Remote printing utility using a raw bidirectional tcp connection

The rprint utility establishes a bidirectional raw TCP connection to a network printer, usually on port 9100. In case of PostScriptTM printers, rprint may be directed to query the printer for accounting and printer status information.

Although rprint can be used interactively, too, it is normally be invoked by an lpd input filter program.
