You can also control this feature through the printer menu (see "Menu Mode"in your printer manual).Reverse Line Feed Commands (IBM/E/ML) ML320 E/I, ML321 E/I ML320 Turbo, ML321 Turbo ML520, ML521 ML320 Std., ML321 Std.

Be carefulwhen using reverse line feeds with the optional pull tractor: print registration may be affected.In the Epson emulation, the reverse line feed command causes the printer to finish printing theline, then move the print position up an amount equal to n/216": n can be any whole numberfrom 0 to 255. If you use n = 0, the command will be ignored. No carriage return is executed,regardless of the setting for Auto CR in the menu (see “Menu Mode” in your printer manual).
