[Notes] • n specifies the bitmap number of RAM gray scale bitmap.
• yL and yH specify the number of dots in the horizontal direction for the Flash bitmap
( yL + yH × 256) × 8.
• zL, zH specify the number of dots in the vertical direction for the Flash bitmap ( zL +
zH × 256) × 8.
• This command is disabled in upside-down mode.
• If the related parameter of this command exceeds the defined range, this command
is disabled.
• If the RAM gray scale bitmap defined by this command exceeds the maximum
download capacity of RAM 128kB, this command is disabled.
• The downloaded RAM gray scale bitmap is erased when the printer is turned off.
• Format of the gray scale bitmap: every dot line of gray scale image is indicated by
four dot lines of data. The four dot lines of data form different levels of the gray scale
bitmaps. The table below shows the gray scale level of a dot and the data of the dot
in the four dot lines of data. The corresponding relation is as below:
