If you're asking about how to print from the command line the command you're looking for is usually lpr or lp. These are frontend tools for printing files from the command line.
NOTE: You can search the man pages using -k to search for keywords. If you'd done man -k print you would've found these pages.
To see what printers are available you can use lpstat -a, for example:
$ lpstat -abrfax accepting requests since Wed 19 Jun 2013 06:20:02 PM EDTBrother-MFC-4800 accepting requests since Wed 05 Jun 2013 01:35:48 PM EDTBrother-MFC-J825DW accepting requests since Mon 17 Dec 2012 01:54:12 PM ESTmfc-8480dn accepting requests since Wed 19 Jun 2013 06:19:59 PM EDTs820 accepting requests since Wed 19 Jun 2013 06:20:01 PM EDTs820-scully accepting requests since Wed 19 Jun 2013 06:20:02 PM EDTStylus-NX300 accepting requests since Fri 08 Mar 2013 03:13:58 PM ESTTo print to one of these printers I generally use the lp command like so:
