ePrint & Print Apps connectivity troubleshooting steps - please review before posting

 

This information below is provided to help you troubleshoot connectivity to web services to enable your printer for printing with ePrint, launch/use of printing applications, enabling the web services, print your sheet of info from web services or add your printer to your account on the HP ePrintCenter.   Only the items that actually show to solve client's problems have been included in the list.

For best results of review and apply the applicable steps below in the order of presentation before posting a request for help in the forum, so that members of the forum who respond to your message can provide the best possible assistance.

Also see this post (http://h30434.www3.hp.com/t5/ePrint-Print-Apps-Mobile/Start-here-Web-Services-How-To-and-Troubleshoo...) for additional "How-to" and links to important information, FAQS, web and content assistance services.

Before you apply the troubleshooting below information:

If you receive an "Invalid Code" message when you try to add your printer to your HPePrintCenter account, but do not have any other problems with ePrint and Print Apps, you probably only need to reprint your web services of your printer info sheet.  Your printer to claim the code that is printed on the sheet of information can be used only to add your printer to your account of ePC for 24 hours after the printing of the information sheet.  Reprint of the information sheet does not alter your code claimant, it reactivates just your printer to add your account to the ePC for 24 hours.  See herefor the stages of re - print your web services info sheet.

If you have enabled Web Services on your printer, but Web Services info sheet containing your printer of the pretender code does not print, your printer is not fully completed its registration of web services and don't ePrint emails will not print or print app content.  In this case, you will not receive the error messages on the printer and you can see the e-mail address of your printer on the display on the front panel of the printer.  If your Backgrounder web services print no less than five minutes of activation of web services, try removing and enabling web services.  If your Web Services info sheet does not always print after the reactivation of web services, you will need to wait and try again later.   If you receive error messages when you try to enable web services, continue to web services connectivity troubleshooting steps below.

If you have the email ePrint which are not printing, make sure you first you confirm your emails meet the requirements of format/attachment ePrint.  Review the requirements of email ePrint in the ePrint Help/FAQ on HP ePrintCenter to www.hpeprintcenter.com.  You can also view connectivity status and ePrint job list your printer on HP ePrintCenter if you have created an account there and added to your printer.  (Always use the button "Refresh" on the page of the EPC, not your browser refresh button to display the printer connection status updated on the HP ePrintCenter.)

A. of the simple steps that can be surprisingly helpful - try these first:

  1. Check the operation of the internet access of your network - on a computer connected to your network, to use a web browser such as Internet Explorer or Firefox to view a web page.  If you can not access the internet your internet service provider may have a problem that affects the ePrint/Print Apps.
  2. Go to HP ePrintCenter and look in the section News (http://h30495.www3.hp.com/news/ ) to see if there is any updates the service status.  In some cases, you will have to just wait a few moments and try again.
  3. Reactivate the wifi and then on your printer and wait a minute for your printer to reconnect to your network
  4. Reset your printer - turn the power off, then on) and wait a minute for it to reconnect to your network
  5. Restart your router - disconnect the power cord to the back of the router, wait a minute and then plug it back and wait at least one minute for the power on router and all of your devices to reconnect.

B. check your printer's IP address to confirm it is connected to your network.   

Verify that your printer has a valid IP address (for example, typically 192.168.x.x network home wireless) by displaying the network settings screen on the view menu on the front panel of your unit in a network or wireless, or by printing a printer status report (usually located on the Tools menu).  If your printer does not have a valid IP address, re-run the process of network for your printer configuration.   For more help, setting up or troubleshooting of connection of your HP printer to a wireless network, go to http://www.hp.com/go/wirelessprinting

C. confirm that your printer and your router is up-to-date firmware:

 

Software update on your printer or your router is important to use web services.

  1. Make sure you have the latest firmware (FW) for your printer by checking the updates of product, usually found under the 'Web' or 'Preferences' menu of your printer options.  If your printer detects an update, but is unable to complete the download/installation, ensure that your router FW is up to date and try again.  If your printer continues to fail complete the download of a FW update available, continue to "Set E. a manual IP/DNS server' below.
  2. Make sure you have the latest firmware for your router - review your router documentation/help (or the web site of the manufacturer of the router) for more information on how to to check for and install the firmware updates.

    Failure of temporary connection of the resolution after the printer firmware update

Some printers may experience connection failure after the firmware upgrade.  It is because the printer restarts automatically after firmware updates and needs to restore the network connection.

  1. Check that the printer has been given a valid local IP address by your router (for example. 192.168.x.x if DHCP is used) before trying to access applications or print using ePrint.   You can see the IP address of your printer by going to Setup wireless or network printer.
  2. If you do not see an IP address, you may have to restart the printer.  In some cases, you may need to remove and re - enable web services to reestablish your connection.
  3. See the section FAQ & help HP ePrintCenter for more information on how to remove and re - enable web services from your printer.

Let your printer enough time to reconnect to your network after you have tried all the steps above, before trying new ePrint to Print Apps.

D. Remove and re - activate the Web Services and Restore Factory Defaults

  1. Delete and then reactivate web on your printer services.  If the Backgrounder web services does not automatically print within minutes of the reactivation of web services, web services, has not been fully activated on your printer.   You should maybe wait and delete and re - enable web services again in a few hours to allow its issues of your printer communication with cloud servers to clarify.  Until a backgrounder web services print your record of web services is not complete.   Follow these steps if your printer is connected to the Internet.

 

Photosmart: Web Services to delete the option is available under configuration > Wireless > Web Services or to the configuration menu option > option, Web site or via the icon ePrint on the front panel of the printer.

On the station click on the Menu button on-screen station (to the right of the Home and Back buttons at the top left when the display is anchored on the printer); Select settings;  Select "Web Services." Check the box "Web Services".

OfficeJet: use installation > installation of Web Services > restore factory settings to remove the Web Services of the printer.

LaserJet: print a configuration page of your printer to find the IP address. Open a Web browser and type the IP address of product in the address field. The HP integrated Web server will open. Click the HP Web Services tab select the option to delete Web Services.

2. restore Factory Defaults on your device.  If the withdrawal and the reactivation of web services does not solve the problem, restore the default settings on your printer and try again.  The factory default option is usually located in the Setup > menuOutils on your printer.   Follow these steps on your device:

  1. Remove/disable Web Services

  1. Restore the values by default/factory settings (depending on the printer, it is under Setup > Tools menu or configuration > menus Web Services, but varies depending on the printer)
  2. If you are prompted, redo initial setup of your device and add it to your network
  3. Re-enable Web Services
  4. Once the Web Services information sheet printing, use the printer claiming the code to add your printer to your account on ePrintCenter

E. set a manual IP/DNS server settings of your printer

Set a manual IP address/DNS Server on your printer will solve web services connectivity problems that may occur on some networks with some routers.  Note: Assigning a manual IP/DNS server may be particularly useful on networks using routers DSL/VIOS.

Please read the instructions below before their application.  Do not try on your own if you do not understand networking basics.  Most of us have a member of family/friend/boyfriend 'techno '... If you are not comfortable, it's maybe a good time to call him or her, or contact HP support to help you.

Before you begin, first remove Web Services of your printer if it has been activated.  (See section 1. D. above.)   Removal of web services will delete your printer from your HPePrintCenter.com account (if you have already created an account and added).  When you reactivate the web services after you complete these steps you will have a new ePrint email address and need to add your printer to your account of ePC again.

How to set a manual IP/DNS server address on your printer connected to the web:

  1. Print a network on the front of the printer Configuration Page.  On some printers, this will be under wireless > settings wireless and other models, use the option 'Print report' of the status screen accessed from the icon on the homescreen printer wireless wireless.   Note IP of the printer address that is listed in the IPv4 of the report section.  On most printers, you can also see IP address of the printer in the menu Wireless, or on the wireless status screen.
  2. Type that address in the address bar of your browser (where you would normally type a web page URL) and press enter - it will load the internal settings of the printer page (also known as the integrated Web server or EWS)
  3. Select the tab 'Network' or 'Networking' (the label varies depending on the printer) in the tabs at the top of the screen in the SAP

Depending on your printer model, the next les prochaines etapes steps varies:

  1. Select the option 'IPv4' along the left side of the screen of networking
    or
  2. Select the option 'Networking' on the left side of the screen
  3. Then select the 'network address (IP)' on the left side of the screen

The screen that find you should be display "IP address Configuration.  This screen allows you to choose an automatic or manual (i.e. fixed) address your printer's IP, but also the values of subnet mask and default gateway.   You use this screen to set a manual IP address and the DNS server for your printer.

To continue:

  1. Select the radio button next to "Manual IP"
  2. Select the option '"suggest a manual IP address' below the IP address fields.  Manual IP address fields will be automatically filled with the values suggested after a few moments.
  3. Select the option "Manual DNS Server" in the section Configuration of the DNS addresses
  4. Enter the address just entered the 'default gateway Manual' in the field 'DNS server preferred manual. "  The entrance to the "Alternate DNS Server Manual" leave blank.
  5. Carefully check the values you entered to make sure they are all correct.
  6. Click 'apply '.
  7. Save all open documents and close all web browsers on all computers
  8. Power off the printer and unplug the router.
  9. Plug in the router, wait so that it starts and the lights to settle down (a minute at least), then turn on the printer.

After that the printer is connected to your network, enable web services on your device, accept the firmware updates that may be provided and add your printer to your account on HPePrintCenter.

In some cases, you will need to add the printer to your computer printer / printers my file again, after you set the new manual IP address.   If you have problems printing to your printer, just use the option to add a printer, select the type of network printer and complete the Add Printer Wizard.  You won't have to reinstall any software of the printer on your computer.

F. control port/proxy problems of 

 

Note: these questions are not commonly encountered and primarily affect users in commercial contexts.

  1. ePrint and printing applications require access to establish connections to HP servers through ports 80, 443, 5223 and 5222.   Mainly in some corporate environments, network administrators can block features original communication inside of the firewall on some of these ports.  Please check with your network administrator or your Internet service provider to make sure that these ports are not blocked on your router/firewall for communication always maintained by your printer.

Important note: we do not suggest that you configure port forward on your router to open these ports for connections initiated from outside your network to your printer.  That is not necessary and could be a risk for the security of your network.

2. in some corporate environments of local network that the printer is connected to the may require a configuration proxy to access the Internet.   Check with your COMPUTER or Internet Service Provider (ISP) administrator for proxy if necessary.  Most of the ISP for the users require no configuration of the proxy for Internet access.  (Note: web HP connect printers currently do not support secure proxy servers)

To set a proxy on an Officejet all-in-one, see this document: http://support.hp.com/us-en/document/c02524629

If the previous steps have not resolved your ability to use ePrint/Print Apps, please submit a question in the support forum here, confirming that you have completed this connectivity troubleshooting and identification of the error/problem you meet.  Thank you.

I am an employee of HP.

I would start by setting a static DNS on the built-in web server (EWS). Here is a link to another post where another Photosmart was having a similar problem: http://goo.gl/0zH0x. There, it will list the steps to configure static DNS. I hope this helps.

  • What is POP, POP3 and IMAP, when I set up my email account in the HP ePrint App?

    I did as much research as I can do regarding the implementation of the HP ePrint App e-mail accounts.  If you do not see your e-mail information listed here, feel free to post below or contact your internet service company provider, by phone or e-mail, or to anyone else who might know this. I am sure there are many others that could be added, but this is a pretty comprehensive list.  I hope you find what you need to complete the setup of your e-mail applications.

    I noticed information differs from site to site, but as I've learned over time, masking the area and companies buying other companies, I just studied all the information that I could find and also if one of the names of hosts or ports does not work, then you can continue see below on this page to see if this information is the same. At that point, if you do not find what you need here, I would say that you have done all you can do before contacting appropriate for your information by email support team.

    Most of the links is active and those listed below should send you directly the pages I pulled this information since then, but only a few of them came from the real support of the sites themselves (Apple support was vague, as well as Microsoft, Macintosh and commonly used Internet services providers). Save you time by searching here first.  I hope that you will find what you need in this one-stop-shop and if you get an email that is not listed here, please report it below and I'll add it to this original document.

    Finally, as this information comes to the forum and other non-official sites, I want to add that it is a document of copy/paste/edit-for-easy-read I created in my spare time. It is a very long document, so I do is recommended to use the search and find keys to find the email that you need, but the upper part of this definition has as to what the servers, ports and are host names and the basic setup in case you need to know what are these options and their meanings.

    Here are the most common settings needed to implement most of the Clients POP3/IMAP e-mail or devices:

    The following information below can be found at http://www.swestcom.com/Support/q4.htm

    "What is POP3?

    Post Office Protocol version 3 (POP3) is a standard messaging protocol used to receive e-mail from a remote server to a local e-mail client. POP3 allows you to download e-mail messages to your local computer and read them even when you're offline. »

    "What does IMAP mean?

    The Message IMAP (Internet Access) protocol is a messaging protocol that is used to access e-mail on a remote web server from a local client. IMAP and POP3 are the two most common of messaging Internet protocols to retrieve emails. The two protocols are supported by all e-mail clients modern and web servers.

    "Main difference between IMAP and POP3:

    The POP3 protocol assumes that there is only one client connected to the mailbox. On the other hand, the IMAP protocol allows simultaneous access by multiple clients. IMAP is suitable for you if your mailbox is about to be managed by several users. »

    "What is SMTP?

    SMTP simple Mail Transfer Protocol () is the standard protocol for sending emails across the Internet. SMTP uses TCP port 25 or 2525 and sometimes you may have problems to send your messages in case your ISP has closed port 25 (How to check if port 25 is open?). To determine the SMTP server for a given domain name, the MX (Mail eXchange) should have more information."

    "When you set up:

    • POP - choose that POP-UP and the port entering the default server to 110
    • IMAP - choose IMAP and the port entering the server by default to 143
    • All other parameters are the same.
    • Username = [email protected]
    • Password = the password you set up when you set up your mailbox
    • = Incoming mail server mail.yourdomain.com
    • = Mail server outgoingsmtp.yourdomain.com
      • Outgoing requires the authentication of the server (typically found in the settings or advanced options)
      • Do NOT select "Log on using Secure Password Authentication".
      • Use the same username and password as incoming or select "use same settings as incoming.
      • Outgoing server port= 2525 or 587
        • It is subject to change according to individual preferences of your ISP.

    Note - Replace with your domain name for "yourdomain.com" and replace the first part of your e-mail address for "user".

    Email ports
    For networks, a port means endpoint to a logical connection. The port number identifies what type of port it is. Here's the e-mail ports by default for:

    • POP3 - port 110
    • IMAP - port 143
    • SMTP - port 25
    • HTTP - port 80
    • (SSMTP) - port 465 secure SMTP Protocol
    • Secure IMAP (SSL IMAP4) - port 585
    • IMAP4 over SSL (IMAPS) - port 993
    • Secure POP3 (POP) SSL - port 995.

    It is just to recap, a series of ports for people who need this information when you configure the HP ePrint app so that they could see their email from the app, I've collected over time.  I am sure that other applications also need this information.  Although long, I couldn't find a more complete place to retrieve this information.  Feel free to post additional information, faulty information or other associates subject below that it is simply a collection of data and it would be virtually impossible to test all of them. Thank you!

  • ePrint app and printing by e-mail

    Just installed a Laserjet M451dn, registered with hpeprint.com, and if I print via e-mail to the printer, it works fine.

    Have also just installed and activated the ePrint App on my iPhone 6, but I am currentl 20 miles hence my printer is. The app does not seem to search for wifi connected printers, but the FAQ says I can print from "any where in the world". If I open a web page in the application (for example), click on the "optimized" button - how do I do so that print from the App? He said "no printer found. I understand that I can send mail from the phone, but it's outside the ePrint App and I expect to be able to print the optimized page, I can see the app.

  • How to delete the files from my HP ePrint app after download / print?

    Can someone tell me how to delete the files from my HP ePrint app after that I downloaded and printed. Thank you

    jmsandkds,

    I apologize for the confusion. Options you speak of "photos, web and file" are located on the phone somewhere, lets say you click files. When you click on files, it will search the phone for available files that are able to print the ePrint app. To the extent where they are on the phone, you will need to search for them via the search screen, connection to the computer, or some files are program specific and only available in this program to be read, edited, or deleted.

    I hope this helps.

    Hello

    I try to print using the HP eprint on my Android mobile application. I am able to print using the WiFi on my phone but when on the go, the app will not find the printer. The eprint service works correctly since I can print when sending an email to my address of email eprint even when I travel but the application won't work when the printer of the Internet access. The printer is connected to a cable modem, wireless. Is there a way to print through the Internet using the HP ePrint app?

    Thanks in advance

    Well after I asked a few friends with iPhones and Android devices to print over the Internet using the application, I noticed that everyone could.

    So, initially, I reset the printer to the factory setting and reconfigured it. It has resolved all the issues I've had both with built in the application to manage as well as my phone. Now I can normally use the HP ePrint app on the internet and printing.

    As a side note, I downloaded an update of the firmware to the printer and most probably caused problems, but, as says the resolved all factory reset.

    Thank you.

    Hey @Cpedron,

    Welcome to the Forums of HP Support! I hope you enjoy your stay here.

    I understand that you have an old printer that makes its appearance in the HP ePrint app that you no longer own. While I can't help you with the removal of the printer, I can help you prevent the printer to appear. To do:

    1. Reset the App data.
    2. Uninstall the HP ePrint app.
    3. Download the app again.
    4. During installation to validate the HP ePrint app for using a different e-mail address than the one you previously used.

    This should avoid the printer appear. Using a different e-mail to validate will have no effect on the operation of the program otherwise.

    Please let me know if this resolves your problems or if you have any other questions. If not, have a great day!

  • HP eprint app does not detect photos on iPad

    Hello

    I have the HP eprint app on my ipad. I went to print a photo that I took on the ipad today, however, when I went for this app asked if he could access the camera or something like that. I wanted to press ok, however, I clicked do not allow. So when I went to print the image using the application and pressing the button photo in it no pictures not found. I deleted the app and reinstalled two times, but still no pictures are presented when I use the app to print a photo. Can you please help. I can print from the web always.

    Thanks for any help!

    Hi beckys2000,

    I see that you have a printer additional use you want to control, unfortunately, there is nothing that I can locate in the printers setting you will discreetly or other wise, place the printer on lock down.

    You can however, if you have your dear credit card, order ink directly from your HP ePrint App on your iPad. Tap the SureSupply icon at the bottom of the home page, follow the first installation and choose the best deal on ink.

    I know that this is not the perfect answer, but at least once inks arrive, you get your printer to your self again.

  • ePrint App: Safari extension

    It is not a question that can be resolved, but I wonder why the HP ePrint app on my iOS device is not configured to be an extension of action of Safari? I think that this would significantly improve the application so that employers do not need to search for a site once again on the app when they want to print something. Instead, people could just rely on the extension of the action and open the Web on the HP application. Just an idea to consider for the next update!

    Thanks for reading

    Hi CN727,

    Thanks for your suggestion.  I'll forward it to appropriate the ePrint group team.
