Printhead Aging

Print element wear is common in thermal printers. Over the life of a printhead,
wear can result in a change of resistance in the print elements. The change in
element resistance affects the print quality. If needed, the change in resistance
can be compensated for by using the Dark Adjust command. Use the Printhead
Resistance Test in Chapter 5 to warn you when the printhead elements are
beginning to wear out.
