-3 DC3 DD Command (Reading Density Difference Setting Command)
[Explanation]
This command is for setting the density difference allowable from the darkest mark in the CA and EA
modes.
After setting the difference, marks thinner than the setting are cancelled and those in the allowable
range are all output.
The density difference is set at "01" by default. In this case, mark data of the darkest density are
output.
This setting is not stored after the power is turned off.
* This applies to when the CAN command is executed.
