Printronix P9000 Series manual Carriage Return, Define CR Code CR=CR+LF

Carriage Return

	ASCII	Hex	Decimal
P-Series/
Serial	CR	0D	13
Purpose	Returns the logical print head to the first character column (resets the pointer
	to the first character position).
Comment	The CR code may or may not cause printing or paper motion, depending on
	the DEFINE CR CODE configuration parameter value. If the DEFINE CR
	CODE submenu displays:

DEFINE CR CODE

CR=CR

the characters following the CR are printed over the previous characters on the line. If identical characters are placed in the same position on the line, those characters will be printed in bold (double strike) print when the OverF strike Mode is enabled from the control panel.

The CR=CR configuration causes subsequent printable data to overprint previous data at half speed if Overstrike is enabled from the control panel (and prints somewhat faster if Overstrike is disabled), unless an intervening paper motion command is received. See the Overstrike/Overlay section on Page 6-1.

If the DEFINE CR CODE submenu displays:

DEFINE CR CODE

CR=CR+LF

control code CR is converted to perform a carriage return and line feed funcF tion.

The CR code in Serial Matrix printer protocol cancels expanded (double wide) print when set by code SO and ESC SO (single line printing attribute).
