GENERAL DESCRIPTION
1.8.3 BIT-IMAGE PRINTING
This printer offers the
following four standard print densities (“dpi” indicates “dots per inch”):
120 dpi (including half dots): Triple speed
180 dpi (including half dots): Double speed
240 dpi (including half dots): 1.5 speed
360 dpi (including half dots): Normal speed
The firmware implements the print densities as shown in Table 1-16.

NOTES: 1. Dot density is in dots per inch; print speed is in inches per second.
2. The format of the graphics command is ESC* m n1 n2 [DATA]. Column 2 of the table shows
the significance of the various options for m.
The firmware handles the print densities as shown in Table 1-17.
