This is a simple method of printing graphics. 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 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.

If Single Density graphics does not produce high enough density, try this mode. The
number of dots per inch is doubled to 120 dots per inch. Each 8-inch line can
accommodate 960 columns of graphic dots. However, the speed is reduced to half of
what it would be with single density. A graphic string that exceeds the length of the print
line is discarded.
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.

This 8-pin graphics mode produces the same density as the Low-Speed Double Density
mode at double the speed.
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. 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.
