When Google launch their Chrome OS (hopefully later this year) they will be bringing a relatively new concept (cloud computing) to the mainstream, apparently one big challenge for Google has been creating a print system for local printers.
As the operating system will be entirely web-based you will not be able to simply put in your driver CD and install your printer, instead Google need to develop a reliable system which will allow you to print to locally connected and shared printers.
Apparently to do this Google will in affect have to act as a print server, therefore when printing a document you will send data to their Cloud Print system, which will then send print jobs to the correct printer.
Their Cloud Print system is still under development, and I would have thought it would be under development for a while as their target is to “build a printing experience that enables any app (Web, desktop, or mobile) on any device to print to any printer anywhere in the world”.
If you check out Cnet you can find out more about Chrome OS’s Cloud Print system, also the image below shows a rough diagram of how their system will work.
