Line Feed LF 0A
The Line Feed (LF) Control Code advances the paper one line in Character Mode or one dot-row
in Plot Mode.
If the Auto Carriage Return Parameter is set to ON, the printer also moves the print position to
the left margin when it receives a Line Feed Command.
If Print on Paper Command (POPC) is enabled, any character data previously received is printed
before the move.
Character Mode
When a LF Command is issued in Character Mode, the actual distance the paper moves
in response to a single LF Command depends on the LPI or the Variable Line Spacing
setting.
Plot Mode
When a LF Command is issued in Plot Mode, the actual distance the paper moves
depends on the plot density setting for vertical DPI. For example, with a density of 100
dots per inch the paper would advance 1/100", and with a density of 50 dots per inch the
paper would advance 1/50”.
Save Print Position
The Save Print Position (SPP) Command saves the current print position into the printer’s
memory. The SPP escape sequence is:
ESC P B
1B 50 42
Restore Vertical Print Position
The Restore Vertical Print Position Command moves the paper to the last saved vertical cursor
position. If no vertical cursor position has been saved on the current form, the paper moves to
the current top-of-form. In either case, the active print position is moved to the left margin. The
escape sequence is:
ESC P A
1B 50 41
