8–38 IBM Proprinter Emulation
Line Feed
ASCII Code LF
Hex Code 0A
Dec Code 10
Purpose Prints the data in the buffer (if any) and advances the paper one line at
the current line space setting.
Discussion 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 double wide (expanded)
characters if set by the SO command.
Line feed can occur at any place in the datastream and is acted upon
immediately.
