12. COMMAND DESCRIPTION
12.1 Horizontal Control
1) Carriage return—execute
(a) Code: CR
(b) Compatibility: EPS FX/IBM III/ML
(c) Function:
Initiate printing action; print data in the print buffer by causing a print block change
and set the next printable data’s print position to the left margin.
(d) Additional details:
• If Auto-LF is activated, a CR will also cause a LF to execute. This action will take
place if there is, or if there is not data in the print buffer.
• The text feature, “Double Wide (expanded)—one line only”, designated by SO and
ESC SO (Epson mode only) will be reset since the “CR” terminates the current
print line.
2) Backspace
(a) Code: BS
(b) Compatibility: EPS FX/IBM lll
(c) Function:
Print the data in the print buffer and move the printhead one current character width
to the left.
(d) Additional details:
• Size (distance) of the BS are as follows:
BS + DBL-Width → double width BS
BS + char. pitch → BS the amount of the current char. pitch
BS + Inter-char clearance → BS normal char width + clearance
BS + Proportional → causes the print head to backspace a 10 CPI character width.
• If a multipass character (ex. double height characters) is in the print buffer, when
BS is executed, the paper is reverse feed back to the original printing position of
the multipass character, and the character is printed. (Precise printing is not
guaranteed).
• Once the current print position has reached the left margin, BS will be ignored.
(Epson)
• The print head backspaces to the left margin position. (IBM)
• BS + right, center, full justification → BS is ignored.
3) Backspace
(a) Code: BS
(b) Compatibility: ML
(c) Function:
Move the printhead one current matrix cell width (character cell and Inter-character
clearance columns) to the left.
