NAME
a2ps - formats an ascii file for printing on a postscript printer
SYNOPSIS
a2ps [ global options ] [ positional options ] [ file1 [ [ positional
options ] ] file2 ... ]
DESCRIPTION
a2ps formats each named file for printing in a postscript printer; if
no file is given, a2ps reads from the standard input. The output is
sent to lpr or to stdout. The format used is nice and compact:
normally two pages on each physical page, borders surrounding pages,
headers with useful information (page number, printing date, file name
or supplied header), line numbering, etc. This is very useful for
making archive listings of programs.
Global options offered by a2ps are the following:
-? Print usage information.
-b Force printing binary files. By default, binary files printing
is stopped before second page (see -nb option).
-c Compact mode for a sequence of files. This option allows the
printing of two files in the same physical page: last page of
the first file in the left (or up) side and first page of the
second file in the right (or down) side. This option is valid
only for twinpage mode (two pages per physical page).
-f Fold lines too large to be printed inside the borders (default
option). Max line size depends on format and font size used and
whether line numbering has been suppressed.
-h Print usage information.
-Ifile
Use the specified file as the postscript prologue for a2ps.
-i Interpret TAB, BS and FF characters (default option). TAB is
replaced by enough spaces to reach next tab stop while BS and FF
have their meanings.
-nb Don't print binary files (default option). To detect such a file
we make use of a very simple heuristic: if the first page of the
file contains at less 75% of non-printing characters, it's a
binary file. First page is always printed.
-nc Don't use compact mode for a sequence of files. The beginning of
each file will be printed in a new physical page.

-nf Truncate lines too large (don't fold).
-nH Don't print page headers.
-ni Don't interpret TAB, BS and FF characters. They will be printed
according to -v option.
-nP Send output to stdout. Default is to send output directly to the
printer
-nr Sheet numbering (see -r option) must be continue for all files
(don't reset on new file). Default option.
-nv Replace non-printing characters by a space.
-n8 Don't print non ascii characters as ISO Latin 1 characters (see
-8 option).
-Pprinter
Send output to the named printer. The default option is send to
the default printer.
-q Print files in quiet mode (no summary).
-r Reset sheet numbering for each new file. Sheet numbering is
used to number physical pages (sheets) as they are printed.
Page numbering numbers the logical pages, of which there are
usually two per physical page (i.e. unless -p or -w is
specified).
-s1 Print output in one-sided mode (only one side of each sheet).
The default option depends on the installation.
-s2 Print output in two-sided mode (front and backside of each
sheet). Default option depends on the installation.
-tnum Set TAB size to num (default 8). This option is ignored if -ni
is specified (see below).
-v Replace non-printing characters so that they are visible and
easy to identify (default option). Control characters (ascii
codes lower than 0x20) are printed like ^X for ctrl-x; the
delete character (hex 0x3f) is printed as ^?. Non ascii
characters (with the high bit set) are printed as M- (for meta)
followed by the character of the low 7 bits. TAB, BS and FF are
handled like non-printing characters if -ni option was taken.
-8 Print non ascii characters (with the high bit set) as ISO Latin
1 characters. By default, these characters are printed as M-
(for meta) followed by the character of the low 7 bits.

Positional options are applied to all files that will be found in the
rest of the command line. The -H option is the only exception: it is
applied only to the next file. Positional options offered by a2ps are
the following:
-1 Print only one page per physical page (single page mode).
-2 Print two pages per physical page (twinpage mode), side by side
or up-down, depending on the printing mode (landscape or
portrait).
-#num To get multiple copies of output, where num is the number of
copies desired of each file named. By default, you get only one
copy.
-d Print the current date and time at the bottom of the page. This
option is affected by the no surrounding border and the no
header options.
-Fnum Changes font size to this value. Default values for font size
are 6.8 in landscape mode, 6.4 in twinpage portrait mode and 9.0
in single page portrait mode. Try other sizes if you think that
these values are too small (or big).
-B Print using bold font.
-Htext
Use this text instead of the file name in the page headers for
printing next (and only next) file. Additional -H directives can
be mixed in with the filenames.
-l Print files in landscape mode (default option). This option may
not be used with the -p option.
-lnum Set the lines per page for printing. The font size is
automatically scaled up to fill in the whole page. This is
useful for printing preformatted documents which have a fixed
number of lines per page. The scaling of the font size will be
suppressed if this option is used with option -fnum. The
minimum number of lines per page is set at 40 and maximum is at
160. If a number less than 40 is supplied, scaling will be
turned off and a warning message is printed on the terminal.
-m Understand UNIX manual output ie: 66 lines per page, no line
numbering and possible bolding and underlining sequences. The
understanding of bolding and underlining is there by default
even if -m is not specified.
-n Output lines are preceded by line numbers, numbered sequentially
from 1.

-nd Don't print the current date and time in the footer (default
option).
-nn Don't number output lines (default option).
-ns Don't print page surrounding borders.
-nB Don't print using bold font.
-nu Don't print filename at bottom of page. Default is to print the
filename, centered, at the bottom of the page.
-nL Don't print user login ID at top of page. Default is to print
the user's login ID in the upper right corner of the page.
(available for Unix systems only)
-p Print files in portrait mode (horizontal pages). The default
option is to use landscape mode.
-s Print page surrounding borders (default option).
USAGE
a2ps generates postcript to its standard output. The user could
redirect this output to a file, pipe it directly to a print command
(like lpr), or to another filter for further processing. By default,
a2ps pipes directly the output to the print command (see -P option).
a2ps -nP file1 > file2
a2ps -nP -p file1 | psnup -n4 | lpr -l -Pps
Don't forget -l option in lpr , if you want that lpr interprets your
postscript program rather than merely printing it as ascii text.
This filter must be used only with text files. Avoid specially output
from TeX, troff or any other such text formatters.
