LDARKNESS

Syntax

ldarkness n | {expr}

Description

Setting this value will cause UnForm to send a thermal printer darkness command (~SD in Zebra) to the printer.  The darkness parameter can be a number n or a numeric expression expr.  The value of n should be an integer between 0 and 30, based upon current ZPL documentation.

Alternatively, in a prepage or  prejob code block, the variables ldarkness$ or zdarkness$ can be set to a numeric string (i.e. ldarkness$=str(5)).
