How to use USB interface with Mobile operating systems

QUESTION
How do I use USB interface for SPP-R200 using Mobile operating systems?

ANSWER
The USB printer class driver provided with the Platform Builder by default is required.
USB Printer Class Driver is included in the PCL Driver Package, which is one of the device driver items of the Platform Builder.
Check whether USBPRN.dll file is in the Windows folder.
This package should be installed in order to set the LPT port when USB Printer Class performs PNP.
