Bit Image Density
Bit image graphics may be printed in different dot densities. Dot densities are selected by conĆ
trol code:
D Control code ESC K selects the Single Density Mode.
Single Density bit image graphics in the Data Processing print mode are printed at 60
dots per inch (dpi) horizontally and 72 dpi vertically. In the Correspondence print
mode, the horizontal dot density is 90 dpi and vertical dot density is 96 dpi. In the
High Speed (HS) mode, horizontal dot density is 60 dpi and vertical dot density is 48
dpi.
D Control code ESC L selects the Double Density Mode.
The Double Density mode prints up to twice the number of dots per inch horizonĆ
tally in the same space as used for Single Density. The vertical dot density remains
