The man command formats and displays Unix manual pages. It has the ability to format the manual pages and send them to the standard output. From manual pages:
-t Use /usr/bin/groff -Tps -mandoc -c to format the manual page, passing the output to stdout. The output from /usr/bin/groff -Tps -mandoc -c may need to be passed through some filter or another before being printed.
So simply type…
man -t man_page_name > man_page_name.ps
… and it will create a postscript formatted file containing the man page. You could then convert it to PDF or whatever you want.
