Google Cloud Print is now available now in the latest dev channel build 9.0.597.10 of Chrome for Windows.
"After installing, you'll be able to enable Cloud Print from Options --> Under the hood --> Google Cloud Print. Log in to your Google account and Google will connect your local printers with Cloud Print, so that you can print documents from other devices."
"Google Cloud Print is built on the idea that printing can be more intuitive, accessible, and useful. Using Google Cloud Print you can make your printers available to you from any Google Cloud Print enabled web or mobile app," explains Google.
Since none of your printers is Cloud Print-enabled, you'll have to use a software that connects Cloud Print with your printers. Google Chrome 9 for Windows includes a Cloud Print Connector and you'll only be able to use Cloud Print while the connector is running.
