Density varieties
Although all the examples so far in this section have been in the single-
density graphics mode, there are seven other eight-pin densities and two
that use all nine pins.
Nine-pin graphics is not necessary for most uses, but you can find the
command (ESC ^) in the Command Summary in Chapter 8. The four
most common eight-pin modes are ESC K. ESC L, ESC Y, and ESC Z.
There is also a general purpose command for any of the eight-pin
graphics modes: ESC l . This command is used in the same way as the
individual commands. except that before n1 and n2 you must send the
code for the graphics mode required.
The different graphics modes are summarized in the following table:
