Hi all,
I have to differentiate between a USB mass storage device and a USB Printer?

Issue i am facing is all the USB printers now a days come with an inbuilt memory / memory slot.
So becomes quiet intriguing to differentiate that this is a USB Printer and not a usb drive.

I need help on how to appropriately differentiate that the USB plugged in is a USB printer.
Code help would be great.

Thanks

The memory of such USB-Printer is visible as usb drive. So you see 2 devices: a printer and a drive.

You got to deal with it.

Hi,
you can use Usbprint.sys class driver that manages USB printers and usbstor.sys to manage USB mass storage.
for more information about these classes, use this link:
