GS *
Function: Define downloaded bit image
Code ASCII: GS * x y d1…dk
Code HEX:
0x1D 0x2A x y d1…dk
Range: 1 ≤ x ≤ 80
1 ≤ y ≤ 64 (1 ≤ x × y ≤ 5120)
0 ≤ d ≤ 255
k = x × y × 8
Description: Defines a downloaded bit image.
• x specifies (x × 8) dots in the horizontal direction, and y specifies (y × 8)
dots in the vertical direction (see notes).
• d indicates the bit image data.
• k indicates the number of the definition data. k is a parameter for an
explanation; therefore, it is not necessary to be transmitted.
Recommended
Functions:
It is recommended that downloaded graphics function (GS (L / GS 8 L:
<Function 52 > and <Function 80 > ~ <Function 85>) be used because it
offers the following additional features:
• Multiple number of logo data and mark data can be specified.
• Data control by key code is possible.
• Redefining or deleting the same data is possible.
• 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:
• Pixel data are arranged column by column. For each x, 8•x columns are
needed (if y = 1, 8 bytes are necessary). For each y, 8 vertically dots will
be defined.
• Data (d) specifies a bit printed to 1 and not printed to 0.
• The downloaded bit image is not defined at the default.
• Once a downloaded bit image has been defined, it is available until
another definition is made, ESC & or ESC @ is executed, the printer is
reset, or the power is turned off.
• A downloaded bit image and a user-defined character cannot be defined
simultaneously.
• When this command is executed, the user-defined character is cleared.
• When ESC & is executed, the user-defined character is cleared.
• The downloaded bit image is printed by GS /.
