[Function]
Registers download characters to the specified character code.
Specify 1 row of data with 1 byte of 1 to 8 pins, and 1 byte of 9 pin.
It is possible to specify the ON dot up to 1 to 9 pins in the vertical direction. However, it is prohibited to specify
the ON dot continuously in the horizontal direction.
A maximum of 10 download characters can be registered for 7 x 9 and 9 x 9 fonts.
The range of the location to write download characters is specified by n1 and n2. When the registered
character is 1 character, n1 = n2.
If one has been already registered to an address, it is overwritten.
This command registers download characters independent to each font.
Indicates the relationship of the character pattern and the print head (see figure below).
Definition data (d1 to d7) set the bits that correspond to the dots to print to "1," and the bits that correspond to
the dots that are not printed to "0."
Even if ESC @ (command initialization) is executed, the registered download character is not cleared.
This command is effective only a font other than the Thai font is selected as the character code table.
(Composed of vertical 2 byte when using the Thai font.)
