Google Cloud Print just launched, and we're glad to announce... it works! At least from the Chrome test page.
Google are expected to launch cloud print-enabled Android apps later today, which will mean you can print from your phone direct to your printer -- or indeed any printer that's connected to Google Cloud Print.
The gallery should walk you through each of the steps.
I want to send a print job to a remote printer in an office in another city. I can achieve this using Google Cloud Print. However, every time I print I have to select my printer from the Google Cloud Print dialogue box.
