Chapter 4. Record Formats<br />
Page Length Requirement (PLR)<br />
Page Length Requirement (PLR)<br />
The PLR record specifies the page length requirement for the current RIP.<br />
Byte Position Bytes Field Name Description<br />
4 - 12 IJPDS Formats<br />
This record is optional. If a PLR record is used, it must appear with the<br />
PHR and FAR records before any font records, fixed file records, or the<br />
first document.<br />
Information in the PLR record can be used by the CD120 data station to<br />
reallocate page buffers for the current RIP and allow more efficient use of<br />
available memory. The maximum page length allowed is printer<br />
dependent. Some printers display a warning message if the page length<br />
requirements in this record cannot be met.<br />
1-2 2 Record Length The length of this record, in binary, including the record length<br />
field. For example, hex 00 08 specifies a record length of 8 bytes.<br />
3 1 Cyclic Record Count A binary cyclic record count using modulo 256. Each record in the<br />
job is counted, starting with hex 01 for the first record. The 255th<br />
record is hex FF and the 256th record is hex 00. This count is used<br />
to verify record sequence.<br />
4 1 Control Code A binary code that identifies the record type. A value of hex 3B<br />
identifies the PLR record.<br />
5-8 4 Page Length<br />
Requirement<br />
An unsigned binary number that represents the page length<br />
requirement for the current RIP in dots. For example, hex 00 00 0E<br />
00 specifies a page length of 3,584 dots. The range is 0 -<br />
4,294,967,295. The maximum page length is printer dependent.<br />
Note: Specifying a page length longer than the default length may cause less<br />
memory to be available for font storage.
