Direct the output to a file or to a printer. Here are a couple of examples: $ groff -Tps -man /tmp/chown.1 > /tmp/chown.ps $ groff -Tlj4 -man -l /tmp/chown.1 The first example creates PostScript output (-Tps) and directs it to a file called /tmp/chown.ps. That file can be read by a PostScript previewer (such as Ghostscript) or sent to a printer (lpr /tmp/chown.ps). The next example creates HP LaserJet output (-Tlj4) and directs it to the default printer (-l option).
