You'll still need to have that Windows PC acting as an intermediary, but folks looking to use Google's Cloud Print service now at least have considerably more devices at their disposal to print documents from. Following up its roll-out to Chrome OS netbooks last month, Google has now announced that it's begun rolling the service out to its mobile Google Docs and Gmail sites, which you'll be able to use to print documents from most mobile devices that supports HTML5 -- those running Android 2.1+ or iOS 3+, for instance. What's more, while you will still need that Windows PC connected to your printer for the time being, Google now notes that both Mac and Linux support are "coming soon."
