3. Send the odd dot plot control code ENQ (05 hex) and a second line of data, followed by a
line terminator.
a. A line feed (0A hex) used as the line terminator causes the contents of the buffer to
be plotted and the paper advances a single dot row, based on the vertical density of
the current mode. A CR (if CR = CR + LF is configured) may also be used with the
same result.
b. A form feed (0C hex) used as the line terminator causes the data bytes to be plotted
and the paper to advance to the top of the next form.
4. Regardless of which line terminator code is sent, the printer will default to the previously
selected print mode unless further plot control codes are provided with the data.
NOTE: Failure to adhere to this format may cause unexpected results.
