Figure 9 Print Mode Settings
Both double wide and double high can be selected for any of the type faces. When a printed line contains characters
with different heights, the characters are arranged so that bottoms of all characters line up. All characters printed can
be underlined except 90 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)..
4.4.2 Set Bit Image Mode

Table 14 Set Bit Image Mode
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.
In double density mode (+m=01 or 21), for each bit of data received the printer prints one dot horizontally so the
horizontal resolution is 203.2 dpi.
In 8 dot mode (+m=00 or 01), for each data bit received the printer prints three dots vertically so the vertical resolution
is 67.7 dpi.
