Line Feed, with Carriage Return LF 10 0A
This command makes the printer print a line, then moves the print position down one line and
executes a carriage return, putting the print position at the left margin. The amount of vertical
movement depends on the current line spacing. (See “Line Spacing,” below for details.)
In the IBM and Epson emulations, this command cancels one-line double width printing.

Graphics Line Feed, without Carriage Return ESC DC2 27 18 1B 12

it possible to overstrike a line of printing or create special effects such as double underlines.
