Wireless connection HP Photosmart C4780

My HP Photosmart C4780 won't connect to our local wifi network. It was connecting before I did a system reinstall, but now I can't get it to connect and I can't find any connection wizards or settings that allow me to choose a wifi network for it to connect to. 
I have it connected to an iMac on MacOS 10.10 via USB. I can print, because the MacOS loads drivers when i add the printer, but when I try to use the original HP drivers and setup wizards, they crash and won't run on my OS. 
Please help. This is super frustrating!

Hey @LaneAllison, 
Welcome to the HP Support Forum.  I understand you're unable to connect your HP Photosmart C4780 All-in-One Printer to your wireless network.  I would like to help.  
Currently, there is no HP printer driver made for Mac OS X 10.10 Yosemite that's compatible with your printer.  If the printer was already connected to wireless, you could click here to complete the setup by way of an 'Apple Software Update.'    
Since you're effectively lacking in wireless connectivity, there are two ways in which you can re-connect your printer to your network:
Software Setup 
The simplest route, if you happen to have another computer (Windows XP up to Windows 8.1) is to connect the printer to that via usb and click here to download the HP Printer Install Wizard.  You can use that utility to install the printer via usb and then convert the setup to wireless.  With that new wireless connection intact, you'll be able to click here and complete your printer-to-Mac Yosemite connection.
If you don't have a PC available to work with there is another setup option available that might work.  Try the following: 
Ad-Hoc Network Setup 
Access your printer's wireless menu from the front panel
Restore Network Defaults
Next, on your Mac, go into your wireless settings and choose the HP Setup network 
Next, open up Safari (or another browser) and type in 192.168.223.1 and hit Enter/Return to access your printer's Embedded Web Server.  
From there click on the Networking Tab and then click on the Wireless sub-menu heading 
Next, click to run the Wireless Setup Wizard
This will allow you to manually connect to your wireless network.  With that connection confirmed, click here to finish your printer setup on the Mac. 
Let me know if you run into any issues in either setup method presented above - I'm always happy to help.  
Have a great day and thanks again for posting in the HP Support Forum!

  • Unable to find wireless network on Photosmart C4780 on MacBook Pro running OS X 10.10.3

    I have been successfully using a Photosmart C4780 on my wireless network for a long time.  I had internet issues and the network name was changed.   Now I can't print wirelessly.  Tried reinstalling the software, but the program quits just before set-up.
    Help!!

    Hey there @physiocan!
    Thank you for posting on the HP Forums!
    I should be able to provide some suggestions that may get your Photosmart C4780 reconnected to your wireless network.  Due to the age of the printer there is no full feature software and driver developed for Mac 10.10.  Your printer requires the HP full feature software to setup the wireless through the USB cable.  Once the Wi-Fi is setup then the USB cable can be removed.  To reconfigure your printer to the new network name you will require a computer running the Windows operating system or a Mac with version 10.7 or lower.  
    Please post back and let me know!  You will only require another computer for the Wi-Fi setup.  Once the wireless is setup then you should be able to add it to your Mac 10.10 using the Apple Airprint drivers built into the Mac operating system.
    Thanks again for posting on the HP Forums!

  • Wirelessly connecting HP Photosmart 7510 printer to 64-bit Windows 7 computer

    I'm setting up a new printer, and I have never printed wirelessly before. The printer is connected to the wireless network, but the computer can't find it. The printer's wireless network test results show that wireless is working. When I install the HP photosmart software on the computer, and it gets to the "Network Check" window, it just stalls there without finding any printers. Obviously, the computer is connected to the wireless network because I'm posting this online. Seems like the problem is with the printer driver software? I also tried downloading the Home Network Diagnostic Utility. From there I was able to go to the printer page and print a test page. However, I still can't print anything from the computer. If I try to add a printer in the control panel, when I search for network printers the same thing happens. It just stalls there without finding anything. Using task manager to end the program is the only way to close the window once it gets stuck. Any ideas?

    AN IMPORTANT UPDATE!
    I had turned off my virus protection and firewall, and was still unable to connect to the printer, or ping it. 
    I could successfully ping the printer from my router, so I turned the router off and back on, re-configured the wireless setup on the printer, and I am able to connect and print again!
    Even though I could connect the printer to the router, and all of my computers were connected to the internet, something on the router was preventing me from connecting to the printer that was connected to the same network.
    So I've learned that I have a printer that works fine, but I own a crappy router. Hopefully this can help someone else.

  • Wireless connection from photosmart C4380 to HP Pavilion Home PC A340N running XP Home 32 bit.

    How do I get my printer to do wireless printing? What drivers do I need to install?  Do I need to setup a network?
    How do I get the printer to be set on "Direct?"  How do I get the printer to have the same SSID as my router?
    Presently, the blue wifi light is on, on the printer, so I know it is receiving a wifi signal, but the printer and router are not talking to each other because the printer will not print without the cable.  Also will this old model of printer ever be compatible with windows 8.1?  Or, my android phone-( using the eprint app).  Need help...Thanks in advance.

    Hi 2PHD-s,
    I'm sorry to hear you are having issues putting your Photosmart C4380 onto your home wireless network.
    I have included a document with detailed steps on how to get your printer onto your wireless network.  By following the steps in the document the printer should be on the same SSID as your router.
    The drivers for your printer for Windows 8.1 have been released now.  If you are upgrading your current XP machine, I would recommend that you uninstall the printer before doing the upgrade.  Once you have upgraded the computer to Windows 8.1 I recommend that you use HP's Printer Install Wizard for Windows 7 and Windows 8 as it will find the best driver for your printer.  
    For your question regarding printing from your Android phone, I have included another document about printing from your Android device with printers that don't have HP ePrint support.

  • 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, 

  • 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.

  • HP Photosmart C4780 problem with wireless connection & firewall

  • 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.....

  • 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.

  • Photosmart C4780 says wireless is on but computers say printer is not connected

    My Photosmart C4780 has always been temperamental with its wireless network connection; I have had the printer replaced once already and with both machines spent several days worth of hours on the phone to HP Helpdesks trying to uninstall and reinstall the drivers and additional software for various issues - either printer or scanner not working.
    Now the problem is that although the thing itself says that the wireless connection is on and working fine; none of the computers on my home network (Two PCs running Windows 7 32-bit; and two Macs running OS X Lion) are able to connect to the printer; no matter what I try it keeps saying the printer is offline.
    I would happily throw the thing in the rubbish bin to stop wasting any more time on it; but I have just bought 5 new (original HP  XL) cartridges for it and would hate to waste those.
    In fact the problems started when I replaced the cartridges; the alignment page at first refused to scan and when it did, it came up with an error message which unfortunately I can no longer remember exactly; something about the thing not being properly aligned and this may affect print quality.  I am assuming that this is what caused the problems; although why this would cause the computers on the network to say that the printer is offline I have no idea.  It has printed scanned images since then which came out fine; so the print quality can't have been that badly affected.
    Anyway, the thing is too old now to be able to call the HP helpdesk again (all of about two years old!) so I really don't know what else to do - apart from binning it and trying to get a refund on the three unused cartridges.  Oh, and buying a different make printer, obviously!  
    I have previously had a Photosmart 7350 which worked beautifully for many years, until I upgraded the computer to Vista and HP could not be bothered to provide updated drivers for it. The print quality of this one was what made me decide to go for HP again - a decision I seriously regret now!
    Does anyone have any ideas of how to get the thing working again; at least until I have time to properly research an alternative?
    Thank you

    When you say: "You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') to 250" what exactly do you mean?   All boxes on this page are completely blank; so what address should I put here?  Put the same address as the printer currently has, only substitute another number (like 250) for the number after the last '.' in the printer's current IP address.
    And when you say: "Enter your router's IP (on the Network Config Page) for the gateway." are you talking about the IP address that is printed in the confuguration summary underneath 'network name (SSID)' and 'hardware address (MAC)' as 'IP address'?  Or would this be the address to put in above?  The gateway address will be the same as the printer's, but will end in .1
    Thank you for your help so far; please clarify this.

  • Unable to connect to new wireless network in Mountain Lion with Photosmart C4780

    I have a Photosmart C4780 and have just upgraded my imac to Mountain Lion. HP are not providing new drivers for my printer as they say it will work with Mountain Lion. I have downloaded software updates. However, I have just changed my wireless network as I have a new broadband provider but am unable to connect to it. My problem is that the set up assistant software provided which I used originally to set up does not work with Mountain Lion.
    Any ideas please?

    I have solved my problem, I've bought an Epson. It works perfectly. If HP can treat their customers with such disinterest and contempt I don't want to give them my money. 

  • 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.
