3. Release the buffer.
The left margin will be rounded down to a factor of 8. For example, if the
margin = 74, the logo starts at 72.
Retries are not attempted on print errors.
Valid at the beginning of the line only.
When printing in the document station, a line feed command must be sent
to advance the paper past the last line of the logo.
If the parameter d, w, or h is out of the defined range for this command, the
command is discarded and the remaining data is processed as print data.
This command will increment status byte 6.
If this message is printed on a regular basis, consider downloading it to

The data buffer in the Model TI3 and Model TI4, which is 16 KB, can be
used for signature capture.
