HP (Hewlett-Packard) PCL 5 Printer User Manual


 
If more than eight replacement (delta) bytes are needed,
additional command byte/replacement bytes may be added,
as shown below:
?
*3m#W [(Command Byte)(1 to 8 Replacement
Bytes)][(Command Byte)(1 to 8 Replacement Bytes)]. . .
In the command byte, the upper three bits identify the
number of replacement (delta) bytes (which can be 1 to 8
bytes). The lower five bits identify the location the
replacement bytes are to be positioned. This position is
identified as the offset, or the number of bytes from the
treated byte. For example, if there are 5 replacement bytes
and the offset is 7, then the replacement bytes replace bytes
7, 8, 9, 10, and 11 (the five bytes beginning at byte 7 from
the seed row).
If there is more than one replacement in a row, the second
offset is counted from the next untreated byte in the row:
the first byte following the last replacement byte.
