Xerox 701P21091 manual Record structure, Multivolume processing

Specifying input parameters

Record structure

A record is arbitrarily divided into two portions: operating system and user.

•The operating system portion of the record contains information that is supplied by the host operating or spooling system.

•The user portion of the record contains information that is provided by the application or the program that is running on the host system.

The boundary between the two portions of the record is traditionally between the record length and the printer carriage control (PCC) fields. If there is no record length field, there is no operating system portion of the record. The PDL commands that define the components of a record are described in the “RECORD command” section of this chapter.

Multivolume processing

All multivolume reports that force the system to make multiple passes over the data are handled in the following manner:

•For each copy that is requested, a complete pass is made over the group of volumes that make up the current report. The system is forced to make multiple passes over the input data for multicopy reports that exceed the size of the print file. (Refer to your printing system online Help for information on the available choices for handling print file saturation.)

•If a multivolume report requires multiple passes, messages appear on the controller screen with instructions on which action must be performed next.

•Users with multiple volume jobs and multiple laser printing systems may wish to print each volume on a separate system. This requires that each volume be processed independently. (Refer to the VOLUME EOV parameter description, later in this chapter, for a discussion of this processing.)

•If a system rollover occurs while a multivolume report is being processed, the controller screen (as a portion of the recovery process) displays a message that tells you to click [Continue] to space forward to the recovery point.
