Bit Image Density

Bit image graphics may be printed in different dot densities. Dot densities are selected by conF trol code:

DControl 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.

DControl code ESC L selects the Double Density Mode.

The Double Density mode prints up to twice the number of dots per inch horizonF tally in the same space as used for Single Density. The vertical dot density remains
