characters are arranged so that bottoms of all characters line up. All
characters

degree-rotated
characters. The space caused by the tab command HT is not underlined.
The thickness of the underline is defined by ESC – regardless of the
character size. Default = 0hex (12 x 24 matrix)..

If +m is not one of the specified values, the rest of the ESC sequence is
ignored and all information starting with +n1 is treated as normal data.
In single density mode (+m=00 or 20), for each bit of data received the
printer prints two dots horizontally so the horizontal resolution is 101.6
dpi.
