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 rst to ensure accuracy of the overprint. Printing
speed decreases due to the second printing pass.
Exceptions
Only the lowest bit of n is eective.
Emphasized printing cannot be used with bit-images or downloaded bit-images.

improve penetration of multi-part forms and increase print contract. The second pass is printed the same direction as
the rst to ensure accuracy of the overprint. The printer is reset to the standard print mode after a clear printer (0×10)
command is received.
