Hi I just got this Idea for making a homemade LCD

I wanted to know if I could use a USB to printer Cable (adapter) to connect an 20x4 LCD to the USB port?

The adapter was taken from a HP printer which was damaged... so it has one USB conector and a 36 pin male conector from the back of the printer...

Since the adapter has a converter inside de parallel port casing I was wondering if this can be done?

Thanks!

This has been suggested many times before, but never have i heard of anyone getting it to work.

Actually...

What you have ther might not even be a USB to Parrallel converter, it might just provide a USB to processor link right to the Printer CPU. You would have to play with it to workout whether you can get anything out of the Centronics connector.. which personally I doubt.

Let us know how your testing goes.

You are right...the adapter gives USB printer support, but does not act as a second serial nor printer port...

The chip in charge of doing the interface is an Agere Uss720, which I plan to use, maybe without plug and play circuitry of the adapter, but only the single chip.

But I don´t know much about driver programing; and I will need something like that...

The other idea is to use the agere chip to interface temperature sensors, but that´s another story...
