Option 31 (Calculate Check Digit)
The printer generates a check digit if you apply Option 31 to the
field. You cannot use this option if the field contains a UPC, EAN,
or Code 39 (with the MOD43 check digit) bar code.
Syntax

Example
R,31,G,5 p
Generates a check digit using the previously defined check digit
scheme 5.
Option 50 (Bar Code Density)
You can apply this option to bar code fields when you want to
create custom densities. When you apply this option, it overrides
the density value in the bar code field.
When using this option, set the density parameter in your bar
code field to the default value. You can only use this option once
for each bar code field. This option overrides the density
selected in the bar code field.
Bar codes produced using Option 50 may not be scannable. The
additional character gap, narrow space, and wide space
parameters are valid
only
with Code 39 and Codabar. If these
parameters are specified for any other bar codes, they will be
ignored by the printer.
Do not use Option 50 with UPC or EAN
bar codes.
