[General] Interface between parallel port and USB printer using microcontroller

[sandeepanand.62]

Dear All,
I am working on a medical equipment. This device consists of a sensor , a few micro switches and some ports. One of the micro switch is to print the data from sensor. The printer used here is dot matrix. So the port to connect it is parallel port. I have to connect a USB printer to this device. I can add some extra hardware to make the data from that board to USB compatible. If anyone knows about this please suggest me some ideas. I need the micro controller name (if needed for this) and circuit and the code. please help me......

Regards,

Sandeep

Thanks for all your reply...
The printer output needs both text and graphics. I already searched for the USB host. But I want to know whether the data given to the dot matrix printer holds any printer commands ? Will it support the USB printer ?

yes it does run it as EPP(enhanced parallel port)
for more details about it (beyond logic .org)
