NOTES:
• Since CR is used as the message terminator, you must use ESC [ G or ESC E to
print a CR.
• 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.
