MESSAGE FORMATTING
•The cursor row position is not affected by the currently selected font. The display always has 4 rows, so when writing with the large font, actually two rows are written to: the current one and the one below it. You will need two ESC E commands to step from one row to the next when using the large font.
•The cursor column position is affected by the currently selected font. Therefore, column 6 is 36 pixels from the left border only if you last selected the 6x8 font; otherwise it could be 48 or 72 pixels from the left border.
