Using the aopfiltr.so filter

For each type of data format that Print Interface supports, you can specify the name of an associated filter. A filter is a program that can inspect and modify data before Print Interface writes the data to an output data set on the JES spool. When you specify the name of an filter for a supported data format in a printer definition, Print Interface automatically calls that filter before writing data to the JES spool.

Infoprint Server provides filter aopfiltr.so, which prepares text data for printing on ASCII printers. This filter converts ASCII line-feed controls that are not preceded by carriage-return controls to carriage-return and line-feed controls (X'0D0A'). The X'0D0A' control is suitable for most ASCII printers.

Guidelines:

• Specify filter aopfiltr.so for the text data format in all IP PrintWay™ printer definitions except when you select the VTAM® protocol or the email protocol.
• Do not specify filter aopfiltr.so in a PSF printer definition.
