[Description]

Defines the character pattern (raster format) for the character code page in the work area.
  • x specifies the number of bytes in the horizontal direction.
  • c1 specifies the beginning character code for the definition, and c2 specifies the final code.
  • y specifies the number of dots in the vertical direction from the top.
  • d specifies the definition data (raster format).
  • k indicates the number of the definition data. k is an explanation parameter; therefore, it does not need to be transmitted.

[Notes]

  • This function works in user setting mode.
  • Characters in Hexadecimal: 80h – FFh / in Decimal: 128 – 255 in ASCII code can be defined.
  • If y, c1, c2, or x process a value out of the definition range, processing of this function is canceled.
  • Changes the data of the user-defined code page that is copied into the work area by GS ( E   <Function 7> .
  • 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 GS ( E   <Function 7> first.
  • 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.
  • GS ( E   <Function 8> can also define character data. It is recommended that either of the functions be used even if both functions are supported.
  • 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.
