Abstract

Printing method and device enabling a low energy level to be indicated while extending the consumption duration and number of pages printed for a predetermined quantity of energy. According to the invention, detection of a predetermined quantity of energy remaining in an energy source (37) is interpreted by the control means (28) to switch to a printing mode which saves energy so as to indicate to the user an impending lack of energy, while using that which remains sparingly.
