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.
