Tested beginning of this year Google Cloud Print to be able to print from Android tablets running our hospital management system. Installed the server part, the printer drivers, everything by the book. Didn't work well. Issues with not showing the proper paper sizes, general unreliability of the service, and all that jazz. Reported it as an issue on their github page, but their developers were silent.Others reported the same issues, or even worse. It quickly became obvious we were milking a dead cow. At least it's official now.
