n Higher resolution graphics
There are seven graphics modes you can use; they are
summarized in Table 7-2.
Table 7-2
Dot graphics commands
You will notice that the higher the density of the graphic
mode, the more points you will need to plot. Higher density
modes also take longer to print. The double density double
speed mode ignores every second column of dots to give you
a quick printout for debugging purposes; you can then change
to true double density graphics for the final printout.
If your software cannot access the < ESC > “*” command,
there are individual letter escape commands for four of the
modes. See Table 7-3.
