This control moves the print position to the next horizontal tab stop. If there are no
tab stops to the right, or if the next tab stop is beyond the current right margin, the
control is ignored.
Line Feed (ESC LF)
1B 0A
This control advances the paper one line. The horizontal position does not change
unless automatic carriage return mode is activated from the operator panel
Configuration menu. If the paper advance crosses the bottom margin, the printer
completes all deferred printing on the current page and then does an automatic
form feed.
If skip perforation mode is active and the bottom margin is crossed, the vertical
position on the new page following the automatic form feed will be the top-of-form
position. If skip perforation is not active, the vertical position on the new page is the
point immediately following the previous print line.
Vertical Tab (ESC VT)
1B 0B
This control causes the vertical print position to be advanced to the next vertical tab
stop. The horizontal position is not affected unless automatic carriage return mode
is activated from the operator panel Configuration menu. If there are no tab stops
past the current vertical print position, Vertical Tab is treated as a Line Feed.
Form Feed (ESC FF)
1B 0C
This control causes a new page to be started. Form Feed is a line end and page
end control; it causes all deferred printing that may have been buffered for the
current page to be completed and the form physically advanced to eject the current
page. The vertical print position advances to the top margin and the horizontal print
position is set to the left margin for subsequent printing.
Carriage Return (ESC CR)
1B 0D
This control moves the current horizontal print position to the left margin. The
vertical print position does not change unless automatic line feed mode is active
(see “Set Auto Line Feed (ESC 5)” on page 197).
Shift Out (ESC SO) / Double-Wide Print
1B 0E
This control causes the printer to start double-width printing. Double-width printing
prints the characters twice as wide as the current character spacing. This results in
half as many characters per inch. Each character takes up the space of two
single-width characters. A Carriage Return, Line Feed, Form Feed, Vertical Tab,
