StreamServe Print Processor

The Print Processor enables you to convert documents from Microsoft Office applications into LXF (Layout eXchange Format) files. You can then, if required, send these files to the StreamServer via an input connector using the HTTP protocol.

A print processor is a component of the Windows printing environment that handles spooled print jobs. The Print Processor receives Windows EMF (Enhanced Meta Format) spool files from printer drivers, and if specified, converts the spool files to LXF format. It then sends the data to the StreamServer or disk file.

This means that you can print overlays from external Windows applications to a printer that is configured to use the Print Processor, and deliver the resulting overlays to StreamServe in a format that the StreamServer can work with.

When an EMF spool file is sent to the StreamServer, the EMF to LXF filter can be used to convert the file to LXF format on the server side.

Example 1

Using the Print Processor with a Job Resource output connector

When you create an overlay using an external tool, you can use the Print Processor to convert the EMF file into an LXF overlay. The LXF overlay bypasses the StreamServer and is sent directly to a Job Resource output connector. A Job resource is created, in which the LXF overlay is temporarily stored. The LXF overlay can then be called from a PageOUT Process and added to the processed output.

Currently, a Job Resource output connector can only handle LXF overlays to be used in a PageOUT Process.
