HP Photosmart C4780

My operating system is windows 7, home premimum 64 bit.  I have a HP laserjet P1606dn printer installed. I have also installed a HP photosmart C4780 printer several times. After a brief period of time my computer removes this printer completly. I think I have the latest drivers. Any help will be appreciated.

I have 3 different printers installed, but only 1 printer can be the default printer. From that premise, I can select a different printer as needed from within the menu bar of the program I am using, at that time.
Your problem is unique, as computers do not think as an intelligent entity. How could it remove an  installed program on it's own volution>?

  • Cannot wirelessly connect printer- HP Photosmart C4780

    Hello everyone! I have scoured the internet and these forum pages for a solution, but could not find any. Anyways, I have a HP Photosmart C4780 and am unable to wirelessly print. My printer will not connect to the internet nor does it show a local network for my computer to print to. When I try to print off a Network Configuration Page, it will not let me. I click the "Ok" on the printer when that option is highlighted, however it takes my back to the wireless menu. I have an AT&T router that I believe does not have a WPS. I also have the latest software downloaded on my 2015 macbook pro. To make things more complicated, I do not have the set up wizard disk, and when I try to download the corresponding software to get the "HP Folder" on my computer, it goes through the installation process but does not show the folder once it is finished. Please help me!

    Hi , I see you have been looking for a way to reconnect your c4780 wirelessly with your Mac 10.10, I have actually helped with this before. Normally, it's an easy 3 step process to reconnect the printer but because you have Mac OS X 10.10 Yosemite which uses the driver from Apple, there is no software package from HP to configure the wireless. 
     So here's how you can do this;  Step 1:  Make sure your computer is connected to the correct network. Confirm your settings for your home network; HP Printers - Find Your Wireless WEP, WPA, WPA2 Password (Mac) Step 2:  Restore the Network Defaults on the printer so it's not holding onto any old information.* To do this you should be able to touch on Setup [Scan] front of the printer then choose Network and then Restore Network Defaults Note: If your wireless radio is not working correctly, let me know and I will send you a different reset in a private message.  Step 3:  This would normally be to use a USB cable and your printer software to configure the printer back onto the network but you will need to follow the directions from this similar post, copied here for you below; After you Restore Network Defaults, the radio will turn off (the blue LED will go out.) You may need to press the wireless button again to Enable Wireless (light should be flashing.) Put the computer on the printers network (temporary)1. Click on the Airport symbol on the top left side of the Mac screen
    2. Choose the network that look relative to the printer (might say HP setup or some variation of your printer name) - it may take a few minutes for it to appear Print the wireless network test - wait a few minutes to ensure the and computer have established an adhoc connection otherwise the report will not have an IP addressPress the Scan button (it also the Wireless menu button)Select Wireless SettingsNavigate to Wireless Test and select.The Wireless Network Test prints, look for and note the IP address. Open an Internet browser (Safari) and enter the IP address into the URL (address bar). Click on the network tab, on the left click on wireless or 802.11. At this point we are looking fore "start wizard" should be on the right hand side. Now just follow the on-screen prompts to configure your printer to the network.    Once we have successful configured the printer for your network you can put your computer back on your own network. Now you can add the printer to the System Preferences and print. (If you are unsure of how to do this see; Add or remove a printer.   Please let me know if these steps resolved your issue, or if there is anything else I can do to help.  I look forward to hearing from you!   Thanks, 

  • HP ePrint iOS app no longer finds Photosmart C4780 after app update

    I have an HP Photosmart C4780 connected through WiFi to my network but sadly it's not supported by AirPrint on iDevices.
    So, I was using HP ePrint Home & Biz iOS app (version 4.1) which was very useful for me as it found the printer and allowed me to print from my iPad/iPhone. 
    Today I updated the app on my iPhone to version 5 (now simply named "HP ePrint" on the App Store) and after the update, the new version doesn't find my Photosmart C4780 anymore. I did the Activation thing on the iPhone, as it was requested to refresh the list of printer on my network in the All tab, but after Refresh no printer is found.
    Still I have the old 4.1 on my iPad (and hopefully in my iTunes library) and the printer is located, I assume, through mDSN as it shows the name specified for this setting.
    So, question is: Did you dropped support for Photosmart C4780 on 5.0 release of HP ePrint iOS app? If so, why did't you informed this appropriately on the app update text description in the App Store? A message like "some printers may not be supported anymore" would have been helpul.
    If HP ePrint should find Photosmart C4700 series printers and this is an issue, how should we proceed from here?
    Thanks.

    WilliamBPS, 
    I was not informed that support was removed from the app for certain printers. It may have been lost in the transition to the new updated app. I will deffinitly pass this information along as it is very important that the app supports as many printers as it can. I'll go ahead and take note of your printer model. If I find anything out about this, I'll try to give you an update in this thread.

  • WiFi connection problem from HP Photosmart C4780 to MacBook Pro

    I have an HP Photosmart C4780 that will not connection to my MacBook Pro.  I am operating on the Mac OS X 10.6.8.  It was working just fine when I was using my Apple Airport to project the WiFi in my house, but I recently bought a Apple Time Machine to back up my system and have a main networok and guest network for the house.  When I switched to the new device, I am now unable to get my printer to reconnect via WiFi.  I have downloaded all of the recommended software from the HP site.
    When I click on set up wireless connect, it starts the first step to find the device and then I wait and wait.  It just sits and spins and never finds the device.  Yes I have it plugged in and turned on.  I did not have any problems with this prior to switch the router for the WiFi so I am guessing it has to do with that, but I am lost on what to do.  Please Help  

    Welcome to the HP Forums FlyGirl_1350,
    I see by your post that you now have the Apple Time Machine and aren't able to setup the printer again on the network.
    I can help you with this issue.
    Follow these steps to restore your product's network default settings. This will clear out the old router encryption.
    Touch the ATM button () next to Wireless / Scan.
    Touch the ATM button () next to Wireless Menu.
    Touch the ATM button () next to Wireless Settings.
    Use the up and down ATM buttons () to select Restore Network Defaults, and then press OK.
    Touch the ATM button () next to Yes to confirm your selection.
    Make sure the computer is connected to the Main Network Name and not the Guest Network name.
    Vice Versa. Sometimes the printer won't pick up the Guest Network to configure the wireless.
    Run the setup again.
    This document provides steps for setting up the printer on the network also.
    Installing the Printer Software for a Wireless Network Connection (Using an Access Point).
    If you are still having issues then power cycle all the devices in this order, power cycle the router, wait till it is back up again, turn the computer off and on again, turn the printer off and disconnect the power cable for 30 seconds, then reconnect it again.
    If there is anything else that I can help you with just let me know.
    Have a nice day!
    Thank You.

  • Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX 10.8.2 Mountain Lion.

    Hi!
    Didn't know exactly where to direct this question in the Apple Community so I chose Airport.  To everyone, thanks in advance.
    I’m really desperate. I’m a big Apple fan.  I have two Apple MacBook Pro laptops with Mountain Lion software.  I also have an Apple Airport Extreme.  My HP Photosmart C4780 printer was also purchased from Apple.  Anyway, my Internet service is AT&T.  AT&T just upgraded my service with a new modem/router (AT&T U-Verse).  Prior to the conversion, my wireless printer connection was working perfectly.
    Now can’t print wirelessly. For your information, everything is connected via Wi-Fi. The AT&T technician stated that I no longer needed my Apple Airport Extreme, so it was removed.  Naturally, after the tech leaves, we find out the HP printer wirelessly no longer works.  Thinking that removing Airport Extreme may have been the problem, I reconnected it to the AT&T modem/router, however no change.
    This appears to be an HP printer problem.  I went to HP community support with the information below but I have received no solutions outside of buying a new printer.
    “Ran the HP wireless network test report and it states that HP printer can’t find wireless router and to verify that the HP printer network name (SSID) matches the wireless router network name (SSID) exactly.  The Diagnostic Summary in brief:  Wireless On & Working & Security – Pass; Network Name (SSID) Found – Fail. Nothing else under diagnostic summary ran.  Under Configuration Summary:  It shows old SSID name and Mac Hardware Address but no IP Address.
    Next ran the Network Configuration Page and everything is enabled except the 802.11 Wireless.  It shows status – disconnected.  Under general information it states the following: Network status  - Offline; Active Connection Type - None; URL(s) for Embedded Web Server – http://0.0.0.0.”
    To be straightforward, I’m no computer tech so I don’t know what this means or where to find.  The AT&T tech provided me the new SSID Name and a wireless key number but that’s it. Also I uninstalled and reinstalled via USB. The HP message states can’t find router. At this point, I’ve tried everything to reconfigure without success. If I need to make these changes via Airport Extreme Utility 6.0 not easy to find not that I know what I’m doing.
    Most importantly if I ever get wireless working again, do I still need Airport Extreme connection or is the AT&T U-Verse modem/router sufficient?
    Any direction or help is greatly appreciated.  Thank you for listening.

    Thank you for your prompt response.  I'll be honest I'm a retiree and a newbie to all of this stuff. I don't even know how to do a thread. (Embarassing) This is my first ever contact with the Apple Community so I'm slowly trying to figure this out as well. 
    As to your thread request, I'm assuming you want to read my post with HP.  Not knowing how to thread, I've copied it below.

    Re: Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX  10.8.2 Mountain Lion.              
    I finally figured it out! (Sorry that I'm replying to my own posts btw, but I want to post the solution for anybody else with the SigmaplusEOL1 problem). If you have the SigmaplusEOL1 as your SSID when you  print the "Wireless Network Test Report", you do NOT need to return it (I know that's hassle for people).  To fix the problem, follow these steps.
    1) Unplug your printer.
    2) Go to your router's IP address (like 192.168.1.1 or whatever it is for your router).
    3) Change the SSID of your wirelss network to "SigmaplusEOL1".
    4) For the Security option for your wireless network select none (so that a password is not required to access your wireless network).
    5) Power your printer back on and reprint "Wireless Network Test Repor". It should say "No problem found..."
    6) The report should also have a the IP Address of the printer (under Configuration Summary at the bottom). Type that IP Address in your browser to get to the printer's settings page.
    7) Click the "Network" Tab at the top.
    8) Under the "Connections" header in the left pane, click "Wireless (802.11).
    9) Click "Start Wizard" at the bottom right.
    10) In the wizard, change the SSID and encryption (wep or wpsk) password to whatever you want your wireless network to be. So probably whatever it started out as before you changed the SSID to SigmaplusEOL1
    11) Click "Finish" at the end. The page will probably try to keep loading but it won't because you changed the network settings of the printer. Just ignore that
    12) Go back to your router's IP address and change the SSID and encryption password to whatever you changed the printer's SSID and password to.
    13). Reprint the Wireless Network Test Report. It should say the SSID is the same as your wireless, and everything is good.
    That's it. You should be good to go now.
    Re: Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX  10.8.2 Mountain Lion.              
    Thank you for your prompt response.  This has been a totally frustrating experience.  I’ve spent at least 8 hours trying to fix this.  My HP problems and your initial steps were identical to mine.  I am by no means a tech person and my computer tech knowledge is minimal.  However I followed your steps to the best of my ability.
    I did get the SigmaplusEOL1 message.  I was able to get to Step 6 where the wireless network test report now reads – “HP printer settings do not match your wireless router settings.”  So I guess this is a step in the right direction.  However unfortunately the Configuration summary message for the IP Address reads – “Not Applicable”.  (Note: changing SigmaplusEOL1 to network name knocked out my Internet access.  Had to switch back to regular network name to regain access.)
    I’m at a loss as to what to do next.   Without the IP Address is it possible to move forward?  As I stated earlier, I’m not a tech person.  As to your steps 7, 8 and 9, I can’t find them on my computer or maybe I’m looking in the wrong places.  In System Preferences - Network, I have none of these steps.  If you’re referring to Airport Utility, with the changes in Mountain Lion, these steps are no longer there. If you’re talking about Safari, Firefox or HP, now I’m really lost.
    Finally, I don’t know if you can answer this or not.  If I ever get wireless working, do I still need Airport Extreme or is the AT&T U-Verse modem/router sufficient?
    Again thank you for your time and patience.
    Re: Can't connect wirelessly HP Photosmart C4780 to MacBook Pro OSX  10.8.2 Mountain Lion.                  
    Unfortunately I am unable to offer any further advice as I only followed the instructions listed on the other page.
    Finally, as to having WEP enabled, I don't know.  Don't even know where to look.  The best that I could determine is that my security is WPA/WPA2 Personal.
    I'm truly sorry about all of this.  Thank you for your time and patience.  After reading all of this and you change your mind, I would understand.

  • Photosmart C4780 install fails at "system cannot find specified file"

    My problem started simply with the printer, an HP Photosmart C4780 which has always had a wireless connection and would not print.  At first, the network connection checked out fine from the printer control panel.  I ran a Microsoft printer troubleshooter, which found a block in the print queue, and cleared it.  The first test page would not print, but the "inner test page" did print.  I didn't understand whatever that meant, so I looked for help from the HP site.
    I ran the HP Print and Scan Doctor, and it suggested I reinstall the driver.  I downloaded and saved the current one from HP (PS_AIO_06_C4700_USW_Full_Win_enu_140_175.exe) and then uninstalled the existing driver.  When I attempted to install the new one, a window popped up saying, "The system cannot find the specified file," with only one box to click which said simply "OK".  The installation went through to "review installation options", after which came “checking updates, downloading updates, installing updates” and then it was while “checking system” that the “cannot find the file” window popped up, and when I clicked “OK”, the installation window as well as the error message box, just disappeared.  What I assume was the file path was in the frame of the window, but the whole thing didn't fit so it didn't show the end.  What I could read was “C:\Users\ … \Local\Temp\7zS588E\Setup\.\Setup\hpzpnp40 …
    I found one topic on the same problem for the same model printer in the forum, which offered this fix:
    You will need to first complete a level 3 uninstall of the software. I have included the steps below for this.
    1. Press the Windows key, and the letter R
    2. Type %temp%, and click OK
    3. Open the 7z folder (most recent one if there are multiples)
    4. Open the util folder
    5. Open the ccc folder
    6. Double click on the Uninstall_L3
    Once the Uninstall_L3 has completed, please delete all items listed in the temp folder. Note, you will  not be able to to delete all items, please skip the ones that you cannot. Next please empty the trash, and perform a clean boot. I have included the document 'How to perform a clean boot in Windows'. If your computer does not request it, please restart your computer.
    Once your computer is back up, you will need to reinstall the printers software. You can either do this by using the Installation CD, or downloading the software.
    I did what was suggested, until it got to the point where it said it did not recommend removing any further items if I intended on using the HP Officejet printer (yes I have a second HP printer attached to the network) anytime in the future.  Not really understanding how this all works, I decided to stop what I was doing, so unfortunately it did not solve my problem.
    Do I need to uninstall both HP printers before I can reinstall one?  And if I do that, is there any reason I would not be able to reinstall both printers?  Sounds like I'm asking for trouble.  Bottom line... I still cannot install the driver.
    I have tried to install both the full and basic versions of the driver and always get the same result.
    I have an HP Pavilion dv6-3100t notebook, running Windows 7 Home Premium, version 6.1.7601 service pack 1, 64 bit.  I haven't installed any new hardware or software.  This printer has always had a wireless connection.  The router I use is a Netgear 54 Mbps WGR614 v6 (supplied by my cable company), and the network includes not only my notebook and the Photosmart printer, but also an ASUS desktop, another HP printer, an Officejet 6300 series (used only for printing graphics and photos with a wired connection to the router), and a Vizio smart-TV.  I use Norton 360 Premier Edition and disabled the anti-virus auto-protect when I downloaded and attempted to install the driver.
    Please help!  And thanks in advance for your time and attention.

    Hi wakey-wakey,

  • Photosmart C4780 cannot connect to wireless network

    My Photosmart C4780 was working just fine, wirelessly, and now I cannot print unless I connect it to my laptop or desktop via the usb cord.  I am running Mac OSX 10.9 with the Mavricks downloaded on both computers.  I was able to print from my Mac Mini, iPhone, iPad and MacBook Air all without issue but now my Wirless Network Test Report says I fail "Network Name (SSID) Found".  The HP Network Configuration Page says my Netowrk Status is Offline and my Active Connection Type is None but I can see my network listed under Number of 802.11 networks discovered.  I believe I just need to connect or reconnect the printer to the network but I can't find how to do that anywhere on the help site.  Can anyone tell me how to connect my printer to my network now?  When I first installed it onto the network I didn't have OSX 10.9 with Mavricks so the installation CD worked just fine but not it won't work either.  One more thing, when I try using the screen on the printer and go through the WIFI Protected Setup both Push Button and PIN fail.  HELP PLEASE.....

  • Wirelessly Printing from a Macbook Pro to an HP Photosmart C4780

    Hi everyone,
    I've recently just purchased a Macbook Pro and an HP Photosmart C4780 printer. I was told in the Apple store that I could print documents and photos from anywhere in the house without having to plug my laptop into the printer via USB. I have plugged into the printer directly via USB and printed successfully, though I am still experiencing difficulties while trying to set this printer up to print wirelessly.
    Can anybody guide my through step by step to get this working? Any help would be very much appreciated.
    To clarify, I don't have an Apple router (such as Airport Extreme or anything like that).
    Thank you!

    You could start by resetting your printing system and then see if the computer sees the printer. http://docs.info.apple.com/article.html?path=Mac/10.6/en/14001.html
    Is your wireless network protected by a password? Does it have a name?
    I have a wireless HP AIO that I connect thru my wireless router. In other words the wireless router is the hub for the printer so the three notebooks and iTouch can print to it from anywhere in the area.

    Your PC can not communicate with your printer at address 192.168.1.127. Check all cable connections. Check that the printer, PC and router are powered on and connected to the network."
    I have tried turning my firewall software off and that didn't work. All cables are connected and everything is powered on.

    Thanks for your quick reply, PrintDoc! Just a few minutes ago I tried unplugging my router and plugging it back in and "Wallah!" everything connected! It's working perfectly now!

  • Cannot connect Photosmart C4780 to wireless network

    Hi.
    I have a HP Photosmart C4780 printer that I'm trying to connect to our wireless network, from my Mac (OS X 10.8.4)
    I am trying to install the printer on my MacBook using the CD provided with the printer.  The software installs, and then I get stuck at the setup. I get the message "No Wireless Network Discovered". I check the box saying " type in our network name, and get the message "Device Not Connected: To configure the network settings of the selected device, please connect it temporarily via USB. The device can be disconnected from the USB once the network settings are transferred."  I plug the USB cable into my Mac, hit "OK", then "Continue".
    Now the message I get is: "Network Unavailable: The selected Wi-Fi Network "xxx" is not within the reach of the device." (Note: the device is about a foot away from the router).  Hitting "Retry" yeilds the same error message - and I'm stuck.  
    The wireless function on the printer is on. I restored the network default settings on the printer. The router is a D-Link DIR-826L Wireless N600 Dual Band Gigabit Cloud Router.  The router is new to us - we had no issues with our old D-Link router (but it died so had to be replaced). 
    Any help would be appreciated!

    cmd1979,
    In order to get this installed wirelessly you will need three things
    1.) Windows OS system
    2.)USB cord
    3.) Full feature software from the HP website
    http://h10025.www1.hp.com/ewfrf/wc/softwareCategor​y?cc=us&dlc=en&lang=en&lc=en&product=3794615&
    You can install the software on the windows system and install it USB. Then you will be able to convert the USB to wireless through the HP software. The printer will then be on the network. On the mac you will go to Settings->Print and scan->Add printer->Select your printer from the list->Choose add.
    Let me know how this works for you.

  • No longer able to use the scan function on Photosmart c4780

    Previously when I opened my HP Photosmart C4780 Printer Scanner I would get a dialogue box which allowed me to choose whether to print or scan. This dialogue box no longer starts and I no longer get the option to select scan and can only choose to print.  I have been around the circuit of Print and Scan and Doctor and have downloaded and reinstalled the appropriate software several times all to no avail.  I can no longer find the software CD that came with the device. What do I have to do to be able to access the dialogue box which gave the opportunity to choose scan and specify the actions required?
    Furthermore using Windows Fax and Scan will not work either, I simply get the message “Could not complete scan”.
    The scanner does work as I can use the copy function perfectly well.

    Download the software and choose to save as, save to desktop > HP Photosmart C4700 All-in-One Printer series Full Feature Software and Driver
    After the software downloads and extracts, open the temp folder again, use the instructions from step 1.
    Look for, and open the folder starting with 7z (Example: 7zS2356)
    Open folder Util
    Open folder CCC
    If you have an HP computer run the L3uninstall.exe. If you have anon-HP computer run the L4uninstall.exe
