Google Cloud Print - offline printers

[smurfomatic]

Having issues getting our Chromebooks to print to our Ricoh network printer. Desktops will print fine through Chrome, it's just an issue with Google Cloud Print saying the printer is offline.

 

I'm guessing this must be a network/internet issue, we have a Smoothwall web filter which acts as the proxy server.

 

What I have done:

 

Updated Chrome on the print server

Installed the Cloud Print service

Updated printer drivers

Restarted server and then tried all of the above again...

Did you get anywhere with this?

[smurfomatic]

The only solution we have found is to republish the printers. Unfortunately this has to be done every time the "host" machine is restarted!

Thanks for the info.

Is TCP 5222 (Outbound) open on your firewall? If not you will have issues with printers going offline.

[smurfomatic]

It only goes offline if the host PC is rebooted. Can't see this is a network issue as it can vary from hours to weeks between reboots sometimes

[rpettit]

I have - We have smoothwall and I have added the port 5222 TCP to the outbound port for all users

Just reporting my experience. As soon as that port was opened all the issues disappeared. It hasn't happened since.
