This command determines what the ESC/P
®
emulation does with ASCII characters 10
and 13. These are the ‘line feed’ (LF) and ‘carriage return’ (CR) characters. The
“LF” causes the printer to move down to the next print line, and the “CR” causes the
printer to move back to the left margin position. In most cases, these are sent at the
ends of lines to position the printer for the next line of text.
Some host computers send one or the other of these, and some send both, each hoping
to move to the left margin and down to the next line. You can determine the effect
of these characters when they are received. If your host sends only a CR or LF to
complete each line, you should set this to LF=CR+LF CR=CR+LF so that both a
carriage return (return to left margin) and line feed are executed when just one of
these control codes is received by the printer.
