How PSF manages AFP printing

Figure 1 shows the basic components used to print data on AFP printers in an z/OS® environment. The PSF printer-driver program processes the MO:DCA-P, line data, and XML data streams from the JES spool, combines the data streams with resources needed to print the data, converts the data into Intelligent Printer Data Stream (IPDS), and sends the result to the printer. Because MO:DCA-P and IPDS are part of the same architecture, this is a very efficient process for applications that produce MO:DCA-P.
