HP L 5 manual Monochrome Printing, Monochrome Print Mode Command, ?&b#M

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
# = 0	-	Print in mixed render algorithm mode
1	-	Print using gray-scale equivalent
Default	=	0
Range	=	0, 1 (command is ignored for invalid values)

This command must be sent prior to printable data, or it is ignored. The command must be sent at the start of a job, since few, if any, applications support a mixture of color and monochrome printing of color images within the same document.
