This is a very cool tool. If you are out of your office / home and would like to print a certain document / spreadsheet remotely, you will enjoy using this tool.
You will need to be using Google Chrome and should be signed in with your GMail id and password. Your document should be in your Chrome Browser – you could have opened it from your email or from Google Drive. Your remote computer and printer (at office or home) have to be on ( Chrome will not switch on machines and printers !) Once you go to File – Print, Change Destination, you will see your Home / Office printers also in the list. Select the one you would like to print to, and the document will be printed remotely.
A great tool when you are travelling and want some document to be printed in your office / home.
