Unable to communicate with time clock across VLANS

I have a situation where i am installing SGE2000Ps to replace my old switches and configuring VLANS. The time clock will not communicate across the VLANS. If I unplug the network cable and plug it back in I will get two successful pings. If i use a PC configured with the same network settings as the time clock and plug it into the port for the time clock it communcates fine. Have any one come across this problem?

Hi Wayne,
Thank you for contacting Cisco Small Business forum.
I am sorry that you experience this issue.
I have a question for you. What is providing clocking on your network?
The switch operates only as an SNTP client, and cannot provide time services to other systems. So, you can configure it time manually by going:
System > System Management > Time > System Time;
To avoid any issues on your network. I would suggest to use one common SNTP server for all of your network devices. On the switch you can configure it here:
System > System Management > Time > SNTP Settings. If you do not have SNTP server on your network, you can use publicly available one.
Let me know if that helped.
Sincerely,

Unable To Communicate With Printer HP Officejet Pro 8600 (Network)

I recently purchased an HP Officejet Pro 8600. One morning a couple weeks ago I tried to print something and I received a prompt saying "Unable to Communicate with Printer (Network)". I turned off the printer and turned it back on which did not help, I then turned off my wireless network, turned it back on and still nothing. I finally figured out that I first have to turn off the printer, then turn off my wireless router wait thirty seconds, turn the router back on and the turn the printer back on. After these steps my printer was working. The next morning the same thing happened "Unable to Communicate with Printer (Network)" and I've been replaying Groundhog's Day ever since.
Please help!

Hello msheehy-
I would like to help you with this issue. It sounds like the router is changing the ip address of the printer. This could be caused by a couple reasons. (ip lease time, power loss to the router) I would recommend looking at the following link. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03781399&cc=us&dlc=en&lc=en&product=4323648&tmp...
I think if you would set a static ip address in the printer EWS you would better off. I hope this helps.

HPlip: "Unable to communicate with the device" error

Hello Arch Community, I've been a user of Arch for a while and most of it just worked out of the box. However, I had my HP 6300 working through a direct connection. But a couple of days ago it just broke.
I've tried everything I could think of to make it back but all has been unsuccesful, I removed the printer and tried to add it again (sorry, old Windows habit, there most of the time works), however, I couldn't add the printer, it fails with the error: "Unable to communicate with the device. Please check the device and try again.", I added myself to the ld group (shouldn't matter, but I did it anyway)
I have cups 1.4.2.

Albeit it has errors, I can't see how they are releated (cups does have a conf file, but it seems that *my* user can't access it, expected 'couse it's owned by root). Any ideas?

Hi
I had the same problem. The solution is to change the network discovery mode to SLP or add manually the IP address of your printer at the first step of the hp setup wizard. After you install the printer successfully, check the maximum resolution of the driver. Mysteriously, for me the maximum resolution was restricted to 600 dpi so I downgraded to the previous version of HPLIP and got back the 1200 dpi option. Please let me know if you have this issue too. I have posted this question in the hplip forums, but I haven't received any replies yet.

HP Officejet 7500 E910 Network. When asked to print "Unable to Communicate with Printer"

My printer has been functioning well for some time. When my some installed a new wireless modum I would often receive the error message "Unable to Communicate with Printer" but it would blink a few times, then connect and print. As of three days ago I receive that message when trying to print from both of my laptops. I am wireless and have checked the wireless signal and it is strong, The wirless connect symbol is lit on the printer. I ran a wireless Network Test Report on the printer and the results indicated no problems.
The printer woks if I use it manually to print or scan. Neither printing nor scanning work when command is sent from my computer. The Wireless Network Test Report printed fine. Interesting though the Wireless Network test Report had the following date: Jan-00-00 00:00AM.

Hello @Dalead,
Welcome to the HP Forums!
I understand you're receiving a message stating "Unable to communicate" when printing a document using the Officejet 7500 E910. I will do my best to assist you! I would recommend following this entire HP document on Printer Does Not Maintain Wireless Connection.
Try assigning a static IP address and let me know if this resolves your issue or not. I will be looking forward to hearing from you. Have a great night!

Unable to print/scan- unable to communicate with printer message

I am unable to print due to a unable to communicate with printer error messaege. I was previously able to print just fine( a few hours a go) the IP addy has not change. The printer is connected to the network and able to download updates etc just fine. The printer is connected but they just wont recognise each other. Print and scan doctor was a complete waste of time, it showed the printer insatlled but then could not connect. Can someone please help getting so very frustrated with these products. Printer is the 6700 All in one series and laptop is Hp Envy.

Hello @leilee , and welcome to the HP Forums, I hope you enjoy your experience!
I see you're experiencing connectivity issues. I would like to help!
I would first recommend a power reset. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
I would then recommend utilizing this document on Wireless printing center Troubleshooting Issues.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

HP 7520 All in One "Unable to Communicate with Printer" msg

We have a HP all in one Photosmart 7520 printer- it is USB connected to a mac (OS Snow Leopard I believe). This was the original set up. When I moved back here I was able to set up a wireless network with the mac as the host computer (connecting the modem to a Linksys router). I was able to set up my windows 7 PC to this network and to the printer with no problems and was able to print to the printer for months. Now I am getting this error "Unable to communicate with Printer" and says it is unable to to be completed because the printer is unavailable or not connected.
The printer IS connected and on. My PC can see the printer listed in the control panel (I in fact uninstalled and reinstalled to see if that would fix the problem- it didn't). The only thing that has changed since I originally set this up was that I added my second PC (Windows XP) to the network but I don't think that's the cause of my print job requests failing to print.
I do know that the modem itself has been reset a couple of times due to the cable deciding to drop out a couple of times. Could this be the reason why?
What else can I look at to try to get my PC to communicate fully with the printer. I've tried printing from googlemaps as well as a short notepad file.
Thanks!
This question was solved.
View Solution.

Let’s try this.
1. Verify in the printer that 'Auto Off' is disabled. Use the Embedded Web Server (EWS) by going to the
    printers IP address in your browser, Settings Tab/Auto Off. Or use the Printer Assistant, Printer Home
    Page (EWS).
2. Set a static IP in the printer outside the DHCP range of the router.
In the router:
3. Use a fixed wireless channel like 1,6 or 11, never 'auto', try channel 1 first then the rest.
4. Set router to 20Mhz only, or 145Mbps depending on router.
5. Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode.
6. For the routers security, disable WPS and never use it and disable UPnP so nobody can hack your
   system (if you want to know why, search the web).
7. If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same,
   they must be different for all bands, even for any Guest networks.
8. Save all settings. Power off both, wait 5 mins. Power on router wait 3 mins.
9. Power on printer and verify it reconnects to router.
Windows 7/8/8.1   Is Network Discovery on or off?

Unable to Communicate with Printer message, but still prints

I installed a new ENVY 4500 printer on my Windows XP system. and it there are two problems:
1. when I try to print, it tkes some time, then a message window appears with "unable to communicate with printer", but it still prints. I have uninstalled the printer and the drivers and reinstalled, but to no avail.
2. I have a Seagate GoFlex USB backup drive attached. However, when the printer is connected, the Seagate drive disappears. It happily coexisted with my former HP C4100 printer for years, but the new one seems to cause problems.

I solved the problem. I purchased a new USB cable for the printer. I deleted the printer, uninstalled the print drivers, and completely reinstalled the printer. At first the installation did not work, but I discovered the USB cable was not completely inserted into the printer. Initially it felt like it was, but I gave it an extra push and it clicked into place. At that point the installation completed successfully. Now the printer and the Seagate drive work properly.

Unable to communicate with printer via WiFi

Laptop is not recognizing printer, stating "unable to communicate with printer at this time. ! No Printer Selected".
There is only one printer and only one to select from.
All other laptops, iphones, etc communicate FINE!
It is just THIS puter unable to print. Printer is HP Photosmart C410 All-In-One Premium Fax.
Router, modem, etc all functioning properly. PRINTER functions properly.
This has gotten VERY old! Brand new MacBook Pro!
OS X 10.9.5

Are you receiving any error messages when you print from the desktop? Its possible the print spooler is having issues which is not pushing the jobs to the printer. Lets restart the print spooler to get any old jobs that could be stuck in the queue removed.
1. Press the start orb in the bottom left on the screen.
2. Click on "Run"
3. Type "services.msc" (without the quotes)
4. Locate the Print Spooler service in the right column
5. Click restart on the service link on the left
After it restarts the spooler go ahead and retry printing. Let me know if this works.
Thanks,
Sean

HP Photosmart 5520 Unable to communicate with printer

I have had a HP Photosmart 5520 for a few months that I am NEVER able to print wirelessly from Windows 7 PC's after it has been sitting idle for a period of time.
When the printer is first powered on everything works great.   I have two HP Win7 laptops that will both print to it with no issues.   However, if the printer has been powered on for some time and I try to print from either of these PC's, I get the "Unable to Communicate with the Printer" message below from the printer software running on the PC.
However, the printer appears to be working fine on the network for every other debug test I do while it is in this state. For example, if I open a command shell on the same PC and ping the pinter IP, it responds just fine.  I also put the known IP address in a browser window and the printer serves up the status page with no issues. The status page confirms the IP address is correct and says that everything is working fine from a connectivity standpoint (see pics below). Still, it won't print.
If I simply turn the printer off and then turn it back on, all pending jobs are printed. Any subsequent jobs that are printed also print w/o issue. However, if the printer sits idle for a short period of time it is right back in the same state! Please help, this is very frustrating!!
The behavior is the same if I (1) let my router DHCP server assign an IP address, (2) configure the DCHP server to always provide the same IP address to the printer MAC (which it was doing anyway), or (3) configure the printer to use a static IP address.
I am using a Netgear WNDR3700v2 wireless router firmware v1.0.0.36 (the latest).   Details about the printer, printer firmware version, printer network setup can be found below.

I changed two settings related to WLAN inside my router (see detailed feedback below). I doubt that they will have an impact,, but will report back with what happens.
The reason I do not think it is related to the connection to the printer is becuase when it is in a state where the PC can't print to the printer, I verify the connection is OK by pointing by browser to the ip of the printer. It works just fine....
The reason I don't thing there is anything set up wrong on my PC is because when it is in this "bad" state, I can simply power cycle the printer and the jobs stuck in the PC print spool all go through.
1. Set a static IP in the printer (see step 6) outside the DHCP range of the router (check your manual).
Previously tried (still configured this way)
2. Verify in the printer that 'Auto Off' is disabled. Use the Embedded Web Server (EWS) by going to the
    printers IP address in your browsers address bar, click Settings Tab/Auto Off. Or use the Printer
    Assistant, Printer Home Page (EWS).
Previously tried (still configured this way)
In the router: (Refer to your router manual for information)
3. Use a fixed wireless channel like 1,6 or 11, never 'auto', try channel 1 first then the rest.
Changed this.
4. Set router to 20Mhz only, or 145Mbps depending on router.
I don't know what this is. Is it related to the Wireless throughput? (I have 2.4Ghz bans set "up to 54Mbps", 5Ghz band set to "up to 300Mbps")
5. Always use WPA2-AES (Personal) encryption, but you can try ‘mixed’ mode.
Already using this configuration
6. Disable WPS and never use it and disable UPnP for the routers security. Nobody can hack your
   system now and helps with wireless connectivity (if you want to know why, search the web).
Already using this configuration
7. If you have a dual band router (2.4Ghz and 5.0Ghz bands), make sure the SSID’s are NOT the same,
   they must be different for all bands, even for any Guest networks.

8600 - unable to communicate with printer error

I bought a 8600 about 6 months ago. The printer worked fine for about a month... then my XP and now my new WIN7 machine keeps getting a connection error (was hopinp the move from XP to WIN7 would resolve). My windows 8 Surface has no problem. The issue will go away very temporarily if I reboot (here is the irony - HP's print doctor app can see my printer - and the "fix" is to reboot - sorry HP, rebooting every time I need to print is no an acceptible fix).
Printer is on. Router is fine (note that the WIN8 machine can print while the WIN7 machine is providing an error). If I update the IP address as noted below (note the IP address has not changed), there is no possitive effect on the issue, but the connection is confirmed durring this process - but still get the error when I try to print.
Full text of error message:
! Unable to communicate with Printer
The print job could not be completed becuase the printer is unavailable or not connected. Check your cable or wireless connection, and make sure the printer is powered on and ready.
If you installed this printer by IP address, then you might need to update the IP address. Us the update IP address item in the Start menu entry for this printer....

After tons of searching, misguided efforts from HP "experts" trying to point at the router - I think I found the solution in bvwjm's post.
his/her comment:::
I changed the port address in Printer Properties that Windows was using to find the printer, from the HP network rediscovery port monitor, to my assigned static IP address with port type "Standard TCP/IP Port".
I am finally able to print - no reboot! I will cycle a few times and see how it does for a week, but allowing "printer pooling" and adding the port - matching my IP address on the printer seems to have solidified things.
Re affirms my posts on other errors like this - it is not a router issue as the HP experts point the finger away from HP

HP Officejet 6700 "unable to communicate with printer".

Before I left on vacation, the wireless printer was working fine. Now I get this error message. I have disconnected and reconnected everything. I have run the diagnostic tests and the wireless network checks out fine. I have tried everything in the troubleshooting guide to no avail. I think it's probably a setting somewhere, but I can't figure out where. Help!!!!

I have the same problem with an HP OfficeJet 8600 Plus.
It worked last week, this week it gives "Unable to communicate with printer" on both of our PCs (XP, Vista).
I have tried all of these:
Rebooting router
Rebooting printer (5 times)
Rerunning the wireless setup wizard on the printer (3 times).
Start menu > HP OfficeJet Pro 8600 > Update IP Address (3 times)
Download & run latest HP Print and Scan Doctor (connected via USB cable) (once)
On the print & scan doctor, it gave no errors or warnings, and appears to have completed successfully. Nonetheless when I clicked on 'print test page' from within the HP Print and Scan doctor, I still get the "Unable to Communicate with Printer" popup box.
On the 'HP Hardware DIagnostic Utility 3.1 "Wizard" tab, Connectivity and Device Status bogh gave green checks, and, the 'Print Test' WAS SUCCESSFUL in printing a page from within that utility. Hardware DIagnostic Utility 3.1 completed with all tests marked successful. All other printing still fails, e.g. regular printing and Windows 'Print Test Page' still fails with the Unable to Communicate with Printer error.
The HP Hardware Diagnostic Utility 3.1 'Printer Data' tab says I am running Firmware Version CLP1CN1232AR, Born On Date 10/3/2012, Software Version 25.0.169.0, Printer Driver Version 06.64.00.994.
My printer is less than 1 year old -- has it died/shoud I start up the warranty process, or is there something yet to try?

HP Officejet Pro 8600: "Unable to Communicate with Printer" error message

I receive the error message "Unable to Communicate with Printer" regularly when I print. Sometimes it will print 3 or 4 times just fine before I get this message. Sometimes it happens my first try at printing. I then have to reboot my computer to get it to work again. My OS is Windows 7 and my printer is an HP Officejet Pro 8600. My printer is wired to my computer. I have tried re-installing the printer software but this did not help. I've had this printer for only four months. Started happening after the second month. Any suggestions?

I finally solved it. Reflecting back on previous message boards I decided to try one last time. Some posters have found the problem in the Antivirus, Firewall protections. (By the way, I had even upgraded my router with no luck).I have Norton AntiVirus provided by the cable company.1. I turned off everything in the firewall. Although this left me vulnerable for a few mintues, I needed a fast test.2. It worked! I was able to print something immediately.3. I went back into the firewall, turned everything back on but turned off an individual switch within the firewall that said to "share the printer. "4. After turning it off, I was able to print and still have the most important parts of the firewall.This ultimately met my needs.Perhaps HP could:1. Do a better job at beta testing prior to release, including various brands of firewalls. Is there even a beta test process?2. Provide a better description of the error since all indicators within the drivers say the printer is connected. There should be a message indicating that it's connected but unable to print due to firewall protections.

Unable to Communicate with Printer Error - Officejet Pro 8600

My printer was working fine last week... printing from my Mac desktop via wireless.
Now, when I try to print, the progress window is just hanging... trying to find the printer.
I deleted the printer in my settings and tried to reinstall. Now, I am getting an error message that says: Unable to Communicate with the Printer at this Time.
Help, please!
Comuputer: Mac OSX Version 10.9.3
Printer: Officejet Pro 8600 Plus... only about 3 months old!

Hello K_D123, and welcome to the HP Forums, I hope you enjoy your experience!
I see you are having wireless issues. I would like to try and help.
I would recommend powering off your computer and printer. Once they are both off, I would unplug the power from the back of your wireless router, wait 60 seconds and plug it back in. After the router has begun broadcasting, power on the printer and computer.
I would also recommend following the steps in this document on Wireless printing center Troubleshooting Issues.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

Error: Unable to communicate with the Reports Server

The configuration I am working with is:
* Oracle 8.1.6 DB on a Unix machine
* Oracle Reports 6i on an NT machine
* Microsoft IIS web server
I have successfully tested my reports during the development phase of my project. Unfortunately, now that it is considered production and is available to upwards of 30 people, I am getting the following error message after verifying the server is up and after a numerous reports have been served:
Error: The requested URL was not found, or cannot be served at this time.
Oracle Reports Server CGI - Unable to communicate with the Reports Server.
After receiving this message I noticed that the Report Server service is down and the log only indicates that it "shut down immediately". (no ORA messages) I tried restarting the service, but after serving one report, it would shut down again with the same message.
I am wondering if it is a problem related to the cache. I used the default of 50M in the config file, but when the cache directory reaches 50M, the problem seems to appear. I then deleted approx. 30M of files from the cache directory and the Report Server service appeared stable. I changed the cache limit to 1M to see if there was a problem with the cache being so big. All appeared well for the first few hours of operation but then the Report Server service shut down again and upon restart crashed within a minute or two (usually as someone tests a report, it crashes again).
Do I have a configuration problem? Has anyone seen this problem? Thanks in advance.

Hi,
I just found out that if i give
http://localhost/cgi-bin/rwcgi60.exe?key1
where key1 is a key mapping file that contains the report name,username and pwd for the database and desformat...etc..
the report pulls out fine with the correct data..
i am stunned...
while none of the other commands like
http://.../rwcgi60.exe
or
http://..../showenv?server=repserver
or any other usual command doesnt work...
anybody faced this before??
Thanks.

VIPCA problem: PRKH-1010 : Unable to communicate with CRS services.

I have installed clusterware across 2 nodes recently in a virtual environment. I have been following a guide on how to do this and everything has gone as expected apart from when i try to run VIPCA manually (as detailed in the guide). When trying to run VIPCA on node 1 i get the following error:
C:\Documents and Settings\Administrator>cd c:\oracle\product\10.2.0\crs\bin
C:\oracle\product\10.2.0\crs\BIN>vipca.bat
PRKH-1010 : Unable to communicate with CRS services.
[OCR Error(Native: prsr_initCLSS:[21])]
PRKH-1010 : Unable to communicate with CRS services.
[OCR Error(Native: prsr_initCLSS:[21])]
PRKH-1010 : Unable to communicate with CRS services.
[OCR Error(Native: prsr_initCLSS:[21])]
C:\oracle\product\10.2.0\crs\BIN>
I was wondering if anyone had experienced the following error before and might be able to shed some light on why I am receiving it and how to resolve it to get VIPCA to run properly.
Cheers Edd

Followed a metalink note which told me to use opmd.exe to set all the services created by oracle to manual. this utility also created a new service - Oracle Process Manager, which i take it controls all the other services that clusterware uses.
This is working fine however the OracleCSService is unable to start, it simply hangs at 'starting' and doesnt do anything from there... this i think is the route of my VIPCA problems, so if anyone knows how to sort this out that would be great.
