I was just thinking about doing something really quick like rendering a page that is printer friendly using Rails and just having them hit CTRL+P but if you wanted to bypass that and send it straight to the printer that works too. From a quick Google search it seems the best way is to issue OS commands using Ruby and sending it a generated PDF file. Here is a Stackoverflow link about it but I'm sure more searches will reveal better information, http://stackoverflow.com/questions/1608593/printing-a-file-to-a-printer-in-ruby. The only reason I would do it the other way is just to allow the user to preview the file before it is sent to the printer but if everything works and you don't mind reprinting or whatever then sending it straight to the printer would be faster for the user.
Hope that helps.
