Can't get HP Officejet Pro L7780 Online

I replaced my old HP computer that uses Windows XP, in my home network with a new computer integrated custom system running Windows 7.  The documents will not print because the computer thinks it is 'offline', and diagnosis tell me to turn it on. He obviously knows that the printer is there because it is able to recognize all the information of the printer (name, model, S/N), and I can access the printer EWS. I downloaded new drivers for Windows 7, although as soon as I plugged the printer the found computer and installed the drivers. Also, I can not connect to the computer to use the digital archiving functionality, which I use regularly. Any suggestions?


I solved this problem by going to the site of HP download and installation of the entire Center of HP solutions for my printer and the current operating system. I then used the solution Center program to install the printer and viola, it works. Just after I installed the printer drivers and the computer recognize the printer is apparently not sufficient to establish communication.

  • You are using windows 7, how can I get my Officejet Pro K8600 print on paper 13 x 19?

    I bought a laptop with Windows 7. Now I can't get my Officejet Pro K8600 to print correctly on paper 13 x 19. It prints on paper 13 x 19, but everything is 8.5 x 11 in size. I click on print, click Properties, change the Super B 13 x 19 paper, press ok, watch box paper 13 x 19 with images by filling out the document, I click ok to print and it prints the image 8.5 x 11 in size on paper 13 x 19 rather than fill the paper 13 x 19. I did not have this problem (and still haven't) with my old laptop with XP. It is the operating system or is it a bad setting in the properties? I tried to compare the property settings in both computers, but I can't find any differences. I don't think it's the driver... Please help!

    Hello HW,.

    Try this: go to devices and printers and right click on the of K8600 Officejet Pro and click on printer properties. Go to the Advanced tab and click on the button called Print Processor. Select Winprint. Try another print and see if it works now. If you still see the same question to see if there is an option of scaling in the print dialog in the application you are printing from.




    The error message itself will remain but will continue to print. This message will remain until the cartridge is replaced. Substitution is the printer printing always regardless of the error message on the display screen.

  • HP Officejet Pro L7780: HP Officejet Pro L7780 Solution Center does not work even though I can print

  • OfficeJet Pro L7780 can't scan to PDF

    I have an OfficeJet Pro L7780 HP sent me after giving up on a 7310xi of fixation. I installed the software a message received a 'fatal error' on the error code 2203. He went ahead and installed OK - I thought. I even went to and searched this error code. From what I gathered, it had something to do with registration it... so I do not download their fix. Once installation is complete, I went in the scanning settings, because I scan a little bit. I discovered that the PDF file option did not appear in document scanning settings. Only BMP, JPG, TIF, PNG, PCX and FPX are listed, which are, in effect, the types of files that do not exist in the image scanning settings. It's as if the software loaded the same types of files in the settings of the document scanning and photography.

    I wonder now if the fatal error message actually related to this problem.

    Any advice... below to uninstall the entire package and start over again?

    Thank you...

    Thanks for the reply. Yes, I have installed Adobe Acrobat.

    I finally abandoned and went on the website to the address support HP Contact online us, and they have solved my problem. They put me installation disk, click the add additional software option and install the OCR software. Once I did that, the PDF option, along with others, appeared in the output file to scan a Document.

    Go figure.

    Thanks again.

  • All-in-one Officejet Pro L7780: driver HP Officejet Pro L7780 will not install with Windows 10

    Recently, my HP Officejet Pro L7780 stopped printing. I uninstalled the driver and then reinstalled the driver from the HP website. Every time, when installing, I get a message that "bing bar does not work on this version of Windows. Once the installation is complete, the test page is fine but I can't print from one of the applications (e.g., WORD, Adobe Acrobat, etc.), getting an "Error printing" message, rather than each time.

    I use Windows 10. The printer was working fine since I've upgraded to Windows 10 until recently.

    I've uninstalled and reinstalled the driver several times as suggested on the HP website. Any suggestions on how to solve this problem.

    Thank you.

    Hello @AMNYC2015and welcome to the Forums of HP, I hope you enjoy your experience!

    I see that you are having errors in the print driver. I would like to help!

    I recommend to remove the cartridges ink and starting by a power reset.  Unplug the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug back in the printer. Make sure that you connect the printer directly to a wall outlet. Make sure to bypass any surge protector or power bar.

    I also recommend running the HP Print and Scan doctor.

    Good luck and please let me know the results of your troubleshooting operations. If this solves the problem, click on accept the Solution below, as well as others to find the answer.

    Basically what happens is that I can open the Solution Center, but when I try to open either Photo or Document scan I get a gray pop saying "The HP Imaging Device was not Found" it tells you so what do I do, but all of these steps have failed.

    I noticed something is in the Device Manager, devices for imaging and printers, Officejet Pro L7700 under events, I also have this message.

  • Solution Center does not work under Windows 7 with Officejet Pro L7780

    Downloaded the latest version of the software for Windows 7 and the first issue was when you try to do an installation complete you get a fatal error at the 96 percent mark when she did the configuration. I looked on the web and found a lot of posts on the same problem. Then, I just uninstalled and made a gradual installation.

    Main printer DRIVER installed first. Then did the functions of imaging followed by the solution Center device.

    Installed everything, but when you run the solution center it says it can't open because incomplete installation.

    The printer works from Windows 7.

    I have an XP machine and Solution Center working on it.

    Any suggestions anyone.

    This thread has resolved the problem installing the software that supports the HP Officejet Pro l7780 for use on Windows 7.

    The event viewer showed mistakes that network location for %APPDATA%\protector.exe is not found.

    Even if I couldn't run the original installation of solutioncenter.msi to work without errors in the log file, without making any changes, which has not completely solved the problem.

    Since solutioncenter, initially did not work, I decided to run solutioncenter.msi manually and look at the log file. See errors in the log file we made changes to the database with Orca solutioncenter.msi. It took us on a long road that does not initially sense that HP would put something out there that produced errors in the msi log file.

    I don't know how the setup.exe uses solutioncenter.msi?

    The changes that doesn't seem it to matter when you run the setup.exe file that is provided in the download.

    If I used the modified solutioncenter.msi or version orginal of it as downloaded from HP running setup.exe site had no importance regarding obtaining solutioncenter work in windows 7, canceled only changes in the solutioncenter log file errors.

    I had to make the following changes to the environment variables to get the full package to work, but what is strange is that I could replace the changeed solutioncenter.msi or the original solutioncenter.msi and run setup.exe, with the following environment changes didn't matter. The solution Center has worked in Windows 7 using one of the solutioncenter.exe and setup.exe.

    Apparently, setup.exe does not use the MSI directely. I think that HP responses suggested that in a previous thread.

    Add these entries (click new...) for the owner user variables and System variables:

    In the name box: APPDATA

    In the value box: %USERPROFILE%\AppData\Roaming


    Run setup.exe and event viewer does not display % APPDATA % Scriptures and all work.


    Thanks for all help on this.

  • OfficeJet Pro L7780: Officejet Pro L7780 missing of the vertical lines on text & photos

    Everything that I try to print has lack of vertical lines, text or photos. Happens if I print from my computer or if I try to copy a page directly to the printer. I went through the troubleshooting page full... the ink is all well heads, all good impression. Whenever I try to run a printer align it does not end the page. Whenever I have nothing he's trying to align printer print when its done & still cannot print the entire page. Gives me an error and says to check my documataion. I checked the book with my printer & there is nothing in this whole problem.

    Help, please!

    Hi @LockGal,

    Welcome to the Forums of HP Support!

    I see that you are having problems with your HP Officejet Pro L7780 printer aligning and printing vertical lines. I'd be happy to help you and don't forget to come back to this thread and check "Accept as Solution", if I have successfully helped solve you the problem. If you want to say 'Thank you' to my effort to help, click on the "thumbs up" to give me a Kudos.

    I understand the frustration that this must be for you. Looks like there are two separate issues. When the printer clean print heads and not properly align itself, this indicates that there is a problem with the cartridge, the print head or the line break. For vertical lines, it is usually independent for cartridges and print heads (not being is not a print quality problem). The paper type and print settings might be the problem.

    To help determine the cause have you used this document: troubleshoot print quality HP Officejet Pro L7500, L7600, and L7700 all-in-One Printer Series?

    Use the document in the order will help you determine if the print heads need to be replaced. If so, please contact HP.

    Please confirm that the vertical or horizontal lines?

    NOTE: are not replace the cartridges and printheads for vertical streaks in a print. Instead, check the paper as directed earlier in this document, or search for a document that addresses this issue. Vertical streaks on copies can often be fixed by cleaning the scanner glass.

  • SNMP eat upward of bandwidth on my (HP officejet pro L7780) ethernet

    Hi all, I am running Win 7 (64-bit) on my server, ethernet to a router from linksys gateway 3000. Attached to the same router the Ethernet is a HP OfficeJet Pro L7780 printer. I have a printer HP Deskjet 6988 ethernet attached to a hub (with a link to my linksys gigabit). There are many other devices Wi-wired and connected to this network. The problem I see is the following: I use a client of Wireshark network sniffer on my server. When you run a trace on the ethernet on the Linksys router, I see a large number of SNMP get requests and get responses. These are still ongoing between my server and the HP Officejet 7780 (never in/from) the HP Deskjet 6988.  This segment of my network is flooded with such things SNMP. You wish to know which packages are and how can I cut most of this. Surely, there must be something in the printer software HP on my server that can be tweaked to eliminate most (if not all) of this SNMP traffic...   Everyone?

    You may also lose the ability to check your computer ink levels and some other utilities.  You may re-enable the services when you need to scan.  Stops the service and see what happens!  You can always enable it back.

  • OfficeJet pro l7780 wireless works do not since the firmware update

    Is there a restore utility for an update of the firmware?  I have updated the firmware on my Officejet pro L7780 AIO hoping to solve a problem of scanning; However wireless capability has since stopped working.  I tried a static ip address - disconnect the power supply, check that the SSID and password, etc..

    The wireless network Test report page. RADIO ON IS PASS, RADIO WORK = FAIL, PASS = NOT CONNECTED ETHERNET CABLE.

    The previous Firmware before I upgraded was: R0040xxNxeN0; The version of the installed software package now is: R2011NxNxeN0.

    The printer works with a straight ethernet cable to my router Netgear Rangemax Wireless model WPN824v2. However, it seems that I can only access the printer from my laptop through my desktop computer (which is networked via ethernet to the router) wireless - and the desktop computer must be powered.

    (PS; Update does not solve problem of scanning)

    Hello world

    I increased my support to management and after having crossed some tests additional etc, it was determined that my problem is, indeed, a hardware failure.  HP offered me a replacement refurb for $245 includes taxes & shipping in both directions, as I mentioned in my last thread, they don't sell parts for this model, that's why I decided the lesser of two evils... spend more money & buy new or take the offer... I take the offer.

    Thanks for your help.


  • HP Officejet Pro L7780 - network letter nightmare!


    I'm hopin that someone can help with a problem I have with my HP Officejet Pro L7780:

    The printer is connected to my wireless network and all is fine with that. The problem lies in the letter from the network that it sets itself on my PC (Windows 7 Ultimate) for the card reader on the printer. It uses the same letter as a virtual cd-rom on my PC drive - and I would like the letter use printer - and not the cd-rom drive, as I have my PC configuration in a way where are grouped different types of readers. Is it possible (possibly via the Windows registry) that would allow me to change the drive letter of the network (as it seems to automatically assign them one) and keep it with this new letter rather that interfere with the cd-rom drive and denying access to him every time that Windows 7 starts?

    Or otherwise disabling the function of card reader on the printer I do not use it?

    Thanks to anyone who can solve this - it's driving me crazy!

    I finally found a solution to this problem that works for me.

    I too have an HP printer that was mapping its card slots memory on drive Z: every time I start my Windows 7 computer.

    To change the map to another letter in order to release the letter Z:, I put a memory card in the printer memory card slots. I then unplugged the drive Z: printers mapping (right-click the Z: drive in Windows Explorer and choose the option to logout).

    I then used the "Map network drive" option on the toolbar of Windows Explorer to map the slot for memory card printer to a different drive letter. [You must know the address (or network name) of the printer to do this: name or network \\[printer address] \memory_card (e.g.: \\\memory_card). This address goes in the 'Folder' dialog to map text box. Make sure that the option "Reconnect at logon" is checked. And make sure you only select a new drive letter that is not necessary for any other thing later. Then click "Finish."

    After doing this, the printer has continued to use the new drive letter to start instead of Z:, leaving Z: free for other applications.

    I do not think that works above if there is no memory card in one of the printer memory card slots.
