On the printing dialogue there is an option "alternative printer command", click on it the user could input something onto a text box.
How does anyone use it? I tried to fill "/usr/bin/lpr", "/usr/bin/lpr $1", "/usr/bin/lpr %" all of them does not print, but on my Gentoo Linux if I don't use alternative printer command it prints fine. Could not find the usage on Google.
