Triggers
In PlanetPress 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 Connect document+data).
Triggers are used in two situations:
l When the server running PlanetPress Workflow sends a PlanetPress Connect document
along with the data to the printer, it adds a trigger before the document
(trigger+document+data).
l When the server running PlanetPress 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).
PlanetPress 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 Data Capture and Trigger Implementation Guide as well as the PlanetPress
Connect User Guide.
Load Balancing
PlanetPress 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 printers capacity and speed.
Load balancing can only be used for jobs sent to Printer Queue output tasks and it only
applies when multiple queues are selected.
