This starts the cloudprint service if you go to the [[https://www.google.com/cloudprint?user=0#printers|Cloud Print Control Panel]] as user **user@domain.com** you should see the printers from your local cups server. This command will not return the terminal so we will need to add a script for that. | This starts the cloudprint service if you go to the [[https://www.google.com/cloudprint?user=0#printers|Cloud Print Control Panel]] as user **user@domain.com** you should see the printers from your local cups server.

+ | ==== Notes ==== | ||
+ | Using ssh was the only way I could get cloudprint to work on startup. I also found that after a few hours cloud print would stop working. I found if I restart chrome every hour the problem went away. You might want to have cron run **ssh root@localhost "/scripts/restart_cloudprint.sh"** every hour. |
