Port Monitors

Once a device driver has converted an entire journal file into raw device commands, the file of converted commands is passed back to the spooler. The spooler sends these low-level commands to a monitor. A port monitor is a .dll that passes the raw device commands over the network, through a parallel port, or through a serial port to the printer device. Custom port monitors can be installed to support passing device data through other communication ports.

Use the following functions to work with port monitors.

Function Description
AddMonitor Installs a local port monitor and links the configuration, data, and monitor files.
DeleteMonitor Removes a port monitor added by the AddMonitor function.
EnumMonitors Enumerates the port monitors installed on a specified server.
