Until vendors ship cloud-aware printers, we need the intermediary cloud print proxy to share our printers with the Cr-48. Unfortunately, cloud print proxy is Windows only. If you're printer is hooked up to a Mac or Linux machine, you're out of luck. But not any longer thanks to the work of Chrome OS expert Jason Michalski. He's created a simple cloud print proxy python script that runs on Linux and Macs and connect your CUPS printers to cloud print. The script prompts you for your Google Account and then discovers your printers automatically.
If you've been waiting to try out cloud print, now's your chance. Let us know how you like it in the comments.
