Compuprint 4247-Z03 Programmer Manual - Manual (Page 30)

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 13).
Shift Out (ESC SO) / Doube-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, Double-Wide Continuous Mode, or Cancel Double-Wide Print with vertical movement
specified cancels the Shift Out control code.
Shift In (ESC SI) / Condensed Print
1B 0F
This control prints graphic characters in condensed pitch (15 CPI, 16.7 CPI, 17.1 CPI or 20 CPI).
