Function USBPrinter

USBPrinter is an attachment/detachment callback for RTUSB-32:

int USBPrinter(RTUDeviceHandle Device, RTUSBEvent Event);

Applications which need to support USB printers should register USBPrinter using RTURegisterCallback before any USB host controllers are registered. The printer driver will detect and handle up to 4 simultaneously attached printers.
