• When bit image data have been input in excess of dot position of one line (432 dots) , the excess
data are discarded.
• d is bit image data, the bits subject to printing are taken as "1" and those not as "0".
[Caution] • When the values set in m (bit image mode) are out of the above range, the data following after n
is processed as normal printing data.
• After completion of bit image printing, printer returns to normal data processing mode.
[Compression procedure for mode 17 and 18]
A simple RLE encoding like this in PCX files is used. If two most significant bits of the byte are
set, the 6 LSB contain a repeat counter (1-63), and the next byte contains the data to be repeated. A
single data byte with 2 MSB set must be sent as two bytes.
13. ESC – n
Specifying/ Canceling Underline
[Code]
[1Bh] + [2Dh] + n
[Range]
{0 <= n <= 2}
[Outline] Specifying/canceling an underline.
• Types of underlines by
n
value are shown below:
0
Canceling an underline.
1
Specifying an underline for 1-dot width.
2
Specifying an underline for 2-dots width.
[Caution] • An underline is attached to the full character width. It is, however, not attached to the part having
been skipped by horizontal tab command.
• An underline is not attached to a 90°- right-turned characters.
