Chapter 6
Dot Graphics
The SQ-2000 has all the dot graphics capabilities of the other
Epson printers as well as the ability to produce dot graphics
using all 24 of the nozzles in the print head. This gives the
SQ-2000 approximately three times the vertical resolution of the
other printers.
This chapter covers how the SQ-2000 produces dot graphics,
explains the commands used to produce the 10 different graphics
densities, and briefly describes several applications of dot
graphics.
If dot graphics is a new subject to you, you may want to study
the chapters on dot graphics in the User’s Manual for either the
Epson FX or RX series printers. These manuals, which are avail-
able at your Epson dealer, provide detailed tutorials on some of
the simpler applications of dot graphics. Because of the upward
compatibility between the Epson printers, the example programs
presented in those manuals will work equally well on the
SQ-2000 printer.
How the SQ-2000 Prints Dot Graphics
In the last chapter you learned how to address the individual
nozzles in the SQ-2000’s print head to create your own charac-
ters. Now you will learn how to address the individual nozzles in
the print head to print any graphics you
want.
The method of addressing the nozzles in the print head for
graphics is very similar to the method used for creating user-
defined characters. In fact, when you are using the 8-nozzle (also
called 8-dot) graphics options, the method of nozzle addressing is
much simpler.
