serial or usb to parallel

Is there an easy way to plug a parallel lcd into the serial port or usb via some sort of adapter. I like the parallel lcd's because of the fun colors ;-) Thanks in advance.

Chris

Would this work? :

it looks like it would. Of course i do not expect a guarantee, but have any of you had luck with this?

Physically and electrically, I would bet it could be made to work. But I would guess that the driver would be trouble, since it is probably only set up to do printer I/O, and not general purpose I/O.

Something like this:

Might work, and may have more open software documentation.

Chris,

what you are trying to do is technically possible, as you would need to build/aquire a RS232 to parrallel converter. This would require a microcontroller or similar to do the interfacing.

There are parallel to serial and serial to parallel IC's still on the market you can find common one in the 74Hx series in catalogs like Jameco - Digi-key - Mouser - JDR for a few cents to a couple of $$ and do the same as a micro-controller.
do a search on http://wwwgoogle.com on things like MP3 - LCD's
