Monochrome Printing
The Monochrome Print Mode command converts each color value to
its grayscale equivalent. This improves throughput, costs less to print,
and eliminates waste by providing a draft mode.
Monochrome Print Mode Command
The Monochrome Print Mode command designates whether to print
using the current rendering mode or a fast gray-scale equivalent.
Pages printed using the gray-scale equivalent do not use any color
and therefore print faster and more economically.
?&b#M
This command must be sent prior to printable data; otherwise, the
current page is closed and printed. It may be sent on a page-by-page
basis.
# = 0 - Print in mixed render algorithm mode
1 - Print using gray-scale equivalent
Default =0
