About This Appendix

The IBM 4247 Printer implements a subset of PPDS. The environment in which the
printer data stream processor operates is described below.
If you are using the PPDS data stream commands, you use the commands in this
appendix, as well as those in Appendix C. Native 4247 Commands.

Print Job Processing

There are no PPDS controls that explicitly define print job boundaries. A print job for
the 4247 is established by the host system and consists of any set of related print
objects. A print job could be as short as one character or could be many pages
long.
