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.
Thiscode is always configured for LF=CR+LF in the P-Series
XQ protocol.
In the P-Series XQ Even Dot Plot mode (high density graphics),
the LF code does not cause paper position motion; the data in
the buffer is plotted and the logical print head is positioned at
character column 1 in anticipation of the Odd Dot Plot control
code to complete high density graphic plotting.
In the P-Series XQ Odd Dot Plot mode (normal density
graphics), the LF code plots the data in the buffer, advances the
paper position a single dot row at the current vertical dot dens ity,
and positions the logical print head at character column 1.
Line Spacing (8or 10.3 lpi)ASCII Code ACK
Hex Code 06
Dec Code 6
Purpose Selects line spacing of 1/8 inch or 7/72 inch for current line only.
Comment The line spacing control code can be placed anywhere in the
data stream before the line terminator code; however, we
recommend that you place the line spacing code at the start or
end of the data line.
After the line is printed at the new line spacing, the default line
spacing is automatically reselected.
