Select Single Density Graphics Mode
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. Calcu-
lating the parameters, n1 and n2, is described on page 88.

Select Low-Speed Double Density Graphics Mode
If Single Density graphics does not produce high enough density, try this
mode. The number of dots per inch is doubled. However, the speed is re-
duced to half of what it would be with single density. Calculating the pa-
rameters, n1 and n2, is described on page 88.
This is 8-pin single density graphics. The resolution is now 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.

Double Density mode, however, the speed is doubled. Calculating the pa-
rameters, n1 and n2, is described on page 88.

The resolution is still 120 dots per inch. Each 8-inch line can accommo-
date 960 columns of graphic dots. A graphic string that exceeds the length
of the print line is discarded. Take care that adjacent dots in a given dot
row are not printed.
