3 – 39Your printer is designed to maximise speed by printing alternately from the left andright (bidirectional printing), rather than moving the printhead back to the left marginso that each line prints from left to right (unidirectional printing).Use unidirectional printing when precise vertical alignment from line to line is critical.You can also select unidirectional printing in Menu Select Mode.Unidirectional printing Decimal Hex ASCII CompUnidirectional printing 27 85 n 1B 55 n ESC U n E P An = 1: Begin unidirectional printing n = 0: Begin bidirectional printingOne line unidirect. printing Decimal Hex ASCII CompOne line unidirect. printing 27 60 1B 3C ESC < EEpsonThis command activates unidirectional printing for one line only.EpsonUse this command to control the speed of printing.
