Native Mode Spooler Reference Manual

Appendix C  Page Level Recovery and Checkpoints 

The native mode spooler (NMS) supports Page Level Recovery (PLR) and
checkpoints, which provide the ability to restart printing at any page of
the document due to device problems (such as power failure, paper jams,
running out of paper, ink, toner, etc.)  or a suspended spooler.

The Page Level Recovery and checkpoint functions recover spooler output
in different ways.  Which method you use is determined by the type of
device you are using.  Several devices support PLR, whereas only CIPER
protocol printers (i.e., the HP 256x series with HP-IB interface) support
checkpoints.  The following sections describe PLR and checkpoints, and
how to use them.
