With this 8-pin graphics mode, the number of dots per inch has gone up to 4x what it
was in single density.
The resolution is now 240 dots per inch. Each 8-inch line can accommodate 1920
columns of graphic dots. A graphic string that exceeds the length of the print line is
discarded. Make sure adjacent dots in a given dot row are not printed.
To calculate n1 and n2, divide n (total number of dots needed for the graphics string) by
256. Then n2 is the quotient (the whole number) and n1 is the remainder. If you require
less than 256 dots (columns), then n1 indicates the number of dots and n2 is set to zero.

These 9-pin graphics control codes also require two parameters,
They are calculated differently than in the 8-pin graphics modes.
First, determine the value for
graphics string. Divide
quotient (the whole number) and
dots (columns), then
n1
Enables single density 9-pin graphics mode. The resolution is 60 dots per inch. Each 8-
inch line can accommodate 480 columns of graphic dots. A graphic string that exceeds
the length of the print line is discarded.
To calculate the values for n1 and n2, determine the value for n, which is the total
number of dots needed for the graphics string. Divide n by 2, then divide the result by
256. Then n2 is the quotient (the whole number) and n1 is the remainder. If you require
less than 256 dots (columns), then n1 indicates the number of dots and n2 is set to zero.

Enables double density, 9-pin graphics mode. The resolution is 120 dots per inch. Each
8-inch line can accommodate 960 columns of graphic dots. A graphic string that
exceeds the length of the print line is discarded.
To calculate the values for n1 and n2, determine the value for n, which is the total
number of dots needed for the graphics string. Divide n by 2, then divide the result by

less than 256 dots (columns), then n1 indicates the number of dots and n2 is set to zero.
