Note 1: Bit numbering follows the EBCDIC standard, with Bit 0 being the most
significant bit.
Note 2: If the Correlation ID field is not present (Byte 4, Bit 1 is 0), the data field starts
at Byte 5 rather than at Byte 7.
Note 3: Both positive and negative values in the data fields are allowable. Negative
values are in twos-complement form.
Note 4: Some bytes or bits in the data fields are reserved. The printer does not always
check the contents of these fields. However, it is recommended that such fields
equal the specified value (if one exists) or zero.
Note 5: The 1330 will not detect a condition where the specified command length (Bytes
0-1) exceeds the actual number of bytes received. If this occurs, the printer will
not process the command until it receives the specified number of bytes.
