W2400 USB host interface board

I was asked if documents could be printed on this old model from a USB flash drive. I perused the PSG, and there is no mention of printing or scanning using a flash drive. However, it does have the USB host interface board option installed. Can somebody tell me what it is used for?

Ok, I found out it is for Bluetooth devices, usb keyboards and IC card readers.
