Bit Image Density

You can print bit image graphics in different dot densities. To select dot

densities, send the appropriate control code to the datastream.

Single Density
Single density bit image graphics in the Data
Processing print mode (Mode 2) are printed at 60
dots per inch (dpi) horizontally and 72 dpi verti-
cally. In the Correspondence print mode (Mode 1),
the horizontal dot density is 90 dpi and vertical dot
density is 96 dpi. In the High Speed (HS) mode
(Mode 3), horizontal dot density is 62.5 dpi and
vertical dot density is 64 dpi.
ESC L
Double Density
The Double Density mode prints up to twice the
number of dots per inch horizontally in the same
space as used for single density
. The vertical dot
density remains the same as in the single density
mode. Double horizontal density requires twice the
number of input data bytes to print the same length
line as for Single Density. Printing double density
reduces the printing speed by half. If each 1 or true
bit is plotted, the result is a bit image plot of the
ASCII character “A.”
