„s“ is the number of bytes in vertical direction – always three.
„n“ indicates the start character code and „m“ indicates the end
character code. To define only one character set n=m.
„a“ is the number of dots in horizontal direction.
„Di“ is the data to be defined. The number of data for each symbol is
s x a. Each symbol defines with three bytes of data in vertical
direction followed by the next three bytes that define the next
one-dot column, etc.
The downloaded font is cleared by ESC @ and ESC _ commands
and when the printer is switched off.
[Default] The default downloaded font is equal to the default character set.
However the downloaded font is not reset when the code page is
chaged, thus it remains the same as the previous code page.

dis the data that defines the symbols. Every FontA symbol consists
of 48 bytes while every Font B symbol consists of 16 bytes.
A Font A symbol is defined left to right, top to bottom, two bytes for
each horizontal line, as only the four most significant bits of the
second byte are used. Every bit denotes one dot. A bit set to ‘1’
means black dot. The most significant bit is the starting.
Every horizontal line of Font B symbol consists of one byte, as the
ninth point is always white. The most significant bit is the starting.
The user-defined characters are kept after printer off.

{k = n1 + 256 X n2 (m = 0, 1)
{k = (n1+256 X n2) X 3} (m = 32, 33)
[Outline] According to the number of dots specified in n, n2, specify the bit
image of mode m.
• The total number of dots printed in the bit image is equal to
n1 + (256 x n2).
• When bit image data have been input in excess of dot position of
one line (384 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”.
• The bit image modes specified by m are shown as follows:
[Range] {m = 16, 17, 18, 20 bit image mode }
{0 <= n <= 40h}
{0 <= d <= FFh}
{k = n * 24 * 48} (m = 16)

{k = n * 24 * 48} (m = 20) { After decompression }
{0 <= a <= 24 (Used only for mode 18.)}
{f = 0 (Used only for mode 18.)}
[Outline] In these graphics modes is sent a graphics block with variable width
n*8 dots and height 24 dots for modes 16,17 and a dots for mode 18. In
mode 17 data is compressed, and the bytes count specified is before
the compression. In mode 16 the same data is without compression.
Mode 20 is similar to mode 17, but every byte is mirrored before putting
in the print buffer (bits 0 and 7, 1 and 6, 2 and 5, 3 and 4 change
places). All modes are high resolution (203 x 203 DPI).
•When bit image data have been input in excess of dot position of
one line (384 dots) , the excess data are discarded.
•dis 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.
Vertical Direction Horizontal Direction
