• HP Photosmart C4780 problem with WiFi connection and firewall

  Hello

  I'm trying to connect my HP Photosmart C4780 to my network at home.

  Whenever I try to set up my printer to my wireless network, I get the following HP Network Diagnostics Error Message:

  Problems may exist with functions of the network printer.  Please try to solve the problem, and then click Retry, or click next to continue.  See below for details.

  Your printer is unable to communicate with your printer at 192.168.1.69.  This can be the result of firewall software.  If you use a software firewall check that the 427 UDP port is unlocked for the incoming and outgoing traffic.

  Your PC cannot communicate with your printer at address 192.168.1.69.  Check all cable connections.  Make sure the printer and the PC and the router are powered on and connected to the network.

  MY REQUEST - I have AVG 2011 software installed on my laptop which I assume security contains a firewall.  But I don't know how to "check that the 427 UDP port is unlocked for the incoming and outgoing traffic".  How can I do this?

  I only am not a tech expert so would like as much help as possible with that at the moment I can't use my printer because it keps showing offline.

  Thank you very much

  Brilliant, Yes, thank you, that did the trick!

• Photosmart 7520, impossible to reinstall the printer after removing software

  Name of the product and operating system: Photosmart 7520, Windows 7 32 bit.

  Description of the problem:

  I tried a lot already if the description is quite long, bear with me here.

  At the beginning everything worked well. After a few months, the printer was not capable of scanning more computers in the network. He could identify them, he was not able to transfer the scanned document. Printing from computers was still possible. I did first network tests, even reset network to factory settings, but everything was fine. Try to solve this problem, I ran HP print and scan the doctor, the program gave me a twain scan error and was not able to fix it. Because it was not able to fix it. I uninstalled the computer HP printing software, reinstall the printer completely and try if it works. Digitization (magicly) now works on my other computer, but I can not reinstall the printer on the computer where I uninstalled the software, because it is impossible to find the printer on the network. I also tried to connect the USB printer, without a bit of luck. I think it's a driver problem, because the computer seems to have many 7520 drivers broken out there. I hope someone has a way to help me, because I don't know what to do anymore...

  A few weeks ago, I've been here for more help (see: http://h30434.www3.hp.com/t5/Printer-Software-and-Drivers/B110-doesn-t-print-wireless-anymore-after-... )

  Then, after you apply the advice of sabretooth04 (manually in the WAP code on the LCD of the printer, it worked perfectly... until :-(a few days ago)

  Although nothing has changed: no new software, no change of position... nothing!

  Then I restarted the router, then the printer and the laptop; Once again put in the WAP code... but it does not help :-(

  The printer is doing well: all the test pages out big, like the wireless network test page.

  Please, I really need help (again)

  Greetings from the Netherlands,

  Sigrid

  P.S., as wireless worked from day one, I never used the cable and now I can not find. So for the moment I have no alternative wireless...

• Problem Printing Photosmart C4780

  I just purchased the Photosmart C4780 and installed on my iMac running on an OS 10.6.4.

  The printer is connected ok as I can scan, but I cannot print. In the print queue status 'error', but I can not get this error information. I did all the steps of the guide here and still no joy.

  The installed widget is constantly saying "loading information...". "and the"HP Utility"does not open, is this related to the printing error?

  I'd appreciate any help on this!

  OK, if you have ALREADY loaded the software from the CD, and unless your CD says it supports in particular 10.6 Snow Leopard, you must uninstall it using the option "scrubber":

  Go to Applications/Hewlett Packard / click Uninstall HP
  Click on continue
  Highlight your device in the left pane
  Hold down the Ctrl and Opt Cmd and click on uninstall
  There will be a pop up that asks if you are sure you want to uninstall all hp software. (At this point, if you continue, all HP printers you have installed will need to be reinstalled)
  Click on continue and let it finish

  Restart your Mac

  Now run a software update.

  Then, remove and reinstall the printer in System Preferences, Print & Fax.

  You do not have the software now since Snow Leopard as well print & scan drivers built-in. scan from Preview apps or Image Capture. Scan from the front panel of the printer does not work yet.

• HP Photosmart C4780 cannot print (communicate) with Windows 8 Dell desktop

  Product name: HP Photosmart C4780

  Operating system: Windows 8 64-bit

  Error message: "the computer is unable to establish two-way communication with the device.

  Changes: I installed the "full functionality" print driver available on hp.com for Windows 8

  Description:

  When I send a Word Document to print the C4780 will spit on white paper.  I think that the ink levels are cool, but when I try to check the ink levels using the Toolbox "printer" in the HP Solution Center, I see the error message (see above).

  I've uninstalled and reinstalled the driver updated several times now. Whenever the installation seems to have success, but it does not solve the problem.  I also tried to install the driver of "basic" printing for the Photosmart series, but I still have the same question.

  The printer is connected to the computer via a USB cable; I'm not currently using the wireless feature.  Thank you for your help with this.

  Hello

  You indicated that you could not communicate with the printer, but I can tell that it prints a blank page of the word.

• Photosmart C4780 - prints extra page even after update HP driver

  With the Mavericks (OS X 10.9.4) installed, I noticed that completed print jobs remain in the queue for my HP Photosmart C4780 Safari printing and preview.  If I want to print another (another page), I usually have to remove the previous work (100% full) of the queue so that the printer will print (I think remember that sometimes, with a Google Chrome browser, it is not necessary).  If I close the lid of my MacBook Pro (which goes to sleep) with a completed print job stays in queue HP, it will be then print again for a second time.

  Today, I installed the updated driver, but the problem has not disappeared when I tried to print from Safari and overview.

  HP Print Driver Update critical for printing a foreign page address - 2014-01-31, Version1.0.0, 10.56 M

  Any ideas of how to solve my problem?

  You have an old HP software in your Applications folder, which was the Mavericks before OS?

  In the meantime, download and install this: http://support.apple.com/kb/DL907
  
  Restart your Mac.

  Reset the printing system:
  
  -Go to System Preferences > print & Scan
  -Right (or control) click in the rectangle listing your printers and select Reset Printing System.
  WARNING - This will remove ALL your printers!
  -Select the sign more to add a printer. Select the default tab on the top of the window. Search for the printer, select it, and then beside the dropdown 'Use', select the model of the printer (not AirPrint). Wait for the 'Add' button becomes available. Until it clicks.

• HP Photosmart C4780: HP Photosmart C4780 printer does not print

  The printer does not print. It turns on and can scan and all that, but when I try to print it fair shoots on a single page. I checked my drivers and ink, both are very good. I've done the Troubleshooting Wizard HP and it has never worked (I tried 3 times and he said that the event was canceled somehow). I tried calling HP, but my printer is "more served by HP" (it's what tells me the site). Help

  @raygun11, welcome to the forums!

  I'm here to try to help you with the problem you are having with your Photosmart C4780 white pages print, and I hope we can solve it!

  I would like first of all for you to tell me if there are problems when you make copies, black and white copies and color.

  Try a power reset if you haven't already and make sure that the printer is plugged directly into the wall, avoiding bars power and surge protectors. This ensures that the printer is full on.

  Reset instructions:
  Press the power button to turn the product on.
  With the product, unplug the power cord from the back of the product.
  Unplug the power cord from the wall outlet.
  Wait at least 15 seconds.
  Plug the power cord into the wall outlet.
  Reconnect the power cord to the back of the product.
  If the product does not light by itself, press the Power button to turn it on.

  Also run Print and Scan your PC of Windows 8 doctor , chose the option "Print of difficulty" and let me know that say the results at the end try printing out in Notepad too and I would like to know if the page is empty, or print very well.

  I hope to hear the results of your part, and we'll go from there!

• Is it possible to connect the HP Photosmart C4780 Wireless printer without USB cable?

  Hello

  My family and I recently moved and while moving, something inevitably get lost or left for account.  I am fighting to get this printer and will so I don't have to bother people at the front desk at school to print my documents for me.  I have lost/misplaced both the HP Photosmart C4780 printer software disk and the USB cable.  I have no idea where these things are and have not found them within two months, we've been in the new House.

  I solved the issue of the loss of the installation disk by downloading it from the HP site.  My problem is now getting beyond the USB connection and get the currently installed software.  Because I run on a MacBook Pro, it always tells me that I need the USB key to continue the installation.  I'm on a Verizon Wireless router, and I even tried to find the printer on my wireless network with no luck.

  Help, please!

  Thank you.

  It's the type of cable you will need (ignore the color of the cable, the ends are the important part).

  

  Have a new router is not a problem, but remember the SSID and password wireless exactly, otherwise it will not work (if you decide to try Method 1). It's a bit like "trick" your printer into thinking that your new router is your old a long enough to configure the network settings for the new (desired).

• HP Photosmart C4780 won't print from my wireless laptop.

  I have a Photosmart C4780 who don't print to my HP laptop.  I have a Cisco Linkys router connected to a modem Rogers.  My laptop shows an error in the printer.  Can you please help me.

  Oh, you must keep the firewall on the installation.  The installation software configures the firewall for your installation.

  I reinstall the printer with the active firewall.  Go to control panel > printers & devices and delete the printer.  Then click Start > all programs > Hewlett-Packard > C4700 series and 'add a device '.  All this with your firewall active.

• I have the hp photosmart c4780 who does not the computer print

  I have a HP Photosmart C4780 that will scan documents, photos and will copy fine, but when I want to print something from my computer it will not print it. It will send things scanned to file appropriate as well fine. I ran diagnostics, reloaded the startup disk, and he says it's very good. My operating system is Windows Vista.

  How is the printer connected?  What happens when you send the print jobs to the printer - they remain in the print queue or just disappear?  Are there any error messages?

  Running the diagnostics to http://www.hp.com/go/tools can help solve the problem.
