The vPad Rugged 2 from Datrend could print directly to a printer, since this is a unit based on an android tablet, so if the printer has an application to print directly by Bluetooth or wifi you could do it

I have done this task with our Canon printers and border printers, also you could print labels for the devices that you tested

Hope this could help
