Does eprint software communicate with computer it is installed on using port 443?

I have eprint installed with laserjet 551 dn color printer. My computer has 64 bit windows 7 installed. My firewall had issues with the software when https inspection was turned on (Microsoft Forefront TMG). If I exclude the printer client(IP address of printer) and the domain name of *.hpeprint.com the software will connect. After a number of days the connection is lost and can be restored for a few days again by disabling https inspection and refreshing at the hpeprint center. It is likely the eprint software is trying to communicate with my computer over port 443. Does anyone have information on this? If details are available a listener could be set up for the protocol on the firewall to mantain the connectivity without disabling https inspection.

The ePrint Software (www.hp.com/go/eprintsoftware) operates on the following
Print job communication and transfer:
● Print jobs are transfered from the HP ePrint Software to the HP cloud eprintcenter.com through HTTPS (Oauth
authentication).
NOTE:  if you are sending emailed print jobs (ie- not using ePrint Software) eprintcenter.com would accepts the SMTP print jobs, which depending on your setup might leave your host via POP3, IMAP, etc
● The HP cloud sends notification to the HP web enabled ePrint device of the pending print request through XMPP—an
XML-based messaging procedure.
● The Web-connected printer authenticates to HP ePrintcenter cloud to receive the pending ePrint requests in queue. The
ePrint device establishes an HTTPS connection and downloads the job(s)

  • Software necessary to communicate with Ipod not properly installed

    Hi,
    I updated my Itunes software and have been having problems ever since. Every time I connect my Ipod I get the message: "Software necessary to communicate with Ipod not properly installed. Reinstall Itunes..." After I click Ok it goes to Itunes but it does not recognized the Ipod. Now I have reinstalled several times and even downgraded to a previous Itunes version but keep getting the same error. Even though I don't know if this has anything to do with it, yesterday I noticed that I cannot watch any YouTube videos either, i get the error: "Hello, you either have JavaScript turned off or an old version of Adobe's Flash Player. Get the latest Flash player" Any help would be highly appreciated!

  • Ichat is not working.  tried using port 443 and still does not work

    ichat not working.  tried using port 443 and i stay on for about 45 seconds then it disconnects.  Can you help?

    HI,
    Can you tell me the make and model of your routing device.
    The 10 Second error message is caused by a break in the connection.
    This could be the Wifi being dropped (if you are using WiFi) due to interference from other nearby routers.
    It can be dues to setting or features of the router and if the experience has changed that could be due to a speed increase in your internet service.
    If you are using Ethernet and having this issue it is much more likely to be a setting/feature issue.
    Examples.
    Netgears.  These have a separate WAN set up page that lists either DoS or SPI as one of the things that can be Enabled or Disabled.
    Linksys.  If your model has a Security tab and this has  Firewall then DoS and SPI are port of this.
    Netopia devices Tend to have a 4 level Firewall which DoS and SPI are part of the two highest settings.
    DoS = Denial Of Service and is a Threshold based "Protection" Feature.
    it judges whether too much data is being sent to you  (it was designed originally to stop people overloading Web Servers (many people, many refreshes).
    iChat can outstrip the setting with most Internet Connections in most part of the world.  (In fact iChat can send more data than most Video Streaming sites)
    One thing you can do that may get around this is to reduce the Bandwidth used in iChat (iChat Menu > Preferences > Video Section > Bandwidth Limit drop down)
    Try 500kbps

  • How does Oracle client communicate with a database server

    Looking to idenify how Oracle Database Client for OpenVMS communicates with database server and whether the protocol used is secure. Realize that it is using whatever the configured network protocol is (ie. tcpip) but is languauge it uses ( ie. SQL, etc..)  secured/encrypted and if not what steps can be taken to encypt

How come this values reset to null? What is causing this to reset?Nothing in this has anything to do with the sever. You need to check what the client did on his machine that caused registry to get modified?
    How does oracle ODBC works with Oracle database? Need to know all the steps involved?The connectoin from any client is initiated by a client process. This client process is supposed to get a server process to do his work. So if this is done, the client can work now with oracle . Please see the concepts guide for the gory details of the entire process.

  • How does AirPort Utility communicate with remote/relay AirPorts?

    1. Wireless case: Does the AirPort Utility always try to communicate with remote/relay AirPorts directly, or does it use the network WDS when another AirPort provides a stronger signal? If it's the former option, this might explain why people have problems sometimes configuring distant AirPort base stations in WDS setups. If it's the latter option, problems with configuring a distant AirPort might be caused by improper configuration of the AirPort providing the strongest signal (presumably, the nearest).
    2. Ethernet case: When one attempts to configure an AirPort via Ethernet, does it matter whether the AirPort is configured to connect to the internet via Ethernet (vs. wirelessly)?

    Thanks for the replies Bob

  • WRT54G - Changed user name and password; now printer won't communicate with computer

    Time Warner used remote access to get into my wrt54g system and create a new user id/password for security.  As a result, my hp printer will no longer communicate with my computer.  HP says to hook up a usb from router to printer, but there's no usb port on the wrt model I own.  Don't know whether to buy a new router or if there is a solution to this problem.  I hooked up a usb from computer to printer but it did nada...

    so meaning to say you are unable to print even if the printer is connected to the computer. If that's the case even if your printer is connected wirelessly to the network then you will still not be able to print. Make sure that the printer will be able to print first when connected to your computer.

  • How does the WCS communicate with the 4402 controller ?

    I would like to place the WCS server on a different vlan than the controller. How do they communicate ?
    Regards
    J Folkestad

    Hello,
    WCS communicates with the controller mainly through SNMP and HTTPS. You will find a list of protocols used on CCO
    http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a00806f070a.shtml#portswcssvr
    So no problem to have WCS and controllers management ip addresses on two different subnets.

  • Unable to communicate with product message when installing laserjet cp1525nw printer

    I have a cp1525nw wireless printer that use to work fine wirelessly.  I changed my router password (linksys router) and now can't connect.  I have tried changing the password back to the original password and it still will not connect.  So I when back to the changed password.
    I have tried resetting the printer to the default settings, removed all HP software, deleted all temp files, rebooted machine and attempted to reinstall the printer.  The software loads fine, I've connected the USB cord and then get the dreaded "Unable to communicate with product" message.  I have previously tried to connect by WPS and that didn't work either.
    The Wireless Network Test Report shows that the Network Name Found test is Fail.  The Network Summary report shows a different Network Name under the wireless Network Configuration section than my network's SSID.
    What do I need to do?

    Hello,
    I see that you are having issues setting up the printer over the wireless network. I will certainly do my best to help you.
    The password might not be recognized by the printer, if there are spaces or special characters in it.
    Restore the printer defaults. Press the OK button, select Network Config, then select Restore Defaults.
    Print a configuration page to make sure the SSID and the IPv4 address are cleared.
    Printing a Configuration Report.
    Run the printer software again and select Add a Device to setup the wireless again.
    If you are having issues, then uninstall and reinstall the software to configure the wireless.
    Uninstalling the Printer Software.
