The Paris Spooler is capable of launching and managing multiple formatting
engines.

When a job arrives for processing, the Spooler automatically searches for an
available formatting engine and assigns the job accordingly.

For example, if you had the Spooler running with 2 engines launched and a 1000
page job arrived followed by a 2 page job, the first job (1000 page) would be
assigned to one engine and the following job would be assigned to the other
available engine. This means that the second job does not have to wait until the
first job is completed.

There is no upper limit to the number of engines launched by the Spooler, but
rather it is governed by the practical processing limits of the hardware platform.

When adding an Engine to the Spooler, an option is available in the View/Change
Engine dialog whereby you can link an engine to a particular printer.

Linking an engine to a printer is an advantage in situations where many small print
jobs are being printed to disk at the same time as normal print jobs. By linking the
printer and engine, the engine does not need to keep changing its ‘character’ for
the different printer types.
