Note:
For detailed information on programming for EPSON’s Stylus COLOR and other
high-resolution color printers, see “Extended ESC/P 2 Programming Guide” at
the end of this chapter.
To eliminate potential command conflicts during raster graphics printing,
EPSON provides a special graphics mode. In this mode, some commands are not
available. See “Graphics mode” for details.
Bit-image graphics
ESC/P 2 ESC/P 9-Pin ESC/P
Bit-image graphics is available on all printers. Data handling varies, however,
depending on the number of pins in the print head.
The steps for printing bit-image graphics are as follows:
1. Determine vertical and horizontal dot density.
2. Prepare and organize bit-image data.
3. If you plan to send more than one line of graphics, set the line spacing to
match the height of the print head.
4. Set the vertical and horizontal print position to the top left corner of the
graphics line.
5. Send one line of bit-image data to the computer.
6. Complete the line with a CR and LF command.
7. Repeat steps 5 and 6 until the full graphics design is printed.
Determining vertical and horizontal dot density
ESC/P 2 ESC/P 9-Pin ESC/P
The ESC * command is used to print bit-image graphics.
The format of this command is as follows:
ESC * m nL nH d1 d2 . . . dk
m Specifies the dot density and printing speed. The dot
density can be specified from 60 × 60 dpi (dots per
inch) to up to 360 × 360 dpi, depending on the
number of pins in the print head. The printing speed
depends on the printing of adjacent horizontal dots;
by not allowing the printing of adjacent dots, you
increase the printing speed.
