Prints high density graphics
Prints a high density bit image of the number of dots specified by n1
and n2. The value of n1 + 256
×
n2 is between 1 and 420.
A maximum of 420 data bytes can printed in one line. Any data
exceeding 420 bytes is ignored.
After printing the bit image, the printer automatically returns to the
character mode. The relationship between the pins on the print head
and the data is the same as those shown for the previous bit image
code <ESC> “K”.
While printing a high density bit image, the horizontally adjacent
dots cannot be printed.
We will create the design below using a bit image.
First, since the volume of data is 30, n1 = (1E)
H
. If the data m1 ~ m30
is converted to hexadecimal, it appears as shown below.
Horizontal density is three times that of the bit image for <ESC>“k”.
(Compare the print samples.)
