4. A method according to claim 1 wherein at least one of said input document data stream and an output document data stream comprising said output document data file is resource-structured and comprises a page description language data stream.
1. A method for enhancement with a print data processing computer of an input document data stream which comprises at least one input format formdef file as an advanced function presentation (AFP) format definition resource file (formdef) comprising format definitions and an input document data file structured in ranges and sub-ranges and containing variable data, comprising the steps of: in a control file defining finishing commands and enhancing the data stream with said finishing commands, said control file being generated by analyzing a data structure of the input document data file and mapping said data structure into said control file, and said finishing commands being automatically inserted into said formdef file which are invoked instead of original calls contained in the document data file; in the control file also defining document levels that correspond to at least one of the ranges and the sub-ranges of the input document data file, the document levels on which specific ones of the finishing commands are to be applied being defined independent of said data structure of the document input file, said data processing computer comprising a first computer program module providing a graphical user interface by which a user specifies said levels within the data stream; in the control file also by use of said graphical user interface the user also associating the finishing commands with the levels, and registering which finishing commands are executed in which levels; in the control file also associating a first of the finishing commands with one of the ranges and associating a second of the finishing commands with one of the sub-ranges; and using the control file, input format file, and the input document data file, with said processing computer automatically generating and outputting by a second computer program module to a printing device for creating a printed document an output format file as an advanced function presentation (AFP) format definition resource file (formdef) that contains the finishing commands in callable groups, the output format formdef file being provided with modified medium maps relative to the input formdef file, and an output document data file containing the variable data and group calls associated by at least one of range-by-range and sub-range-by-sub-range.
