If the data in the user-defined code pages is not copied into the work area, this function is not available. In
this case, execute Function 7 first.
Definition data (
d
) specifies a bit printed to 1 and not printed to 0. The data to define a character is (
x × y
)
bytes.
When defining the character of the Font No. 10 (configuration: 9 × 17), only the MSB can be used in the
second byte for horizontal direction. When defining the character of the Font No. 12 (configuration:
12 × 24), only the upper four bits can be used in the second byte for horizontal direction. All bits can be
used when defining characters of other fonts.
Definition data (
d
) defines the
y
dots pattern from the top of the characters. When
y
is smaller than the
number of dots composing the built-in character, any remaining dots below are blank.
Deletes the character data defined in the same code.
Function 8 can also define character data. It is recommended that either of the functions be used even if
both functions are supported.
Definition area and printing results are the same in both functions, although Function 8 processes the
data in column format, and Function 9 processes the data in raster format.
The relation between the definition data and printing result is as follows.
Example: Characters composed of 24 × 12 dots (
x
= 2,
y
= 24)
The second bytes in the horizontal position use 4 bits of the MSB.
