Triggers
In PReS Workflow, a trigger is typically a two line piece of PostScript code placed just before
the data. Triggers tell the printer to turn on PostScript mode and specify which document should
be used in the merging process (PlanetPress Design document+data).
Triggers are used in two situations:
l When the server running PReS Workflow sends a PlanetPress Design document along
with the data to the printer, it adds a trigger before the document (trigger+document+data).
l When the server running PReS Workflow only sends the data to the printer, because the
document is already present on the printer, it adds a trigger before the data (trigger+data).
PReS Workflow adds the trigger code automatically, but you may want to use custom triggers.
You would do this, for example, to use special printer functions. For more on custom triggers,
see the PlanetPress Design User Guide.
Load balancing
PReS Workflow offers various load balancing options to distribute the printing load and to make
the process faster and more efficient. Print jobs may, for example, be split equally among
several printers, or they may be split according to each printer’s capacity and speed.
