[Default]

None

[Description]

Defines the downloaded bit image in the downloaded graphic area.
  • x specifies the number of bytes in horizontal direction as x bytes.
  • y specifies the number of bytes in vertical direction as y bytes.
  • d specifies the bit image data (column format).
  • k indicates the number of the definition data. k is an explanation parameter; therefore, it does not need to be transmitted.

[Recommended Functions]

This command is supported only by some printer models and may not be supported by future models.
It is recommended that download graphics function (GS ( L   /   GS 8 L: GS ( L   <Function 52> and GS ( L   <Function 80> – GS ( L   <Function 85> ) be used because they offer the following additional features:
  • Multiple number of logo data and mark data can be specified (except for some models).
  • Data control by key code is possible.
  • Redefining or deleting the same data is possible for each key code.
  • Selecting a color for printing is possible.
  • Defining data by raster format is possible.
  • The remaining capacity of the definition area can be confirmed.

[Notes]

  • Data (d) specifies a bit printed to 1 and not printed to 0.
  • The downloaded bit image is not defined as the default.
  • Once a downloaded bit image has been defined, it is available until another definition is made, ESC @ is executed, the printer is reset, or the power is turned off.
  • On some models a downloaded bit image and a user-defined characterESC & cannot be defined simultaneously.
    • When this command is executed, the user-defined character is cleared.
    • When ESC & is executed, the downloaded bit image data is cleared.
  • The downloaded bit image is printed by GS /   [obsolete command] .
  • The relationship between bit image data and print result is as follows.
