USB HID-POS
Introduction
The HID-POS interface is recommended for new application programs. It can send up to 56 characters in a single USB
report and appears more efficient than keyboard emulation.
Features:

HID based, no custom driver required.

Way more efficient in communication than keyboard emulation and traditional RS-232 interface.
Note: HID-POS does not require a custom driver. However, a HID interface on Windows 98 does. All HID interfaces
employ standard driver provided by the operating system. Use defaults when installing the driver.
