Use uni-directional printing when precise vertical alignment from line to line is critical. You can also select uni-directional graphics printing in the printer menu (see "Menu Mode" in your printer manual). Incremental Printing Commands (IBM/E/ML) ߜ ML320 Turbo, ML321 Turbo ߜ ML390 Turbo, ML391 Turbo Function Incremental Printing On Incremental Printing Off ASCII ESC i 1 ESC i 0 Dec 27 105 1 27 105 0 Hex 1B 69 01 1B 69 00 The Incremental Printing On command causes the printer to print each individual character as it is received, as opposed to storing information and printing a line at a time. If you have a software application that passes information to the printer one keystroke at a time, this command allows your printer to function as a typewriter. The print location of the next character is indicated by a red "M" to the left of the printhead on the ribbon shield. 82 Chapter 8: Horizontal Control Commands
