Vert ical Tab
ASCII Code VT
Hex Code 0B
Dec Code 11
Purpose Prints the data in the buffer and advances the paper to the nex t
vertical tab position.
Comment In Proprinter XL protocol, vertical tab positions are set by control
code ESC B and executed by control code VT. In this mode, if
vertical tabs are loaded, the paper position moves to the next
vertical tab position.
If a vertical tab format is not defined, the paper position is
advanced to the next line at the current line spacing. If a vertical
tab format is defined but no vertical tab positions are set
between the current print position and the end of the form, the
paper position is advanced to the top of the next form. The VT
code resets all single line print attributes. More information on
verticaltabs is provided in Chapter 9, “Vertical PageFormatting.”
