Introduction
What is a TROY Port Monitor? The TROY Port Monitor is a Windows-based application that manages and
configures all print data sent from your Windows application to your TROY Security Printing Solution.
Essentially, when you initiate a print job from your Windows application, the raw print data is formatted to fit the
printing parameters of the selected TROY printer using the corresponding MICR printer driver installed on the
host computer. The formatted print data is then sent to the Windows print spooler, a temporary holding area
where all print jobs reside until all previous print jobs have been completed. The TROY Port Monitor receives
the formatted print data from the Windows print spooler (before the print job is sent to the printer), manipulates
the print data as needed (via preset and/or user-defined commands), and then sends the modified print data on to
your TROY printer. In this way, the TROY Port Monitor allows you to embed additional user-defined data
and/or print commands (data encryption and TROY security commands) into the print data stream generated by
your Windows application before it is sent to your TROY printer. Once the TROY Port Monitor is set up and
configured on the host computer, all this functionality takes place in the background without the need for any
additional user intervention.
By using the TROY Port Monitor to print to a TROY Security Printing Solution, certain printer feature settings
can be temporarily changed during a print job. Features that offer this job-by-job configuration flexibility are
known as job-related features. When the print job has finished, the TROY printer will automatically return to the
original default feature configuration set by the administrator.
