Line Feed
ASCII Code LF
Hex Code 0A
Dec Code 10
Purpose Prints the data in the buffer (if any) and advances the verti cal
character position one line at the current line space setting.
Comment If configured for LF equals new line (LF=CR+LF), the logical
print head is positioned at character column 1 of the new line.
Otherwise, the logical print head does not move when
configured for LF function only (LF=LF ONLY). The LF function
cancels all single line print attributes such as double high
(elongated) and double wide (expanded) characters.
Line Feed n /216Inch (One Line Only)
ASCII Code ESC J n
Hex Code 1B 4A n
Dec Code 27 74 n
Purpose Advances the vertical character position n /216 inch for one line
only.
where:
n =1 through 255 (hex 01 through hex FF)
Comment The
n /216-inch line feed control code is effective for one line
only. All single-line-only print attributes are canceled.
If the emulation is configured for LF equals newline
(LF=CR+LF), the paper advances one line at the current line
space setting and the logical print head is positioned at
character column 1.
Thep aper position moves only in multiples of the current dot row
spacing. If the distance to move is other than a multiple of the
current dot row spacing, the remainder is added to the next
paper motion command.
Small values of
n may result in overlapping lines. Overlapping
lines may also occur if print attributes such as Elongated
(Double High), Superscript, or Subscript characters are used on
the same line. Printing at different horizontal and vertical
densities do not overlap.
Example The following example illustrates
n /216-inch line spacing.
