• If the value of m is out of the specified range, nL and the following data are processed
as normal data.
• The nL and nH indicate the number of dots of the bitmap in the horizontal direction,
the total number of dots is nL + nH × 256.
• Data of the bitmap excesses the current area will be ignored.
• d indicates the bitmap data. Set a corresponding bit to 1 to print a dot, or to 0 not to
print a dot.
• After complete the transmission of bitmap data, the printer returns to normal data
processing mode.
• If the printing area set by GS L and GS W is smaller than the required printing width
of GS / command, the followings will be immediately executed (the required printing
width of GS / command not exceeds the max. printing width):
①
Printing area extends to the right side, in order to meet the data amount of bitmap
to be printed.
If the step can not provide enough extended width, then the left margin will be
②
①
reduced to meet the data. For each bit of the data in single-density mode (m = 0, 32),
printer prints 2 dots; For each bit of the data in double-density mode (m = 1, 33),
printer prints 1 dot. All the above should be considered when calculate the data
amount could be printed in one line.
