None

[Description]

Defines the user-defined character pattern for the specified character codes.
  • y specifies the number of bytes in the vertical direction.
  • c1 specifies the beginning character code for the definition, and c2 specifies the final code.
  • x specifies the number of dots in the horizontal direction from the left. Any remaining dots on the right side are blank.
  • d specifies the definition data (column format).
  • k indicates the number of definition data. k is an explanation parameter; therefore it does not need to be transmitted.

[Notes]

  • Character codes from the alphanumeric characters in Hexadecimal: 20h – 7Eh / in Decimal: 32 – 126 can be defined.
  • The dot pattern is specified by data (d) in the horizontal direction from the left side. The definition data specifies a bit printed to 1 and not printed to 0.
  • The data to define a user-defined character is (y × x) bytes.
  • When the value of y, c1, c2, or x is out of the range, this command is canceled, and the following data is processed as normal data.
  • This command can define user-defined characters for each font independently. To select a font, use ESC ! or ESC M.
  • A user-defined character, download graphics, and downloaded bit image cannot be defined simultaneously on some printer models.
  • Once the user-defined characters have been defined, they are available until ESC ?, GS *   [obsolete command] , or ESC @ is executed; the user-defined characters are redefined; the power is turned off; or the printer is reset.
  • The user-defined characters are not defined at the default, and the resident characters are printed.
  • The relationship between the definition data and printing result is as follows.
  • Example: 
    Downloaded character definition consists of 7 × 9 dots. (x = 7, y = 2)
    (In the second byte in the vertical direction (d2, d4, d6, d8, d10, d12, d14), use MSB only.)
