In 24 dot mode (+m=20 or 21), for each data bit received the printer prints one dot vertically so the vertical resolution is
203.2 dpi.
+n1 and +n2 define the number of dots per line to be printed in the horizontal direction. +
n 1 and + n 2 cannot both have
a value of 0. The range of + n 1 = 0 to 255 dec and the range of + n 2 is 0 to 3 dec so a total number of horizontal dot
position which can be printed with one ESC sequence can vary from 1 to 1023.. If +n1 or +n2 is outside this range, the
ESC sequence is ignored and all data following is treated as normal data.
If the bit image data specified is more than what will fit on a line, the excess data is ignored.
If the width of the printing area set by GS L and GS W is less than the width required by the data sent with the ESC *
command, the margins are re-adjusted to print as much of the graphics data as possible. The right margin is extended
first and then if the data still will not fit then the left margin is readjusted up to the point where the full width of the print
head is used for printing the graphics image.
When 8 dot bit image is selected, each byte of data represents 8 vertical dots to be printed. The MSB is the top dot to
be printed and the LSB is the bottom dot to be printed. For each of the 8 bits within each data byte, a “1” represents a
dot position to be printed and a “0” represents a dot position not to be printed.
When 24 dot bit image is selected, each series of three bytes of data represent 24 vertical dots to be printed. The first
byte represents the top 8 dots to be printed, the second byte represents the 8 dots to be printed in the middle, and the
trird byte represents the bottom 8 dots to be printed. The MSB of each byte is the top dot to be printed and the LSB is
the bottom dot to be printed. For each of the 24 bits within each series of three data bytes, a “1” represents a dot
position to be printed and a “0” represents a dot position not to be printed.
After printing a bit image, the printer returns to normal mode. The graphics mode is not affected by print modes
(emphasized, double-strike, underline, character size, or reverse video) but is affected by the inverted print mode.
