This node collects monitoring information about processing of
production print requests. These are output requests required for
smooth production operation (such as documents). We recommend you print
these output requests locally.
STYLE S_DOCUS1
To classify the output requests, we recommend you assign classes to
both the spool servers and output devices. By using spool servers
configured for different types and priorities, you can better control
output requests.
