A job can be used to produce a printed document by first processing it with a digital front end (DFE) which then sends printing information to a marking engine. A job has required functionality and a DFE has supplied functionality. When the supplied functionality does not include the required functionality, the job must be modified or abandoned. When using certain DFEs, the job can be modified to include programming data. When processing the modified job, the DFE gains functionality through changed programming. The DFE then has sufficient functionality, which contains the required functionality, that it can process the modified job.
