This command retrieves the part number of the ribbon
cartridge installed in the printer. There is a 12 character max
for the size of string returned since the cartridge allows for 10
character part numbers.
If a ribbon cartridge is not installed, or
if the ribbon cartridge option is not present, then the command
returns an empty string.
