IrLPT is part of the IrCOMM specification, and is also referred to as IrCOMM 3-Wire Raw. It deserves special mention because it is the mechanism by which legacy printing is achieved between devices and IrDA-enabled printers. Support on desktops is achieved through a virtual LPT port that maps to the IrDA port.
When an application or printer driver is configured with the virtual LPT port, infrared printing is enabled without changes to the printer driver or application. As with IrCOMM, IrLPT is intended for legacy support of existing applications.
Because of its importance for legacy printing, where applicable, IrLPT is required for devices seeking IrReady interoperability certification.
