Port Monitor

The port monitor is responsible for transmitting data to the printer as well as checking status of the printer.

A port monitor is required to support a minimum set of functions in order to function properly.

Windows has 2 port monitors that are included: The local port monitor, and the TCP/IP port monitor.

The local port monitor has no configuration options, and can send data to parallel ports, serial ports, network shares, as well as the FILE: port.

The TCP/IP port monitor is configurable and can send to network printers that support LPR or RAW protocol.

There is nothing stopping a port monitor from being a language monitor also. As a matter of fact a port monitor may also report itself as being a language monitor, and the same minimum set of functions is required for both types of monitors.

Virtual Port Monitor works as a Port Monitor.
