2. Header 2
Header 2 is the 1 byte length information transmitted from the second byte of the auto status.The table below shows
the composition of the Header 2.
Header 2 represents the auto status version (called automatic status version below) using bit 1 to bit 3 and bit 5.
For reference, the table below shows the relationship of actual version bytes and the Header 2.The auto status version
will be used as new information is added to the printer status bit positions that were empty, by adding new functions in
the future.
When the host does not control the auto status version, it is acceptable to ignore Header 2 received.
