This is a fork of Torisugari's code, which adds a -noheadfoot
option. See his documentation of an older
version.
When this extension is installed in your Firefox you can use it like this:
firefox -print http://www.example.com/index.html
firefox -print http://www.example.com/index.html -printmode PNG
firefox -print http://www.example.com/index.html -printdelay 10
firefox -print http://www.example.com/index.html -printmode pdf -printfile ../foo.pdf
firefox -print http://www.example.com/index.html -printmode pdf -printfile ../foo.pdf -noheadfoot
The new -noheadfoot options suppresses the header and footer that
would otherwise be added to the printed page.
