Backspace (BS)
08
This control moves the print position horizontally one character width to the left. If the current print position
is at the left margin, the printer ignores this command.
Horizontal Tab (HT)
09
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 (LF)
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 (VT)
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 (FF)
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 (CR)
