6-Bit Dot Addressable Graphics
The printer will operate in 6-Bit Dot Addressable Graphics mode on receiving the Esc-G graphic
command. While in this mode the printer prints one dot line at a time on receipt of 96 graphic
characters or LF command. The LF command advances the paper by one (0.25mm) dot line.
Each horizontal graphic dot is made from 1x6 dot cells; the total number of dot cells per line is
96, corresponding to the 576 total dots per line capacity. Each dot in a dot cell can be turned on
or off by sending specific ASCII characters. For example, 0x3F hex will energize all dots, while
0x40 hex de-energizes all the dots.
