port as per normal, using just a printer cable, some wiring for the power to it (5v) - you may need a resistor for the backlight - look for a resistor near pins 15 or 16 (in series with). you will also need a potentiometer for the contrast adjustment.

    If you wish to connect it to USB or SERIAL you will need a controller IC - there are a couple about that use a PIC or AVR processor to take serial comms and output it to the LCD, it is not terribly hard and there is plenty of info about. If you want a cheap fix, try looking at LCD2USB for instance : http://www.harbaum.org/till/lcd2usb/index.shtml
    note that USB -> Parallel adaptors wont work as they immitate USB printing support and not an actual parallel port...

    Good luck,
    Alex
