4.2. Dual-density bit image mode setting by ESC L + n

When the ESC (<1B>
H
) and L (<4C>
H
) codes followed by data n
l
and n

are
input, the printer’s operation mode is converted from Text to Dual-density Bit
Image.
The transfer sequence of bit image data is the same as with the ESC K (normal-
density bit image printing), but bit image printing can be performed in twice the
dot density in the horizontal direction as with the ESC K. In other words, bit image
data can be printed in 960 dot positions per line, thus permitting to produce denser
graphic data.
NOTE: Mixing of normal-density bit image with dualdensity bit image on a line is at your
option, as well as mixing with normal size characters in the text mode.
