Single-Density Graphics
Enters one line of 8-dot single-density graphics into the print buffer. Any print command is
required to print the line, after which the printer returns to normal processing mode. When
the print buffer is full, incoming data will be accepted but not printed. Single-density mode
allows 0-224 dot columns. The number of bytes sent is represented by the formulas in the
second table. Each bit corresponds to two horizontal dots. Compare to Set Bit Image Mode
on page 79.

Double-Density Graphics
Enters one line of 8-dot double-density graphics into the print buffer. Any print command
is required to print the line, after which the printer returns to normal processing mode.
When the print buffer is full, incoming data will be accepted but not printed. Double-
density mode allows 0-448 dot columns. The number of bytes sent is represented by the
formulas in the second table. Each bit corresponds to one horizontal dot. Compare to Set
Bit Image Mode on page 79.
