Chapter 8: Horizontal Control Commands

This chapter describes the commands for horizontal control including the following:
Backspace/Carriage Return Commands

Margin Setting Commands

Horizontal Tab Commands
Indent Commands
Backspace & Carriage Return Commands (IBM/E/ML)
ML320 E/I, ML321 E/I
ML320 Std., ML321 Std.
Function
Backspace
Carriage Return
The backspace command moves the printhead one character to the left. The actual width of the
backspace depends on the current pitch. If you're using proportional spacing, the BS command
moves the printhead 1/10" to the left.
The carriage return command causes the printer to print data from the print buffer and return
the printing position to the beginning of the line. If the printer menu item Auto LF (under Set-
Up group) has been set to YES (factory default is NO), the printer automatically adds a line feed
to each carriage return.
Margin Setting Commands
Set Left & Right Margins Command (IBM)
ML320 E/I, ML321 E/I
Function
Set Left & Right Margins ESC X n m
In the IBM emulation, the margins set by the Left & Right Margin command are set by character
columns. The actual position of the margin depends on the current pitch: a margin of 10
columns will come out as 1" in 10 cpi and 1/2" in 20 cpi. If the current pitch is proportional,
the margin is set as though it were 10 cpi. However, once you've set a margin, its absolute
position remains the same, even if you change the pitch, until you specifically reset the margin.
This saves you the work of adjusting margins with every pitch change in your document.
Note: You should always send margin commands at the beginning of a line.
Parameter n
Parameter n sets the left margin and can be any value from 0 to 254. Use a value of 0 if you
want to change the right margin only. The default setting for the left margin in the IBM
emulation is 1.
