How USB to parallel port works

A standard parallel port printer can be converted to a USB interface using a USB print cable. Driver Support After installation, you can virtualize one print channel through the conversion path in the USB environment.

For most engineers, the main obstacles in developing USB2.0 interface products are: to face the complex USB2.0 protocol, to write the driver of the USB device, and to be familiar with the programming of the microcontroller. This requires not only considerable VC programming experience, but also hardware (firmware) programs that can write USB interfaces. So most people gave up developing their own USB products. In order to simplify the complicated problem, Xi'an Datai Electronics specially designed the USB to parallel port module USB20D. This module can be seen as a USB2.0 protocol converter that converts the computer's USB 2.0 interface into a transparent parallel bus, just like a microcontroller bus. So within a few days you can complete the design of the USB2.0 product.
