• 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
f
ont. The display always has 6 rows, so when writing with the large
font, actually three rows are written. You will need
two ESC E com-
mands to step from one row to the n
ext when using the large font.
• The cursor column position is affected by the currently selected
font. Th
erefore,
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.
