NAME

prfl − IBM 4201 Proprinter/IBM 5152 Graphics Printer nroff post-processing filter

SYNOPSIS

prfl [ −g ]

DESCRIPTION

Prfl is a post-processing filter to convert the intermediate output of nroff(1) and colpro(1) to the IBM 4201 Proprinter control sequences and characters.  In particular, the filter does the following:

 
1.  Converts strings of the form _<bs><char>_<bs><char> to <start underlining>
    <char><char><stop underlining>.
 2.  Converts sequences of the form <Esc>Ax to IBM 4201 Proprinter nonprinting control commands.
 3.  Convert sequences of the form <Esc>[B,C]? to a set of sequences to download special
    characters. If the -g option is specified, these characters are printed in graphics mode.
 4.  Convert sequences of the form <Esc>Dx to x+130 (nroff cannot send codes over 127).
 5.  Convert sequences of the form <Esc>Ex to print the code x using the all-characters font.
 6.  Convert sequences of the form <Esc>Fx to print the code x+130 using the all-characters font.
 7.  Convert <Esc>9 to <1/2 space linefeed>.

The −g option uses only those escape sequences understood by the IBM 5152 Graphics Printer. 

Prfl is provided primarily for use by proff(1).
