An electronic font used in a resistive ribbon printer has the magnitude of its print current determined by the percentage of print elements (pels) that have to be activated to print the character, with alternate characters being used under certain constraints when over 50% of the pels would have to be turned on. This energy mamagement prevents damage to the printer. Four-bit binary codes are employed for determining the print current to be utilized for printing each character of an electronic font used in a resistive ribbon printer. No change of the normal print current is made for codes representing when 10-32% of the pels are turned on to print a character.
