With the Paris system you are able to create a Port Monitor that sends its output to
a temporary disk file allowing you to direct the output from the normal Windows
95/NT4 spool system into the Paris Spooler. The disk file is then treated as normal
input for the Paris Spooler.

The advantage of this approach is that the actual source of the input data is totally
removed from Paris. As long as the data can be delivered into the Windows
95/NT4 spool system then Paris can ‘intercept’ it.

To fully appreciate the benefits of the Port Monitor, it is critical to understand the
role of the ‘Print Providers’ in the Paris system as they determine what type of data
is delivered to the Spool system.

The role of Print Providers
Most Windows applications such as Word or Excel use GDI to send data into the
spool system. GDI always sends data to a printer driver, which in turn delivers
formatted data into the spool system (as internal spool files). These spool files
always go to a port monitor for final delivery to the print device.

Other print providers, such as LPD or the DOS copy command, do not use a

The Paris Port Monitor is able to receive any data files sent into the Windows
95/NT spool system. However, it makes no sense to send GDI files as they are
already formatted and therefore cannot be processed by Paris. As a result, the Port
Monitor is only useful if the print provider used avoids the Windows print driver
(that is, it is not GDI based). This can be achieved by directing the flow of data
through the system as follows:

Data enters the system via a third party provider.
2.
The data is stored in a temporary spool file.

This file is then redirected to a temporary disk file via the port monitor.
4.
The engine processes the file and delivers output to the configured
destination.
