Graphics Character Set; Special Graphics Characters - Epson LX-86TM User Manual

Graphics character set

The Lx-86 printer's Read Only Memory (ROM) also contains the
32 graphics characters that you see in Figure 6-6.
Undoubtedly you can think of uses for many of the shapes and
symbols available in this set, and you can combine the line graphics
characters (the ones on the first row) to form various sizes and shapes
of boxes and other figures that use straight lines.
To print these graphics characters you must use either a program-
ming language or a computer with a graphics shift or other special key
that allows you to send graphics codes.
Sending the codes for these characters to the printer is a two-step
process just as it is for the international characters. In BASIC, first
you send CHR$(27) "m"CHR$(4) to turn on the graphics character
set, then you send the code numbers given in Figure 6-6. After you
have used the ESCape code to turn on the graphics character set, the
LX-86 prints the codes from 128 through 159 as graphics characters.
You can change pitch and weight with the graphics characters
just as you can with the other characters in the ROM of the LX-86.
The characters in Figure 6-6 are printed in double-width elite.
The printout below shows the characters in pica:
