This is a six byte command which sets up the bit image graphics mode. The four bytes, n3n2nlnO,
are the ASCII presentation of the number of dot positions (horizontally) to be printed
in
graphics
mode.
For example, if 200 dot positions are to be printed, the command would be ESC S 0200 (decimal
data would be 27 83 4851 4848).
This six byte command would then be followed by 200 bytes, with each of the 8 bits controlling one
wire of the dot head. The density of the bit image graphics is affected by the character pitch currently
in force. (See Section 13-2.) The density of dots and the maximum number of dot positions per line
are defined in the following table.
