The SPC record generates vertical space in the direction of the current<br />
font. Refer to Chapter 1 for a description of font direction. The space is<br />
generated just by moving the cursor; the logical function (see SLF) has no<br />
effect.<br />
1-2 2 Record Length The length of this record, in binary, including the record length<br />
field. For example, hex 00 06 specifies a record length of 6 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 07<br />
identifies the SPC record.<br />
5-6 2 Vertical Space An unsigned binary number that specifies the number of dot rows<br />
of vertical space to be generated. The range is 1 - 65535. The<br />
vertical space is generated in the direction of the current font. The<br />
current font is the last font specified in a previous record.
