Starts or stops emphasized printing on slip and receipt. In Emphasized
Mode on the slip, each line is printed twice to improve penetration of
multi-part forms and increase print contrast. The second pass is printed
the same direction as the first to ensure accuracy of the overprint.
Printing speed decreases due to the second printing pass.
Exceptions:
Only the lowest bit of n is effective. Emphasized printing cannot be
used with bit-images or downloaded bit-images.
