USER-DESIGNED DOT GRAPHICS
Designing and printing graphics is similar to the procedures
for characters, except that the printed width can range from one
to 1920 dots. Selection of the appropriate line spacing will allow
rows of dots to link seamlessly, and in this way you may design
and print a whole page of data. In the dot graphics mode, you
directly address all dot positions on the page if desired. The
graphics mode can print as many as 240 dots per inch compared
with the standard resolution of 60 dots per inch (dpi).
The command to print normal density (60 dpi horizontally, 72
dpi vertically) uses this format:
(ESC) “*” CHR$(O) nl n2 ml m2 . . . . .
