Chapter 4. Record Formats
Set Relative Position (SRP)
Set Relative Position (SRP)
The SRP record contains X and Y values that set a new cursor position
relative to the current cursor position.
Byte Position Bytes Field Name Description
1-2 2 Record Length The length of this record, in binary, including the record length
field. For example, hex 00 0C specifies a record length of 12 bytes.
3 1 Cyclic Record Count A binary cyclic record count using modulo 256. Each record in the
job is counted, starting with hex 01 for the first record. The 255th
record is hex FF and the 256th record is hex 00. This count is used
to verify record sequence.
4 1 Control Code A binary code that identifies the record type. A value of hex 38
identifies the SRP record.
5-8 4 X Value A signed binary number that is added to the current X position of
the cursor to determine the new X position of the cursor.
Negative values are represented using the two's complement form.
For example, hex 00 00 00 08 specifies +8 dots and hex FF FF FF
F8 specifies -8 dots.
9-12 4 Y Value A signed binary number that is added to the current Y position of
the cursor to determine the new Y position of the cursor.
Negative values are represented using the two's complement form.
For example, hex 00 00 00 1B specifies +27 dots and hex FF FF
FF E5 specifies -27 dots.
