It depends on your OS for one thing. I'm not aware of a project that
provides a uniform cross-platform API to printing for ruby (that
doesn't mean there isn't one). The closest thing I know of is
Gtk::PrintOperation from ruby-gtk [ http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3APrin...
].

HTH,

I'm not sure. I assume you could use the win32ole module that ships
with ruby 1.8 [1], or perhaps one of the third-party win32 modules
[2]. But I have no idea how. Maybe someone who knows about ruby +
win32 can help (Daniel Berger?). You could also probably write a
little C extension to call the windows API, but that may be more work
than necessary. Sorry I can't be of more help.

You can open file 'PRN:' (note the double colon). That should provide
you with a line printer
(i.e. no graphics, just ascii output). I'm not sure whether it is
still supported.

Other than that, I guess the easiest way would be to create pdf
somehow and print that,
either using some command line tool, or Win32API/Win32OLE.

See http://www.ruby-...topic/83266 for some hints.
