Many lab instruments use the GPIB. The handy GPIB Screen Saver is a USB screenshot saver for all GPIB instruments. The LM3S9B96 microcontroller, with its USB host interface, has more than enough resources to make retrieving screenshots easy. The compact design includes a GPIB 25-pin connector. The LM3S9B96 is connected to the GPIB lines without a level shifter or buffer.
