3.3.2 IrDA Interface
The hardware of T5 with infrared port printer is compatible
with IrDA1.1. IrCOMM protocol is one of the sub-protocol of
IrDA and widely used in portable devices. RAW-Ir
data
transmission mode can be connected to the devices with raw
infrared port for printing, while IrCOMM mode can be
connected to the devices with IrCOMM protocol for printing.
