DOCUPRINT IPS SOLUTIONS GUIDE D-1
D. D AFP print flows
This appendix shows the AFP print flows for the different
environments supported by PSF. These print flows apply to both PSF
and the DocuPrint IPS printers.
Mainframe data flows
In the mainframe environment, you may install PSF in three
operating system environments: MVS, VM, and VSE. These
operating systems may run on either a System/370 or System/390
mainframe. The following sections describe the AFP print flows for
each environment.
MVS print flow
1. JCL is submitted to JES.
2. JES receives the job, then prepares and schedules the job for
processing.
3. JES passes control to the operating system for job execution.
4. Output is spooled to a JES spool file.
5. PSF acquires the job from the JES queue.
6. PSF identifies and retrieves any necessary AFP resources
stored on DASD. PSF then composes the data stream to IPDS.
7. PSF directs the output to the printer. The IPDS printer then
prints the data.
When PSF is finished, the job is purged from the JES queue.
MVS print flow for a remote printer via PSF/2
1. JCL is submitted to JES.
2. JES receives the job, then prepares and schedules the job for
processing.
3. JES passes control to the operating system for job execution.
4. Output is spooled to a JES spool file.
5. PSF acquires the job from the JES queue.
6. PSF identifies and retrieves any necessary AFP resources
stored on DASD. PSF then composes the data stream to IPDS.
7. PSF directs the output to PSF/2 via VTAM. With PSF DIRECT,
the document is routed directly to the printer and not spooled on
PSF/2.
