NOTE:
Take a minute to think through the restrictions on the ESC Y and ESC Z
graphics modes. Basically, it just means that you cannot print
a
horizontal line with
fully overlapping dots. Even with the skips, dots on the same row are close enough
together that a line will appear solid. You can, however, print dots in other rows. This
allows you to create much finer curves and diagonal lines in these high-density
modes.
2. Number of Columns
The "start graphics" code is followed by two numbers telling the
printer how many columns to print. For ease of reference, call these
numbers nl and n2.
To find the value of these numbers, determine how many columns
you want to print, then divide it by 256. The value of n2 is the in­
teger portion of the quotient, and the value of n 1 is the remainder
expressed as an integer.
