For example, if you choose to print a bar code with the Code
39 symbology, your printer prints out a label similar to this
one:
*0123456789*
You can use two different printhead loading modes with the
7421 printer: Mirror Printing mode or Inverse Printing mode.
If you select Mirror Printing mode, the printer reverses the order
of the data that is loaded into the printhead.
If you select Inverse Printing mode, the printer inverts all pixels
in an image before it sends the data to the printhead. Only use
Inverse Printing mode to print a small area of a label.
Note: Intermec does not recommend using Inverse Printing mode for
printing multiple labels. The printhead is not covered under warranty
if you use Inverse Printing mode for printing multiple labels.
