Printers always "currently offline"

[c.b...@fairrank.de]

We are using Google Apps for business and I want to use Cloud printing for our Cromebook users.  I installed the service on a Windows 2008 R2 Server and installed my network printers. The printers are always ONLINE. Our firewall (Sophos UTM 9) allows https (port 443) and xmpp (port 5222) from internal to external. But everytime my printers under https://www.google.com/cloudprint#printers are “currently offline”. Why! I found many people who has the same problem, but no results. Do I the same installation on another computer with an internet connection without a firewall, everything works fine. Where is the mistake?

Sorry about my English!

I have the same problem with my office, but we run a "Windows" network with a WatchGuard Firebox Firewall and although cloud print worked flawlessly the first few months I had it setup (via my personal workstation on Chrome Browser) it has not worked at all in many months. I have posted about it here many many times and have never once received even acknowledgement by admins of being aware that this is a real problem evidenced by the amount of users who report it. It seems to me as the corporate environment is one where this technology has such great potential that we would get some type of feedback but that is obviously not the case for more that just myself I see. If you are able to get this resolves I would appreciate if you would be so kind to advise what you did and I will do the same. Good luck!

If I find a resolution I will post it here! I´m going to check the whole network traffic on a system where cloup prints works. I hope that I find the problem with this checks.

Can you try manually restart Cloud Print Service using services.msc? Any changes?

If I restart the service over the services.msc the printers are still offline! But if there is a print job under "Print Job" all the print job will print! But the printers are still offline!

That's looks like connector can't talk to XMPP server.

Everybody says to me the connector can´t talk with xmpp. But xmpp ist in my firewall allowed and when I enable the logging, I can see on my firewall the communication.

I made a test on a computer wich is direct connected to the internet. There works everything fine. I installed whireshark and made some tests. But there I did not found any xmpp communication.

xmpp is in my Firewall allowed (Sophos). I installed the connector on a diferent computer which is direct connected to the internet. On this computer I installed whireshark. I recorded the whole communication, but I didn´t find any XMPP communication.

Bahn, can you try to create service debug logs?

Hier a some lines from the debug.log file:

[0115/075801:ERROR:client_util.cc(307)] Could not find exported function RelaunchChromeBrowserWithNewCommandLineIfNeeded

[0115/075802:ERROR:client_util.cc(307)] Could not find exported function RelaunchChromeBrowserWithNewCommandLineIfNeeded

[0115/083547:ERROR:client_util.cc(307)] Could not find exported function RelaunchChromeBrowserWithNewCommandLineIfNeeded

But only this Error is in the debug file. Nothing else. Ore are there more logfiles?

In my next test, I would make a new network behind my firewall, where I can test more settings. I try to get Pidgin running. I think if I get pidgin running (XMPP) the cloud print will work to! And with pidgin I get more information (errors) than with the cloud printing service.

[Vitaly Buka]

It not necessary :ERROR: log message.
