Using an installation-provided filter

For each type of data format, you can specify the name of an associated filter. A filter is a program that can inspect and modify data. When you specify the name of a filter for a supported data format in a printer definition, the filter is called when the data format is detected. IP PrintWay™ can call the associated filter (a filter is called only once for each data set):

• IP PrintWay extended mode calls the filter before it transmits the data set to the printer.
• IP PrintWay basic mode uses the filter only if you also select the Resubmit for filtering field. IP PrintWay basic mode resubmits the data to Print Interface, which calls the associated filter program.

Your installation can write its own filter program, either a DLL filter or a UNIX filter. For information about how to write a filter, see z/OS Infoprint Server Customization.
