described on the basis of fig2 a data stream of a print application is composed for example of jsl data job source library data in the xerox format as well as of resource data such as fonts fnt images img logos lgo and form data frm these resource data are also printer language specific i e specifically for the aforementioned xerox print data stream data that are played into the i filter input or conversion filter at the input side input from a magnetic tape a diskette a host computer or a hard disk are separated therein according to jsl data variable xrx print data and resource data the jsl data are copied into the job source library jsl subsequently compiled by xerox data library xdl and deposited in the cobol isam 1 dparm datafile before the x filter interprets them for print conversion within the print control computer the resource data are deposited in a resource dataset rds after the conversion by the xerox resource converter xrc in the x filter the data of the print data stream are recompiled to form a shared job deposited as print dataset pds and compiled via the module sps siemens print server into an ipds data stream intelligent agent printer data stream that can be read by the printer 12 insofar as function calls for graphics or the like ensue within the xerox print data stream this ensues in the xrx function interface that is associated with the x filter fig3 shows how these processes can be program internally controlled a central component part of the printer control is a communicator that has intercourse with its environment via the global.
