Setting up my Photosmart c4780

I'm going away to college this fall for the first time. I bought an HP Photosmart c4780 for my laptop. I was wondering how to create a secure Ad Hoc network for the printer so that my roommate and I can use it without having to buy a wireless router (the University is still on a wired network). I tried to set it up at home first just to see how to do it, but I was unsuccessful. Any suggestions would be useful.
This question was solved.
View Solution.

To set up a peer-to-peer wireless network between your computer and your printer:
1. Reset your printer’s network settings to their factory default. (Scan > Network > Reset Network Defaults)
2. Make sure the printer’s wireless is on (blue light illuminated on the front).  (Scan > Network > Wireless)
3. Search for a local wireless network with a name “hpsetup".
4. Connect to the wireless network.  
The peer-to-peer network will not require a wireless password.
You can now install the software for your printer.  
5. When asked during the software install, select Through the Network, Network, or Wireless. 
The wording will depend on the version of software you are installing.  The software will automatically detect your printer over the network.
The printer should support up to 5 computers connected at once.
Now, you wanted a secure wireless network.  WEP is the only level of security available and, well, WEP is not at all secure.  It can be broken in about 10 minutes with freeware.
Still interested?  Are you sure you don't want to buy a cheap router and use that?  it will have the most modern security and it will not have to be connected to the Internet to work as a wireless print server.

  • Setting up MacBook Pro with HP Photosmart C4780

    I just bought my MacBook Pro and got an HP Photosmart C4780 printer with it. But I'm having trouble setting it up to work wirelessly (it's a wireless printer). It can't find my wireless network even though I'm sitting right next to it.
    Can someone help me please?

    I usually get the driver package off the HP website instead of using what's on the disk packed with the device.
    I just bought my MacBook Pro....
    If your MBP is truly "new" and not a pre-owned one that's new to you, there is a separate forum for the newer ones (black keys) here:
    http://discussions.apple.com/category.jspa?categoryID=251
    Their hardware is somewhat different than the older MMBP models covered in this forum so, should this be a hardware issue, someone in the other forum is more likely to have current experience with it.

  • 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!

  • 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.

  • Photosmart c4780 will not print in color

    Brand new to forums... I am using a MacBook Pro, OS 10.6.8. I recently bought a used photosmart c4780. The owner said it only prints black. When I set everything up, it wouldn't print at all, as the black ink was depleted. I replaced the black cartridge and now it prints. However, even though the color supply levels are at about half full, it will not print in colorI receive no error messages. Have tried different settings in the Print dialog options to no avail. Have not been able to find anything online that addresses this exact issue within the parameters as I've described them. Any help appreciated.

  • 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

    Thank you PrintDoc.  I'm afraid I don't completely understand your instructions.  I found the page you said to set a manual IP address, but then I got stuck:
    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

  • 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. 

  • 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.

  • Photosmart C4780 Windows 7 64bit connectivity problems

    Is there any link where I can download the full set of drivers to make Photosmart C4780 work on Windows 7 64 bit?
    Can I buy anywhere a CD contaning all required drivers to make this printer work with Windows 7 64bit.
    I have installed all updates from HP but I still can not make it work. (Win 7 32bit does recognise the printer and jobs are printed without any issue).
    In fact, I got so frustrated with the time I have lost over this issue that I bought a new Cannon printer. It worked instantly so it sloved the immediate problem for me.  But it would be still nice to get the HP printer working.
    Thanks,

    Hi,
    The drivers for your printer can be found on the following page:

  • Photosmart C4780 won't work with my new router.

    Hi
    I have been sent a new plusnet TG582n router after my old one broke and now my wireless printer won't work.
    I have tried uninstalling the software and connecting the printer via USB to reinstall on my windows 7 netbook but it came up with drivers failed to install.
    On my windows 8.1 laptop I have uninstalled and reinstalled and this was unable to complete. I have now done a restore to a previous setting on both of them so the software and drivers are still on.
    I have tried connecting my printer via USB cable but this tries to install the software again.
    If I go into devices my printer shows up with error and won't print.
    After trying all this I have now done a restore on the printer to factore settings (also trying the uninstall and reinstall via USB after this) and it still won't work.
    After doing a wireless test report it came up with my old ssid initially even after installing my new router which has a new ssid. After resetting the printer it now comes up with SigmaplusEOL1. It shows on the report that wirelss is on and working but ssid fail.
    I don't know what else to try as I have spent hours tyring different things and done trouble shooting several times.
    I have also been told by plusnet that t he routershould work for wireless n or wireless g.
    Please help!

    Hi Tazza,
    Welcome to the HP Forums! I understand that your HP Photosmart C4780, will not work with your new router. I am happy to help you with this!  I believe these following guides should help:
    The Printer is Not Found During Wireless Network Installation in Windows.
    Printer Does Not Maintain Wireless Connection.
    Just to make sure the hardware is functional, can you make copies standalone with the printer? Or what happens when you print a status report? Video of Printing a status report.
    Hope to hear from you, and thank you for posting!

  • Slow wireless printing on HP Photosmart C4780

    I am using the following hardware:
    HP Photosmart C4780
    Macbook Pro OS 10.6.7
    iMac OS 10.6.7
    Linksys E2000 router (previously Netgear router)
    When using the C4780 driver the wireless printing from both Mac computers is very slow and often won't finish on large jobs.  This was so frustrating that I went to using a long USB cable to print which worked just great.  I finally got fed up and went from an old Netgear router (802.11 b) to a new Linksys E2000 router.  The problem remained.  
    I read through the forums on this site and found that several people had success by using older HP Photosmart drivers.  I started with the HP P1100 driver and that worked great but color printing was poor quality.  I then read further that people had better luck with the HP Photosmart 2700 series driver.  I have switched both computers to this driver and things seem to work OK.  Printing is normal speed and I may be imagining things but I think the scanner capability hooks up quicker also.
    Someone at HP thought it might be a router problem.  How could that be?  I am on the 2nd router from a different company and fixed the problem by changing the driver only.  
    Here is my question:  
    Does HP have any plans to fix their HP Photosmart C4780 driver to work properly with OS X?  Given that I bought my printer with my Mac from the Apple online store I would think this is a priority but it has been months and no solution has showed up on any of the forums I have found.  Any help would be great.
    Thanks!

    OK, first are you positive that the HP software you loaded on your Mac is compatible with 10.6?  That is a common mistake that has special, non-obvious ways to correct.
    You could try to set a static IP address if the software is not an issue.
    Please advise on the software and we will go from there.

  • HP Photosmart C4780: Can't hook up wireless..Please Help

    I just bought a brand new IMAC and a brand new HP Photosmart C4780 wireless printer and a new Linksys WRT160N wireless-NBroadband Router. I go thru all the steps to set up and than get the error message the configuration failed and the software was unable to configure my device. The error message says :
    Ip Address: Failed to retrieve IP
    Subnet Mask : Failed to retrieve IP
    Default Gateway : Failed to retrieve IP
    Preferred DNS Server: Failed to retrieve IP
    Alternate DNS Server: Failed to retrieveIP
    I am clueless where to go from here. Can someone please help.
    Thank You
    Joe

    The Linksys WRT160N has WPS (Wi-Fi Protected Setup).  If you are using WPA-PSK encryption (recommended), then you can easily connect the C4780 to your wireless network using WPS:
    1) On the Linksys router, press the WPS button that is top of the case just under the Cisco label.  When the LED on the button starts to blink,  then the WPS process has started.
    2) On the C4780 printer:
    press the Scan Button
    select Wireless Menu
    select WPS
    select Push Button
    The printer should connect. 
    Since you have a new iMac running Snow Leopard, then all that is left to do is to install the SW.  Open the Print & Fax applet under System Preferences and press the [+] button.  Highlight your printer and press Add.
