H P Photosmart C4780: hoo wireless printer

my computer HP laptop, OS 8.1, has been printing my C4780 without any problem at all. Last week, comcast was dealing with another issue and replaced the comcast modem and Linksys router with the modem/router combo. Since then, the printer displays error and will not print. I had an impression that he cannot read the SIDD, said. Since there is no keyboard on the printer, how do I give the SIDD. I already spoke with Comcast several times and, although they tried, they thought that it better for me to deal with you. It was quite frustrating. Can you help me please? IKE

  • All-in-one HP Photosmart Plus B209a wireless - printer problems

    I plug just this printer 2 weeks ago and there are already problems! A few days ago, I went to print something a TI never printed, so I checkd the queue and it says the printer is offline. I checked and the 'use printer offline' option has NOT been verified. I googled looking for help offline wireless printer and came across some tips to restart the spool.and then unplug and plug back into the printer, so I did and he went online and I was able to print 1 document of 4 pages. But after this document, I tried to print another document, and it said "error-printing" in the queue. So today, after that I restarted my computer, it worked well again - for a document. Then he returned to offline mode. So I watched fo more help online. I tried making sure the correct port with my printers IP address has been verified and he was, and I tried to uninstall and reintalling the drivers that did not help. I basically tried everyting on the HP support on the topic page and nothings worked. But it peprfectly worked well for a week so I don't see why it would be to have these problems now?

    Also, I tried to print a document 2 faces a few days (before the issuance of all offline). I went to the printing preferences, click on 'manual' under duplex print, then ok, and it printed all the odd pages, as it was supposed to. Then the screen came from promting me to take the paper in the output tray and the tray and click on continue so I did. I waited and waited and waited for a good 10 minutes and never even printed pages. In the queue it sad it was printing, but it wasn't. I cancelled the document and just tried to print a document face a regular to see if this works-it printed fine. So I tried printing 2 - against new and it's the same as before.

    The laptop I am I am trying to print from is a Sony Vaio CR320 running on Windows Vista. I have not instaled anything new in the last week, so I know there are no new program interfering. Also, I have not removed any programs.

    Any ideas? I am a student and I am a little lost without a printer lol :/

    OK, time to bring in power tools.  Download, install and run this tool.  He should tell us what is happening.  Run it when the printer shows offline.

  • Photosmart c4780, I - Mac - printing Photos

    When you print pictures, there are pale lines through printing. What is a cleaning problem? If so, how do I clean the heads?

    You can pull the carts and see if they are blocked on the bottom with the ink and other things.

    Check the ink levels.  When they become weak, some nozzles do not receive enough ink to the fire.

    Check your print quality settings.  It should be the best in the pilot for maximum coverage.

    Finally, try different carts

  • Photosmart C4780 wireless Mac connection failure

    I, like some others I've seen messages on, will have exactly the same problem with my HP Photosmart C4780 of wireless connection to my MacBook.  I just bought this printer a couple of days with a new iMac (which I have not yet unpacked, yet).  I decided to see if I could go ahead and get the printer works with my Macbook.  Here is a breakdown of the specs, measures and tests.

    1 MacBook OS X 10.5.8 (Leopard) running.

    2. software is installed.

    3. to set up a wireless connection, the "Device unavailable" error appears in a dialog box.  This is the same error that others have had.  He continues with... "The network configuration has been correctly transferred to the device.  However, to continue the configuration of the device in the network, your Mac must have access to the device... ».

    4. I can load the page HTTP for my router (a Qwest Actiontec M1000) and see the IP address of the printer.

    5. I can successfully ping the the IP address Mac printers.

    6. I cannot correctly load the HTTP page to the printer via the IP address and the view that it is different pages.  I can even change some of the settings, however, apparently never really complete updates.

    7. After talking with HP support for more than 90 minutes (after waiting on hold for nearly 45 minutes, not a joke), we arrived at the conclusion that the modem/router must be the cause of the problem.  So, I was told to contact Qwest to get help.  Furthermore, technical support had me through many of the same steps I've seen on other items (for example, reset the printing system, uninstalling and reinstalling the software, reset my router, etc.).

    8 next, before calling Qwest, I decided to see if I could get the printer runs on Windows.  Under WinXP SP2 on a platform completely separate (but), I was able to install the software correctly and successfully a wireless connection to the printer.  I rebooted the machine Windows several times and disconnected the power to the printer just to make the connection is when it was re-powered and rebooted.  And Yes, everything works perfectly on the Windows machine.  It tells me there is nothing wrong with the router (with a possible exception, which I will speak in a moment).

    9. given that the installation worked in the windows box, I decided to call HP.  This time I isn't that hold it for about 20 min.  I told them what the results were in the Windows world, and we proceeded to work on this issue with the Mac for about an hour.  We have made some of the same things, as for the first phone call, in addition to a few other checks.  It simply seems that software on Mac just cannot see the printer, which means that the HP software will be unable to see it as well.  It's very weird because I can still ping and also set up its Web page (on the Mac and Windows machines).  Now technology seems to think that this is a problem with Mac OS because it certainly works with a different OS with the same router.  I'm leaning toward the same conclusion as well.

    10. now for the question of the possible router I mentioned earlier.  I saw in another post where someone says hello.  Something the Actiontec only modems no routing of packets used by Hello.  I have absolutely no idea what the Hello devil is.  I tried to do a little research on this and am still confused as to what it is and what it does.  However, if Hello is something specific to the Mac and has nothing to do with the router itself, then it seems to me that the router had no knowledge of Hello (and certainly would not care).  Therefore, the ability of routers delivers packages for different platforms should not be affected by this Hello thing.  However, this does not mean the packets are not getting lost once they arrive at the Mac because of Hello (again, not knowing what it is).  Now if that's the case, then it seems to me that the problem would be with the Mac (in conjunction with this thing Hello), not the router.

    11. other positions reported this same problem wireless with this same printer using OS X 10.6 (Snow Leopard).  If this is true, then when I finally unpack my new iMac, I expect to have the same problem... we'll see when I am near to it.  If he did not have this same problem, so maybe there is hope if I upgrade my MacBook to Snow Leopard.

    If anyone has any other light to this problem, please let me know what might be the underlying issue, and how can I fix this (if someone already has).  Thank you.

    Finally, problem solved!  Here is the solution, if someone else is facing a similar problem.

    Since I found the IP address of the printer on the Web page of my router, I went in "Print and Fax" system preferences.  From there, I clicked on the sign "+" to add a printer.  Nothing appears in the default tab.  So, I went to the IP tab.  From there, I selected the Protocol for the "HP Jetdirect - Socket".  In the address field, I entered the IP address of the printer.  After a few moments, the printer was found and the field "Print using" is automatically filled with the print driver.  I clicked on "Add", and low and here's the printer now appears in my list of printers.

    The second representative of HP I was working with me had to go through this same series of steps with one exception.  Never, we put the Protocol field.  He was left as default "Line Printer Daemon - LPD".  When this was done, nothing ever appeared.  So, I think that the trick was to change the field Protocol, as shown here.

    I hope this helps those who have a similar problem.  Good luck.

  • HP Pavilion Touchsmart 15 Note: hp photosmart wireless printer does not print

    I have a Photosmart eStn 510 wireless printer series, which comes as default printer and seems active (not offline). When I print something - and I tried different programs - the document appears in the print queue, says it's printing, but nothing prints. If I restart my computer, the document will print until I connect. I tried stop the print spooler, but then couldn't do restart.  I looked at the printer using the HP Solution Center, and he says he's online.

    I have printed successfully to this printer wireless until I upgraded to 8.1.

    Thanks in adance for your help.

  • 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!

  • Network out of range for my HP photosmart C4780

    Hello.

    I'm trying to implement my photosmart C4780 for wireless connection. I select my network wireless in HP Setup, and press to continue. After a second or two, I get the following error: "network name" selected WI-Fi network is not within reach of the unit. I have the option again or change network. The wireless router is placed not more than two feet from the printer, so I don't think that the distance is the question.

    My wireless router is an Airport express, put in place with a WPA2 passphrase.

    The computer I'm in the form of installation software is a bit macbook OS. X 10.5.8

    Cordially Krisrogeb

    Well, it seems I've found the problem. Do not put your laptop between the printer and the router. The printer wil not be able to sort the signals apart.

  • Photosmart B110 (CB4F28)-l' printer does not

    I have a Photosmart B110 series wireless printer, which has suddenly refused to print. I have a PC with windows 8 and good drive installed. HP printer control shows the printer as offline, but when I run the Test report wireless and HP Network Configuration - everything seems fine.

    All print jobs are displayed as of mistakes and being held in a queue.

    I don't know what the problem is - can you help me.

    Thank you very much

    Thank you very much for this - that I had lived this routine (a few times) without success, unfortunately. I think it was a problem of Windows 8 that all my PSA had gone offline, even if the computer and diagnosis reports showed as being online.
    I now managed to get all the elements, including the printer by fiddling with the setup - file but don't know how!
    Anyway thanks a lot for your answer

  • HP Photosmart C4780 prints wireless but does not scan.

    I have a HP Photosmart C4780, which works great on USB, but only print via a wireless connection.  This model may be able to analysis via the wifi connection?  I have an IBM T23 running Windows XP SP3 with all updates.  I see the CD-ROM driver I have is version 14.1.0 which is the latest version online also.  I missed something in the installation that makes possible the wifi connected to scan?  I saw a USB connection through the room, when I want to scan anything.

  • 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).

  • Photosmart C4780 wireless do not print wireless

    The basics - old iMac dual core, new Macbook (both with Snow Lepoard 10.6.1,) relatively new Airport Extreme, new printer 'Wireless' Photosmart C4780.

    Installation/set up progresses to a point, then I get the message "network unavailable. The selected WiFi network is not in range of the aircraft. "The 'device' the C4780 sits 3 feet between the router and showing the strength of the signal higher of all networks in the region.  [BTW - the new Macbook would work wireless from time to time until people e-mail tech support HP's suggestion, I have made an adjustment to the configuration of the router.  Now it works again even if the router settings are returned to their default value.  When you attempt to print wireless from a computer, the printer says it is offline.  I talked to Apple support and they advise that if I can get the IP number of the HP printer, I should be able to configure the printers to work.  HP technical support 'Chat', explains the IP number is assigned by the router.  I've given up o HP Webcam live tech support after being on hold for over a half hour, twice.  HP support 'Chat' is almost exclusively oriented Windows and they send me to technical support of HP "e-mail", which sends an email per day reiterating I already took action.  Sorry for the rant, but this forum is my last hope.  Can someone help me? What can I do to get this working?

    Have you deleted and added the printer in the print queue? Let's try it:

    -Sys Prefs, Print & Fax
    -Select the printer in question and click the sign less down the list
    -Select the sign and add it again.

    If this does not work, do the same thing, only instead of the second stage, right (control), click the box of the print queue and select Reset Printing System.
