Wireless printing disappeared

I have a color laserjet 2600N which I use with my Mac. My software it up to date.  I had been able to print wirelessly with my laptop and my iPhone.  Now, neither of those can find the printer.  Somehow the wireless connectivity of the printer has gone away.  Does anyone know how to fix this?  Thanks in advance for the help.

OK, tell me about your network - router brand/model, encryption type (WEP, WPA, etc) and ISP type (DSL, Cable, etc).
Also, when it shows offline, is it?  Print a Wireless Network Test from Setup > Network menu on the front of the printer.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

  • HP 7510 wireless printer disappears -- 4 station XP wireless network, w/ 1 PC hardwired.

    Printer: HP 7510
    Network:  multi-station wireless, thru DLink DI-632 (one PC hardwired to router)
    Address Config:   Printer is using static IP -- outside of DCHP range (192.168.15.240)
    Printer Config: Each computer has static IP set into the control panel app, using IP addressing.
    Operating System:  XP (Service Pack 3)
    Other devices:  Ipad, Xoom and Kindle Fire (all working using ePrint)
    Network Security Protocol: WEP (we're out in the country)
    Network Setup:  Main router, along with 2 access ports (hardwired); currently using channels 1, 5 and 11 (again, we're in the country and have little competition for channels)
    File Sharing: All machines in network have one open "share" drive, accessable with passwork.
    Scenario:  Wireless computers appear to stay connected for several days to a week at a time. (We reboot weekly, just as a SOP)
    Computer that is wired to the network loses communication with the printer a couple of times a day and needs to be rebooted in order to restore connection.
    When this happens, other machines continue to print and scan, with no problems, and the wired machine continues to have its name displayed in the SCANNING panel on the printer -- but the printer won't talk to it.   All network functions, including internet and intranet access to the printer's EWS is still available.  I have noticed that if I go into check ink levels, though, that the ink check software behaves differently. 
    Normally in the ink status app, there is a small "working" icon with 6 dots. When this computer is connected properly, it will start jumping around the circle, showing activitiy, get to 41%, and then display the ink status info.  When the printer/computer connection is not working, the "working" icon will go to just a couple of percent then jump to the printer information page, showing make, model, serial number, firmware level etc.
    In every instance so far, rebooting (with no other action) brings the printer/computer connection back to life -- until next time.  I am trying to find any other pattern for this behavior, just can't identify it yet.
    I started out with the plain vanilla installation, but then every computer in the network would consistently drop connections, about every 45 minutes. Using the info on this forum, I've eliminated the drop-outs for those printers, and got to the Static IP solutions (we've done that anyway for years with net-ready machines).  This is the last machine that "drops off"  It appears that some piece of HP-required software is "dropping out" or getting clobbered, but I cannot see a pattern, even checking and noting the various software used locally on the machine, and the various websites visited. So far, no pattern.
    I am hoping that an HP guru with access to the source for the "ink supply" status software can take a look at what is happening and why it will always go to 41% and then display ink status (when connected) and then only go a couple of percent and display the ink status (when it isn't connected).

  • HP 7510 AIO printer won't stay connected - Wired workstatio​n, wireless printer

    Hi!  I spoke (and checked solution button) too soon. The printer still "disappears" from the Wired XP network workstation. The only difference since applying the solution given is that the disconnects are now happening about every 12 hours, vs every couple of hours.
    Ink notification is set to "only when I print"
    Static IP is set for all machines
    HNDU works -- when the printer is visible but will hang the workstation if printer is not visible.

    More info:
    In last paragraph, above, the request for "ink status" is returned with a static display of the printer firmware version, driver version, step level, MAC# etc of the printer, not "ink status" when the printer is disconnected.
    Also, when printer is disconnected the HP home networking utility will hang the system -- a hard reboot is required, which restores the printer, until the next time it goes "into the woods".  Signal stregth, measured on the printer, is 4 bars (very good).

    Thanks!  That appears to solve the problem.  After your suggestion, I remembered that I set the "ink level warning" on this machine ONLY to "Always warn me", as opposed to "tell me only when I am printing".  That seemed to be the problem. Only the computer that was set to "always warn on low ink-levels" was disconnecting -- the others worked fine! Now, all are working fine.
    Just to be safe, though, I've also turned off the "scan from printer to computer" function on each computer. That was set for each machine, and seemed to work fine. The other machines in the network did not disconnect, and the printer was tracked whether each computer was on or off.   May try to turn it on later; I'll see if the family uses that feature very often!
    Thank you for your help.

    I spoke too soon!  After about 26 hours, the printer connection on the one "hard-wired" CPU dropped, which is better than before, but still not solid.  Same exact symptoms as before. Only piece of the puzzle that was different this time is about 50 pages were scanned, some to this computer.  Used the "Scan requested from CPU" process, rather than enabling the "Scan TO Cpu" function in the software app.  It did not drop the connection immediately after -- about 1 hour to 1.5 hours afterwards.  Suspect this is a coincidence, not a cause of the problem with this machine.
    I also scanned (same approach) from one other CPU on the network -- that wifi connection is still rock-solid.

    I think it is fixed now.....the problem seems to reside in the module that will notify you immediately if ink is low (vs notify me only when printing).  If, when initially installed, the user selects "immediately", then the printer will randomly disappear. (More on "re-finding it" later.)
    Also, it is difficult to change the ink notification setting, because it appears not to be "sticky", but will sometimes, flip. (I've not figured this out yet).  As long as the setting for "low ink notification" is on "only when printing", life is good.
    If the printer does disappear, go over to the Advanced tab when the printer software/firmware page comes up, instead of the current ink levels.  Reset the selection about "tell me about ink notification" to "only when printing", and then toggle the "autoshut off" from "NEVER" to "2 hours" and then, finally, back to "NEVER".  Then, lastly, press closed on the panel.  Printer should be connected again. To test, go to the Photosmart 7510 app again, and select "Show estimated ink levels".  The counter will start at 1%, jump to 41% and then bounce around until it displays the ink level.
    FOR HP TECH:  Please consider making the "ink level notification" persistent in the registry OR provide a de-install tool that will completely clean all traces of the prior installation of the 7510 driver / app in the registry, so that a new install may have this setting saved correctly.
    Hope this helps some of you -- it's an excellent printer once its running!

  • HP webservices tab not available when using HP Jetdirect 2700w wireless print server

    I recently bought HP Laserjet Enterprise 500 m551 dn color laser printer with HP jetdirect 2700w wireless print server ( one day old at this time).
    I was able to configure the device and enable/ use eprint services using the embedded server with a wired connection.
    However when I attach a the mentioned wireless print server, the "Webservices" tab disappears from the configuration website, the printer reports that the eprint services are not enabled and ofcourse hp eprint or google cloud print do not work. The printer appears offline at eprintcenter. Everything else works fine.
    On the product website for the wireless server, it clearly states that this is compatible with eprint services.
    What am I doing wrong.

  • My MacBook will no longer connect to my wireless printer.

    My MacBook (circa 2010 - it's not a MacBook Pro) stopped connecting wirelessly to my HP printer (3050 J610). I get a message, "Printer is offline." The printer is on and I have no trouble printing from my iMac. I appreciate any advice/insights. Thank you.

    Welcome to Apple Support Communities. We're all users here.
    There is a 'Reset Printing System' command:
    , System Preferences, Hardware, Print & Fax, right-click (Command-click) on the printer in question in the left column, as illustrated below, and select Reset Printing System.
    WARNING NOTE: This WILL delete all printers AND print cues AND saved settings, if you have saved your own 'custom settings' for the printer, and named them, such as 'Staples Glossy Photo-rear feed', those WILL disappear.
    Then you then will need to reinstall all printers, and re-create any custom settings, so if you have a lot of custom settings saved, make screen captures (+shift+3) for the things you customized BEFORE you reset.
    Yes, this is drastic, but if nothing else works, AND THE PROBLEM IS NOT CAUSED BY A PRINTER MALFUNCTION, this has always worked for me to cure my wireless print problems such as you describe.

  • Officejet Pro 8500a wireless printer hangs up when printing document.

    I have an officejet pro 8500a wireless printer and it has been working flawlessly.  Now all of a sudden it hangs up when sending a document to it.  It will say "now printing", with the red "x" and just sits there looking at me.  I have discovered that I can open the printer lid and close it and it will then print??????  
    Also when I click on "apps"on the printer menu screen,  it tells me, "unable to connect to the server".
    Anybody experience this problem??

    I too have this issue with my HP8500a Plus.
    I have managed to narrow down the issue to one of the cartridges. Whenever this cartridge is inside the printer, the issue will happen. If it's not, then the issue disappears!
    I have tested this discovery on TWO different hp8500a printers, and they both react to this "special" cartridge the same way: its presence inside the cartridge tray triggers the issue.
    There is only one thing that makes this cartridge any different form the other ones: even though it IS a genuine HP cartridge, it has been refilled and the max allowed page count has been hit. The issue started happening only after the max allowed page count has been hit.

  • Wireless printing problem in home network officejet 6700

    1.HP Officejet 6700 Premium

    3. My printer is connected to my house's wireless network and has accessibility to the internet, but when I try wireless printing from my iphone, ipad or macbook pro the printer "can not be seen". Saying " no air printers available".
    But if i unplug the printer's power and plug it back in, when it just gets connected to the wireless network again I am able to "see" the printer for a brief moment and thus I'm able to print. But a little while later disappears again.

  • 2101nw wireless print server

    When I use this print sever on my laptop nearly everytime I log on it crashes to a blue screen unfortunately it does not stay in this state long enough to get the error code.
    If I uninstall the server I get rid of this issue. I have tried using thelatest drivers but still get this issue. 
    I have no problems with using the server or printer apart from this. 
    Laptop is a Vaio with Windows Vista OS
    I have installed it on my old desktop with an XP OS with no issues.
    Anyone got any ideas 

    Hi,
    I have used this print server no problem since late June 09 then it refused to connect to my wireless network today.
    At noon, I checked the device status from my laptop and saw that there was one bar signal. I moved the print server closer to the wireless router but there was no improvement. At that time, I checked the router and it showed the device still connected to it. I could ping it from the router but I was unable to "connect" my laptop to it to print. After an hour or so it no longer connected to the router. I am pretty sure that I saw it dying.
    I decided to uninstall the software then reinstall it. When performing the re-installation, the software could detect my wireless network, but it failed to connect the print server to it. Manually entering the IP address, subnetmask, etc... does not help. I tried the reinstall on my wireless laptop and my wired desktop. In both case the software, via the print server I believe, showed the wireless networks in range and the signals strengths.
    I also notice that the wireless signal it detected was unstable, weak and strong at times, while in fact I checked all my other wireless laptops and devices (Blackberry, Epson wireless printer) receive excellent signal. This means THIS device reception is UNSTABLE and this might cause failure to connection.
    I have not changed anything of my network since the successful setup. The device just simply stopped recognizing the network.
    BTW, I use an IBM X61 laptop. It has no problem last two years until yesterday I got several blue screen of death. I notice this symptom disappeared since I removed the wireless print server software.
    I searched the support/faqs but I found no answer to this problem other than "checking the power" suggestion. I have not contacted HP yet. I hope HP can look into this matter an give some practical advice rather than asking me to check the power supplies of the device and the router.

  • HP AIO Remote shows wireless printer offline when it is online and can print to it.

    HP AIO Remote installed on my Windows 8.1 Yoga 2 shows my wireless printer is offline, when it is online and I can print to it wirelessly.  How can I get it to recognize my wireless printer is online wirelessly?  AIO Remote will only recognize the printer is online when the USB in connected to the Yoga 2.

    Hi rpmcintyre,
    Thank you for the additional information.  I apologize for misunderstanding. I just want to confirm that the HP AiO app that you downloaded onto your Windows 8.1 computer is showing your printer as offline when you are able to print wirelessly to the printer.
    I have two different documents for you.  The first one is How to Use the HP AiO Remote App for Windows 8.  It has a FAQ section at the bottom of the document with trouble shooting steps.  I have also included the Supported Printers for the HP Scan and Capture App.
    If the above documents don’t assist you, would you please let me know which make/model/product number of HP printer that you have? How Do I Find My Model Number or Product Number?

  • Resolution - Printing HP LaserJet & Linksys Wireless Print Server WPS54GU2

    Hello Guys:
    After trying to figure out for 10 days and calling HP, Applet and Linksys support, i finally am able to print to my printer.
    I have iMac running Tiger 10.4.8. I have a HP LaserJet 1012 Printer connected in a USB Port to the Wireless Print Server WPS54GU2. This is what I did to get it working.
    First install the following drivers:
    1) Go to http://www.linuxprinting.org/macosx/hpijs/ and download hpijs-foomatic-2.0.2.ppc.dmg and espgs-7.07.1.ppc.dmg file. Install hpijs first and espgs second.
    2) After that Go to Server Preferences, Double click on Print/Fax.
    3) Click on the "+" sign, select Line Printer Daemon - LPD
    4) In the Address field, enter the IP address of your print server.
    5) In the Queue name (This is very important). I used L2 for USB. You can try P1, L1 as well. Not sure how you have connected to the print server. For me L2 worked. I had tried using L1 and P1 and it didn't work for me.
    6) The Name field should automatically be populated.
    7) In the Print Using, select HP and then select "HP LaserJet 1012 Foomatic/hpijs" as the printer or whatever driver you have for your printer.
    8) Click on Add
    And now open up text edit or something and you should be able to print.
    let me know if there are any questions.

    Try Repairing permissions (Disk Utility). Then restart, then add again.
    What do you mean by the printer doesn't show up - the driver (print using:)?
    You can try the generic HP Photosmart P1100 Gimp-Print driver that comes in OS X.

  • Wireless printing to Canon MX310 fails using D-Link Router - Can't Connect

    I recently bought a D-Link wireless router (320), which supports wireless printing and I am trying to set it up to work with MBP. I set it up to run with Windows XP and it works fine with no problems, but with my MBP it won't work. Here is a screen shot showing the XP set up and the printer server info from the router (bottom).
    http://img338.imageshack.us/img338/1645/printerq.jpg
    From this, I've been using the following information to add the printer,
    Protocol: HP Jetdirect - Socket
    Address: 192.168.0.1
    Queue: lp1
    The printer shows up as idle in the printer selection menu. When I print it goes through the following messages,
    Connecting to Printer...
    Printer Online...
    Printing...
    And then the queue clears itself as if it printed, but nothing ever comes out of the printer. At first I assumed it was a problem with the router, but when I tested it with Windows it doesn't have any hang-ups.
    Any help would be appreciated with this, as I've read several posts and tried all recommendations but nothing will work. I'm also curious if I have the "Queue" in the printer dialogue right, or if it should be 9100. Thanks in advance!

    Based on your Windows port configuration, your Mac printer queue configuration is reasonably correct. Although based on your Windows port configuration, you don't seem to require a queue name of lp1 - this would normally be required for LPD connections.
    Your issue will be with the driver used. The Canon Mac drivers cannot be used when you have the printer connected to the USB port of a wireless router or print server (although the exception to this rule is an Airport device). When you have the printer connected via USB to a router or being shared by Windows, then you need to use a CUPS-based driver like Gutenprint or PrintFab (yes I know the Canon driver says CUPS but it is not true CUPS).
    The Gutenprint tends to be the preferred driver because it is free, however your MX310 is not listed as a supported model so you would have to experiment with using a model that is supported and this can waste a lot of time and ink/paper.
    PrintFab (www.printfab.net) costs 49 Euro but it does support your MX310. A trial version is also available so you could see if the printer does work before making a purchase.
    One final note. For your Windows queue you don't need to add the colon 9100 after the IP address. The fact that you have selected RAW and have 9100 set for the Port Number is adequate.
