• 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.
