When Infoprint XT converts a Xerox job, it builds a custom form definition from information that it derives from certain non-printable resources for the job. It then imbeds the form definition inline, in the Advanced Function Presentation data stream that it generates. For other programs, such as IBM® Print Services Facility for z/OS, to use the inline form definition, you must omit the FORMDEF parameter or include a FORMDEF=DUMMY parameter with your job. This applies to any of the job submission methods that invoke Infoprint Server and its components. If you specify any external form definition name, your printed results are unpredictable.
