Vertical Tab (VT)
0B
This control causes the vertical presentation 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 presentation 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 presentation position advances to the top margin and the
horizontal presentation position is set to the left margin for subsequent printing.
Carriage Return (CR)
0D
This control moves the current horizontal print position to the left margin. If Carriage
Return equals Carriage Line Feed, a Line Feed is executed when
Carriage Return is received. Otherwise, the vertical position does not change.
Carriage Return is a line ending control code that causes buffered data to print.
Shift Out (SO) / Double-Wide Print
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, Cancel Double-Wide Print, or Set Presentation
Position with vertical movement specified cancels the Shift Out control code.
Shift In (SI) / Condensed Print
0F
This control prints graphic characters in condensed pitch (15, 17.1, or 20 CPI). If
the current print option is 10 CPI this control will condense printing to 17.1 CPI. If
the current print option is 12 CPI this control will condense printing to 20 CPI. If the
current print option is 15 CPI there is no change in density. This control changes
the maximum number of characters that can be printed on one line. Shift In is a
buffer terminating control; if printable data at a different character-per-inch setting is
buffered, that data is printed before the setting is changed. The current presentation
position becomes the next printable column at the new character-per-inch setting.
CPI can be changed within a print line.
