I want to get man pages to stout. However, I have not managed a way to do that.
Pseudo-code about what I am trying to achieve
man man | lpr
How can you print a manual, such that you see first how many pages is going to be printed?

man -Tps man | lpr
This tells man to format the output as a postscript file which can be piped directly to a printer. See the man page for further -T (troff) formatting options.
To preview the output pipe it to a file and view it with gv or okular.
man -Tps man > manual.ps
gv manual.ps

Do you know how you can get the number of pages before you print the manual? – Léo Léopold Hertz 준영 Jun 02 '09 at 21:15

See my edits above, I can't think of a way to count the pages from the command line. – Sekenre Jun 02 '09 at 21:26

It seems that OS/X's man does not have the option T. – Léo Léopold Hertz 준영 Jun 26 '09 at 14:34

@Masi: Try using man -t python | lpr Your version has that option. – Sekenre Jun 27 '09 at 19:51

@sekenre: Thank you very much! --- The command works by the use of Python. – Léo Léopold Hertz 준영 Jul 03 '09 at 16:02

man ls | col -b | lpr -P my_printer
This prints the man page for "ls" formats it using "col" and then prints on the printer named "my_printer"
The formatting isn't required, but gets rid of special characters making it easier to read.

Newer versions of man (at least my version on openSuSE 11 :) ) automatically detect if output is a terminal or a pipe. If you want non-formatted man pages to stdout, try:
man man | cat
For manpages going to the printer, I like:
man man | a2ps --stdin='man(1)'

Answer to # of pages question above(need 50 rep to add comments):
man ls | wc -l | awk '{ print $1/60 }'
The default # of lines per page is 60, so if you aren't changing that, then just divide by 60 and round up. I forget how to make awk treat FP as INT so that it rounds for you.

sorry for the late response. FP = floating point; INT = integer. It would be useful to have it translated into an INT if you were planning on using the output for another automated purpose(ie - piping a one liner or in a script). – Josh Jul 02 '09 at 05:33
