Auto Increment Extension
Specifies that the print file extension should be increased automatically. To use this property the default extension must be a numeric value, such as 000.
Note: This is legacy functionality. A more modern approach is to use an extension representing the file format, such as .pdf or .hprtl, and include the <autoInc> variable in the File Name property.
Note: This property is only valid for the Print dialog and not for Print Organizer. Print Organizer obtains its file name from the Output File Name Expression dialog.
