Specify left margin is 0, and the horizontal position to a position that is a multiple of 8, and
specify the horizontal size of the graphic to the dot which is the multiple of 8.
(Example: the left margin = 0, horizontal position = 8, 16, or 24, or 32 etc., (x
L
+ x
H
× 256) = 64, or
128, or 256 etc.)
Specify the scaling to the original size (
bx
= 1,
by
= 1).
Specify the size of image data not to exceed the current print area.
A graphic that exceeds the size limit of (y
L
+ y
H
× 256) can be printed by a repeated use of the
combination of this function and <Function 50> of this command. In that case, the performance
may be best when the vertical size is specified to [59 (y
L
+ y
H
× 256) 246 (reference value)] by
this function. However, the value is only a reference value. The most suitable vertical size
depends on the specifications of the PC, the interface used, and other factors.
If using a serial interface or if the time of processing this function cannot be shortened when
processing the above-mentioned item, the printing result may include horizontal stripes. In this
case, transmit the graphic data specified within the maximum range of (y
L
+ y
H
× 256) one time to
prevent the horizontal stripe.
Specify the horizontal size of graphics as 64 dots and horizontal single × vertical single size
settings
[(y
L
+ y
H
× 256) = 64, bx = 1, by = 1] when setting dot density to [180 dpi × 180 dpi] with Function
49.
The dot density and maximum print area are the same as Function 69. See the model information
of Function 69.
