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 B.?). 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 ['system' and printing in Windows - Ruby - Ruby-Forum](http://www.ruby-forum.com/topic/83266) for some hints.
