Image Data Bytes
The FX-286e printer supports both 8-pin and 9-pin vertical formats.
Since this emulation supports only 8-pin graphics, 9-pin graphics
will not be explained or illustrated here. When 9-pin graphics are
sent to this printer. the byte containing the 9th bit is discarded.
Each image data byte represents a vertical column of eight dots. The
most significant of the eight bits controls the top pin of a column and
the least significant bit controls the bottom pin of that column The
first byte of data (v1) Is the first column (v2) is the second column,
and so on. The illustration below shows byte values of various dot
combinations.
