GS * x y [data] x × y × 8
[Designation] Define user-defined bit image
[Format] 1DH, 2AH, x, y, data 1 ... data x×y×8
[Valid limits] 1 x 255
1 y 48
x × y 1536
0 d 255
[Initial value] Clear
[Function] (1) Defines a user-definable bit image according to the number of dots specified in x
and y.
(2) The parameter x specifies the number of horizontal dots.
(3) The parameter y specifies the number of vertical bytes.
(4) The actual number of horizontal dots is determined by: x×8.
The actual number of vertical dots is determined by: y×8
(5) The parameter data indicates the bit image data. In this data, a 1 bit
corresponds to a dot to be printed. A 0 bit corresponds to a dot not to be
printed.
(6) The relationships between the user-defined bit image and printed data are as
follows:
(7)user-defined bit image (GS *) and Define user-defined characters (ESC &) can
be defined at the same time.
(8) User-defined characters (if any) are cleared when:
a. The Initialize printer (ESC @) command is executed.
b. The Define user-defined characters (ESC &) command is executed.
c. The define NV bit image (FS q) command is executed.
d. The power is switched off, or a reset signal is received.
