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 (PReS Connect document+data).
Triggers are used in two situations:
l When the server running PReS Workflow sends a PReS Connect 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 Data Capture and Trigger Implementation Guide as well as the PReS Connect 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.
Load balancing can only be used for jobs sent to Printer Queue output tasks and it only
applies when multiple queues are selected.
In the General tab of the Printer Queue Output Properties dialog box, you may select multiple
printers, and in the Advanced tab, you can set the load balancing options for the selected
printers.
