Cloud print always reports the network printer as 'offline'.

[ad...@denied.gr]

Hi,

My cloud-ready Samsung SCX-4650 4x21S Series is always shown as OFFLINE in the printers list however, I can print normally.

Tried different routers, DMZ the printer IP, firmware upgrade, and everything else that can be done from my side.

Any ideas?

Thanks :)

Hi, when you say you "can print normally", does your printer automatically start printing when you submit a print job? Or does the printer require a power cycle before printing normally?

I can just fine without a power cycle.

[Robert Toscano]

We determine whether your printer is online by whether its XMPP connection is established. It could be that your printer's XMPP connection is down and the only reason why the printer starts printing new print jobs is because it is polling cloud print.

Is it possible to monitor the traffic in your local network to see if the printer is indeed polling?

I'm not really familiar with network printers and their protocols tbh. Could you provide me some details on the monitoring process?

[evan.ro...@gmail.com]

If I may throw my two cents in I believe OP was referring to "printing normally" as no printing via google. I say this because this is my very problem and would appreciate some advise if anyone has anything to offer. 

If I am sitting at my desk in my office I am able to print to the network HP m602 next to my desk. However, from my iPhone that very printer will show as being "OFFLINE." Over the weekend I spent some time digging around for the issue or even just a fix and was unsuccessful, but I did notice when accessing the google cloud print web based dash board on the very computer I just printed from the printer I refer to for this post shows it has a status is of "OFFLINE." Please advise if you believe you can help. Thanks!

[ad...@denied.gr]

Nope.
I'm talking about google printing remotely.

[215ebr]

That's great! I stand corrected. Honestly, I wish I had that problem and not what I believed you were reporting as I am not able to print over google cloud print. It's very frustrating!

I know the printer works and there are no connection problems because I am literally sitting in front of it and able to click through the file - print menus in whatever application (word, adobe acrobat pro xi, or even a tab in my Chrome browser) on the computer and watch the machine print the job.

What could be the road block here? In fact in my afternoon troubleshooting before getting here I did a fresh setup of the cloud print extension. I disconnected the gcp extension in chrome browsers setting menu and through the gcp web based dashboard I deleted the printer. Subsequently, I started up Chrome and went through the setup successfully (I thought)! Without issue I followed the setup, my available choices of printers to add to cloud print by gcp's list that (I guess) auto populates using the printers your computer has installed on it was displayed showing the printer I am reporting on I chose to add the printer. The setup process then did its thing and was done. No errors; flawless and I believed I was ready to go.

Nope. I went straight to my web gcp dashboard where I immediately saw my printer was "OFFLINE." Seriously? I can't figure this one out for the life of me. Btw, I guess I should mention this is a problem that showed up after gcp working flawlessly for six or more months. Approximately 1 month or maybe even 2 months at this point I noticed when I went to print the printer was not available. Further, I am limiting my report to one printer because I want to keep this simple until it proves to be an issue I need to expand the area of our troubleshooting to cover, but there are 3 printers connected to the gcp account that were setup the first go around with gcp and as I said they all worked without fail for a while. Suddenly, none of the gcp printers are available to print my job. I am stumped with this one....

Please advise? Thanks in advance!

If the Chrome connector is still failing to download print jobs, the most likely cause is that XMPP connections cannot be established with our server.

Could you please provide debug logs?
1. Open regedit and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
2. Find entry with "chrome.exe --type=service"
3. append  --enable-logging --v=1
4. restart computer
5. Signing into windows and wait few minutes. Make sure that printer in still offline in management page.
6. Find  and sent to us file chrome_debug.log from user data dir. See http://dev.chromium.org/user-experience/user-data-directory

It's even better to file separate bug and attach log file there https://code.google.com/p/chromium/issues/entry

Did you find a solution?

I recently got a Canon MG6320 (supports Cloud Print natively). 

It worked fine the day I set it up (with my Nexus 7, Samsung Chromebook, Galaxy S4, and Chrome browser on my MacBook). The next day it stopped working through Cloud Print (showed "Currently offline" at https://www.google.com/cloudprint#printers). 

I restarted the printer, which fixed it in Cloud Print. The next day it was offline again.

I removed and re-added the printer, which again fixed it. The next day it was offline again. 

I forwarded XMPP ports to the printer on my router (an Apple TimeCapsule). I don't think all are needed, but I opened 5222, 5223, 5269, 5298, and 8010 (TCP and UDP for all of them). Restarted the printer and it worked for a day, and then was offline again.

I ran nmap and nettop and didn't see any activity or useful information, but I'm not a network guy and might not be using the right parameters.

During all this, the printer itself has been connected wirelessly (always prints fine via airprint from my MacBook, I can refresh its status and ink levels, etc).

Any thoughts? It's not the end of the world if I have to restart it every day, but it seems like I shouldn't have to do that.

[Robert Toscano]

Just wanted to make sure, even though your Canon supports Cloud Print natively, you were still connecting it through a computer with Chrome on it?

I'll jump into this discussion too! My Canon Pixma 926 is 'cloud ready' and has been registered but goes offline without notice or reason after some time...

It works directly on the LAN and - when it does show up as online - I can print to it externally.

[Robert Toscano]

Could it be that your printer is entering deep sleep mode (during which it shuts off its network connections)? If so, you might be able to turn off deep sleep from the printer's settings.

Hi Robert,

I'm not too familiar with the technologies used on GCP but it still responds to local communication over wireless LAN - from my perspective this doesn't seem to gel.

I'd also be surprised if a printer was made 'cloudprint ready' when it shut itself off from google cloud print every hour or day or whatever - seems to defeat the purpose.

I'll look for deep sleep settings and see how I go, thanks for the tip.

[tlwilki...@gmail.com]

Having exact same problem as Ewan. I have a Canon Pixma MX850 which is online but google reports it as offline. I can print to it with no problems from any of my ipad devices via printopia but in trying to get google cloud printing working find that the cloud printing stuff reports it as off line. 

No idea why. It does go to sleep but any device printing will wake it up and print except for cloud print. Any ideas would be useful. 

[wiest....@gmail.com]

I'm having similar problems with my HP Photosmart 5510, I can print to it wirelessly from my computer, but anything I try to print through Cloud Print shows my printer as offline. If anyone has figured this out I would love to know! 

[jmcq...@trbls.com]

Same problem with Samsung a ProXpress SL-M3320ND Monochrome Printer. The day it was installed it worked fine from google cloud, but it's been 'offline' ever since. I've tried shutting down, reinstalling, rebooting routers, etc. No change. 

I can print via Samsung's SyncThru web service, but not through cloud print.

Same thing with Canon MF8580Cdw. Works fine after restart, but then after some time shows offline again.

Shouldn't be because it goes to sleep - as it was said it defies the purpose.

[adrianw...@gmail.com]

Same problem with Epson workforce 630.  Just keeps going to sleep and needs to be power cycled to print again.  I'm using windows 8.

[hsa...@gmail.com]

I guess I will add myself to this mix as well.  I have a cloud-ready Canon MX-920.  It's wireless and connected to my network.  I can print to it wirelessly from any PC.  I can also print to it from my iPad using Airprint.  But I have to go to it and go into the options and tell it to connect to Google Cloud print server every time.  So if I need to print I do that and it will then show online for a while (not sure if it's hours or days) but sure enough when it's time to print again it will be offline for Google Cloud Print but online for everything else.  It would be nice to have an explanation or a fix. I was going to connect it via RJ45 instead of wireless to see if maybe the wireless times out or something and can be woken up from the other services but not from Google printing - not sure though.

[dlpo...@gmail.com]

My cloud printers are offline as well ... but I think my problem is that I install opendns to keep my kids from going to inappropriate places on the web ... can anyone provide the URLs that need to be unblocked to allow cloud printing?

[jerrym...@gmail.com]

Me, too! I don't see any answers in this long stream.

[Maurice van Kruchten]

Same problem goes for the samsung CLX 3305 FW it stays offline. I have now opened my port 5222 and it seems printing now works, but with a delay of 4-5 minutes. During printing the printer still shows offline.

 The delay is very irritating when I am on my chromebook on my home network. I wish you could just add a normal network printer to chromeos, or improve cloud printing.

[ixtl...@gmail.com]

Same here- Canon MP560 - I printed one time right after I had enabled cloud print, since then everything I print goes into the queue and the printer shows "offline". If I go to my desktops and open the printer utility/or print something then the cloud print files print.

And just to add my situation here, Canon MG5420 and I'm seeing the same behavior everyone has described...if the printer is off or asleep, I can wake it to print from any other function except Google Cloud Print.  Which is annoying, because if I want to print from my local wireless network, I can go over and turn the printer on...but I can't remotely, which is when I most want this feature!

Hi,

Same problem Canon MG6250.  AirPrint OK, Network Printing OK, Google Cloud Print Printer Offline.  As some else has done, if I delete and reinstall the printer on Google Cloud Print it will work until it goes to sleep and then says it is offline in Cloud Print even if it wakes and prints using other methods.

I was having the same problem with my network brother 5250.  I deleted the printer from Google Cloud and the printer is working the way it should.  I can print from Google and FireFox as well as from my non web based programs.  The original problem started slowly, first I had to wake up the computer through a not web based programs such as doing a printer test, then all items spooled in the cloud would print.  That worked for a week, then today there was nothing I could do to get the printer to go online through a web browser until I deleted it from Google Cloud.  My printer was not one of the supported printer but Google Cloud had it listed anyway.  In fact it has listed all printers that are on my printer list.   I hope this is a long term fix.  I have wasted too much time trying to find this work around.

Good Luckj

[redse...@gmail.com]

I am having the same problem I can print from a pc laptop with Chrome, but can Not with HP Chromebook printer says offline on the Chromebook.

[wewantt...@gmail.com]

Canon PIXMA 922 - same problem, offline unless I restart the printer.  Not very convenient and defeats the purpose of cloud printing.

[klumpp...@gmail.com]

same problem here with epson workforce WP-4535 Series. it used to work, but has stopped functioning about 3-4 months ago, no idea why.

I have spent a lot of time on finding out about the problem. nothing works. too bad, gcp is a wonderful idea. in theory...

[kmin...@gmail.com]

Ditto- Canon Pixma MX860 is shown as offline. Printing via the LAN wirelessly is fine.

I also have the same problem on a gcp ready canon pixma. Any progress on this bug?

[PeteKl]

I don't know if this will help, but at one point I kept having problems keeping my Samsung printer (that natively supports Cloud Print) online.  I would try to register the printer again and, after several failed attempts, would finally get Google to see it only to watch it go offline shortly thereafter.  

 

After much frustration, I eventually tracked it down to an ad blocker I had running.  Once I whitelisted my printers administrative web server I was able to successfully register the printer and keep it online.  Apparently the ad blocker somehow interfered with the printer registration process just enough to prevent Google from seeing whether the printer was online or not.  It might be worth a look if you are running an ad blocker of some sort.  

[webm...@khorassan.de]

how can we identify that? is there any specific name? i am using freepdf to print the page as pdf instead to a paper print. will that cause this problem?

[Tom Wilkinson]

So the easy way to get around this which I have not done is whitelist the printer. Maybe the firewall is causing problems. Will try this when I back at the house and see if this does it. Good place to look, had no other places to look. 

thanks
