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 available 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.
