Command 
Character
The format command prefix is a two-digit hex value used as a parameter place marker 
in ZPL/ZPL II format instructions. The printer looks for this hex character to indicate 
the start of a ZPL/ZPL II format instruction.
Set the format command character to match what is used in your label formats.
Important • You cannot use the same hex value for the format command prefix, 
control character, and delimiter characters. The printer must see different 
characters to work properly. If you are setting the value through the control 
panel, the printer will skip any value that is already in use.
