In high speed printers associated with text or word processing operations, bidirectional printing is an important expedient by which printer speeds are increased. In the systems which control such high speed bidirectional printers, all formatting including calculation of particular tab escapements is carried out in the forward direction. Consequently, when the printer is to be operated in the reverse mode, it has been customary to recalculate the tab escapement which already has been calculated in the forward mode.
