I have an HP OJ 8500 Pro wireless that won't print via wifi.

The printer shows connected to the WIFI, however I can no longer print via wifi.  I can print via USB.  Any ideas?

  • Officejet Pro 8500 A909g Wireless suddenly won't print yellow; no error messages

    Is it possible that a printhead needs to be replaced even when Diagnostics Pages all say "Printhead health:  Good"?   I don't have any error messages.  There are no obvious white lines through the colored blocks on test pages.  In a couple of blocks on some test pages, there is one, very fine, barely visible line, but it's not the same on all pages.  (Today I've printed about a dozen test pages of three different kinds that have colored blocks on them, and there are no white lines like the ones shown in examples of bad test results.)   I have used the tool for cleaning the printheads many, many times today and have cleaned at all of the levels.  The ink level in the yellow cartridge is fine, and it's been working well until yesterday and today. 
    The printing of the five colored blocks on test pages is good, bright, and clear.  The only problem is that the block which is supposed to be a light orange color is only pink, and the block that is supposed to be green is only blue:  they are lacking yellow ink.
    I haven't had any problems with the paper I've bought at Staples for six years (I also bought my printer at Staples ).  The printer is six years old but has not been used hard.  I use it regularly for a page or two a few times a week, so the printer isn't sitting idle for weeks at a time. 
    I read something in "help" information about using a straight pin to gently remove excess adhesive from the nozzle of a new ink cartridge, which didn't apply to my cartridge, but I decided to experiment anyway by pushing a pin through the nozzle of the partially-used, yellow ink cartridge,  The test page I printed after that is the page with just four colored blocks on it rather than the five blocks on a different test page.  This is the only time in two days that the yellow ink has printed.  However, it printed in a wide horizontal band a little streaked with gray in the middle of the block.  Then there are fairly wide white bands (no ink) both above and below the wide yellow/gray streaked band in the middle, and there are very narrow, yellow, horizontal strips  printed along the very top edge and the very bottom edge of the block.  In other words, the sequence of horizontal printing in this block only is:  narrow yellow strip, wide white band, very wide yellow/gray streaked band, wide white band, and narrow yellow strip.
    It seems this might mean that some yellow ink actually got through after I'd poked the pin into the center of the nozzle of the partially-used ink cartridge?  However, when I tried printing the same test page again, there was no color, no ink showing at all where the partially-printed, yellow block had been on the previous test page.  There was only a totally blank, white space where the yellow test block was supposed to be.  The blue block, the red/pink block, and the black/gray block all printed well.
    When nothing solved the problem of yellow ink not printing, I replaced the partially-used, yellow cartridge with a new yellow cartridge, but that didn't make a difference either:  the yellow ink is still not printing.  Yes, I use genuine HP ink cartridges.  I buy new ones whenever I need them -- never refill them or use any other brand but HP. 
    I used the alignment tool once to fix some slight wavering in the lines on a test page.  The lines are now perfectly straight.
    I apologize for being so wordy, but I wanted to send all of the details that might help diagnose the problem.  I read other questions and answers in the forum about yellow ink not printing, but while there were some similiarities, none of them was 100% exactly like my experience with the problem.  What shall I try now?  Thank you for any suggestions.

    Good day.

    how can i connect my macbook pro wirelessly to an hp printer with a asus rt 66acr router?

    Firstly, the HP printer must be connected to the ASUS' network. Then, simply connect your MBP to the network and your printer should be addable in Print & Fax in System Preferences.

    I have an older Airport Extreme (disc shaped) that we use with my wife's PowerBook (OS 10.5.8) and my MacBook Pro (OS 10.9.4).  We currently only have Airport Utility on her Mac, but I want to upgrade the utility so I can use it on mine. Which version of the utility will work on my MacBook, and still control the older Airport Extreme?

    if I update the Airport to the latest version, and "control" it with my MacBook Pro, will the older G4 still be able to use the signal from the new Airport?
    Yes. Your G4 shouldn't have any difficulty connecting to a Wi-Fi network provided by the latest 802.11ac AirPorts as they support the earlier radio modes that the G4 uses.

  • HT201364 I have a brand new macbook pro, but it won't let me download mavericks

    I have a brand new macbook pro, but it won't let me download mavericks

    You have got a Late 2013 MacBook Pro.
    This MacBook uses a special OS X Mavericks version which is newer than the one available in the Mac App Store, so you cannot download OS X Mavericks from the Mac App Store now. Instead, if you need to reinstall OS X, you will have to do this through Recovery (hold Command and R keys while your computer is starting up).
    You will be able to download OS X Mavericks from the Mac App Store when your Mac uses the same OS X version as all other Macs. This may happen when Apple launches OS X 10.9.2

  • Macbook Pro can't find Canon MG6350 via wifi

    Macbook Pro purchased earlier this year and running OS X (10.9.1) can no longer find my new Canon MG6350 printer via wifi. Printer can also not be found by other new Macbook Pro, iPad Air or iPhones.
    I have reset Canon printer, Macbook Pro printer system, downloaded latest drivers, tried inputing Canon printer IP address. Nothing works permanently. I temporary resolved issue by re-enabling Boujour on Canon printer settings, which magically allowed printer to appear on all devices, but this "fix" has now stopped working. Can also see all devices on BT Home Hub 3 when logged in as administrator.
    I can print via USB, but want wifi printing to work. Very frustrated, as it worked brilliantly before latest OS X / iOS upgrades. Any suggestions or help appreciated.

    Thank you for your interest Clinton.
    Yes of course the printer connected to the wifi network. I can see all devices including the printer when logged on as Administrator on the BT Home Hub. I have also reset the Hub itself several times and reconnected all devices.
    Note that I had no problem setting up the printer and all devices wirelessly on the network previously, and that this exact setup was working for months brilliantly and without issue until roughly the time I upgraded to the latest releases of OS and iOS on all my Apple devices.
    I have also reset the printer to its factory setting several times, reconnected all devices to the network numerous times and have spent roughly four hours trying everything I can think of on both the printer and Mac to no avail. Hence my post. And yes all devices have the latest drivers as indicated by Apple and Canon.

  • Hp laserjet pro 200 My won't print more than 1 file at a time

    My hp laserjet pro 200 m251 won't print more than 1 file at a time. Any ideas?

    Hi @nocastaway,
    I see by your post that you can't print multiple copies. I can help you with this.
    From the application your printing from, go to File, Print, Number of copies select 2. Uncheck Collate. You can now change the number of copies. Collate should now stay unchecked.
    Try printing the multiple page document again.
    You might have to disable all the startup items, to see if there is another program causing this issue.
    How to use MSCONFIG. Click on the Startup tab and disable all.
    Test the printer.
    Then go back in and enable all from the Startup tab.
    Download and run the Print and Scan Doctor if you are still having issues. It will diagnose the issue and might automatically resolve it. Find and fix common printer problems using HP diagnostic tools for Windows?
    What applications have you tried?
    How is the printer connected? (USB/Ethernet/Wireless)
    What operating system are you using? How to Find the Windows Edition and Version on Your Computer.
    What were the results when you ran the Print and Scan Doctor? (did it print or scan, any error messages)
    If you need further assistance, just let me know.
    Have a nice day!

  • Macbook pro with osx 10.8.5 won't find epson printer via wifi

    i have tried every option i found on-line.  i inserted driver cd to no avail.  help with getting macbook pro to recognize printer via wifi please.

    So Does Maverick Fix this issue?
    Im trying to sort out my inlaws wireless printing issues. They have a mac running 10.6.8 works fine wirelessly and USB. They have another mac running 10.8.5 and this mac will not see the printer directly. I can print via mac 1 using a shared connection. But if you deselect mac 1 sharing options then mac 2 cannot see the printer. I can print via usb and via the shared connection using mac 1. But not directly.... So if Bonjour is no good on 10.8.5 does the update to mavericks fix it?
    Thanks

  • HP LaserJet Pro 200 m251 won't print PDF

    I have an HP Laserjet Pro 200 that will not print PDFs.  The documents get stuck in the print queue and I have to delete them and restart the printer.  I have reinstalled the driver and updates and reinstalled Adobe Reader and updates.  Called HP and they told me to contact ADobe, but I can't find a number.

    I posted this on another discussion.  But here it is again.
    One of the things I have experienced in the past with printing PDFs is that it would hang in the print queue. There is a manual method of deleting the print documents in the print queue. But the issue is printing PDF documents that are scanned in and has maybe highlighted text or handwritten notes on the PDF. The printer driver can render it correctly if printing the PDF as a text document. What you have to do is change it so that it prints as a PDF image instead.
    To print as an image, open the PDF then click File then click Print. Click the Advanced button on the following window that pops up and select the check box "Print as image".
    Now to clear your print queue will be key prior to doing this if the print job is hung in the print queue.
    Here is a Microsoft KB Article that explains how to do this. I think it has an available Microsoft Fixit tool you can use as well.

  • HP OfficeJet Pro L7590 suddenly won't print yellow ink.

    My OfficeJet Pro L7590 suddenly won't print yellow ink.  The cartridge isn't empty.  It still prints everything else.  Things that require yellow ink come out a different color (ie: green comes out blue).  I've cleaned the printheads several times from the "tools" menu and the report says the printheads are in "good" condition.  I've also tried soaking the printheads in hot water for 5 min like was mentioned on here.  Still nothing.  Any suggestions?

    Hi - you've worked through all the steps in the support document here? http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01957673&tmp_task=solveCategory&lc=en&dlc=en&cc... 
    If you have, and still see bad red and green blocks on the PQ Diagnostic page (as described in the document), you may have to replace the black/yellow printhead (even if the printhead health is reported as 'good'). You can check your warranty on that printhead here: http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&lang=en&docname=c00206040

  • Acrobat Pro XI Mac won't print a .pdf file, but Apple Preview will print correctly

    Hello,
    I have Acrobat Pro XI for Mac.  recently I've run into pdf files that will show the document on screen ok, show up on print preview screen ok, but when I send it to a printer I either get:
    1.  no printout... the document passes through the printer queue ok, but nothing comes out (no blank paper, nothing).  no data seems to even reach the printer/print server.  no error.  the print job basically vanishes into thin air like the job was never sent
    2.  prints out with all the characters of a text substituted with squares (again, no error. just prints squares instead of text)
    But when I print the same document using Apple's Preview program on the same machine, the file prints out fine.
    I experience this problem with two different Macs, with two different OS versions.  Again both machines will print the .pdf file fine using Apple Preview, but not with Acrobat Pro XI.
    I've searched for this problem, but no one seems to have this problem. I've tried just printing one page, etc., and no difference (won't print, or print wrong using Acrobat, but prints fine using Preview)
    the files are typically sent via e-mail from a vendor, or a web downloaded form (invoice, forms filled out.  some are secure, some are not).  and these are from multiple sources.
    Any ideas what might be the problem, and how to fix this?
    system:
    Mac Pro (early 2008) and MacBook Pro (mid-2011)
    MacOS 10.8.4 and 10.6.8 (multiple computers have this same problem)
    Acrobat Pro XI, 11.0.04
    printer: HP LaserJet 5MP (yes.. old.. but it works) via HP JetDirect + print server on  LAN

    I just found this solution on another board, I tried it  (I removed the same file listed below) and it worked for me.... 
    Safari won’t save or print PDFs: how to fix
    :: Tuesday, January 29th, 2013 @ 5:29:46 am
    :: Tags: Computers
    If Safari won’t save or print PDFs (but views them without any problems), you probably have an Adobe PDF plug-in installed. In Safari, go to Help->Installed Plug-ins and do a search for “PDF.” If you have anything with “PDF” in it other than “WebKit built-in PDF,” that is probably the culprit.
    On my computer, the problem was “AdobePDFViewerNPAPI.plugin”. To remove it, I quit Safari, did a Spotlight search (Command-Option space) for that file name, and then dragged it to the trash. When I restarted Safari, I could print and save PDFs again. You can also manually find the plugins by going to the system “Library”  folder (the one at the root of your hard disk, not in your user folder) and looking in the “Internet Plug-Ins” folder.
    I’m on OS X 10.8.2, running Safari 6.0.2 (8536.26.17).

  • New HD, Now Adobe Acrobat Pro 8.16 Won't Print PDFs to HP2605dn

    Had a HD die. Replaced with new one. All humming along on my OS 10.4.11 G4Powerbook except now newly re-installed Adobe Acrobat Pro 8.16 won't print PDFs to my HP2605dn printer. Adobe Reader 9.1.3 and Preview will print my PDFs so that's a workaround, but would like to get Acrobat Pro back to pre-grey screen of death functionality.

  • Macbook pro recognizes but won't print with hp desk jet 5550. Help!

    macbook pro recognizes but won't print with hp desk jet 5550. Help!

    Hi, I used the Mac setup instructions, not the PC ones.  The printer was automatically recognised in print and scan when I connected it with a USB cable.  I accessed the server's web-based page and followed all the instructions, but still no joy.  Thanks for the tip about posting.  I have just posted in the section you suggested, so let's see what happens.  From a quick scan around the apple forums, lost of other people seem to having precisely the same problem (and not just with HP printers!), but unfortunately, no-one seems to be offering a solution!  And trying to get through to the apple online support is a complete waste of time.  They've been 'not available' for two days now.  Christmas/New Year shutdown, I suppose.  Thanks for all your help, though!

  • I have 1000  photos in an iPhoto Library that won't import into Photos because it says the metadata can't be read.  Yet those JPG files open just fine in iPhoto, GraphicConverter, et al.  What gives?

    I have 1000  photos in an iPhoto Library that won't import into Photos because it says the metadata can't be read.  Yet those JPG files open just fine in iPhoto, GraphicConverter, et al.  Any thoughts?

    It’s part of the basic install of OS X. So unless you deleted it then it’s there in your apps folder. If you have deleted it, it’s on the System Restore disks that came with your Mac. You will be able to extract the installation package using Pacifist.
    Alternatively, if you’re using almost any camera +apart from a Canon+ then the camera card is visible on the desktop and you can drag the movie to the desktop using the Finder and import from there.
    No matter what camera you use, if you pop the card from it into a USB Card Reader then it will be accessible via the Finder. Card Readers are inexpensive and all round a better idea.
    Why use a Card Reader?
    Because it’s safer: Less risk of your images being lost if your camera shuts down during transfer.
    Because it saves the battery on your camera
    Because it saves wear and tear on your camera ports
    Because it’s almost always faster.

  • HP Officejet Pro 8500 A909g Wireless - Can't Clear Print Que - Vista SP 1

    I have an HP Officejet Pro 8500 A909G Wireless printer which is set up wireless through a router.  Used to be able to print to this printer from any computer in the house except now.  I tried to print a document from my HP Pavilion laptop to the printer; it didn't print.  I tried multiple things, didn't work, so tried cancelling the document from the print que.  For 2 days now it has the print que has showed this document as "deleting", pages 6/2, shows date and time of request to cancel print job.  I went into Control Panel, right-clicked on the printer and chose "cancel all documents" and the print que still shows this document as deleting.  No ability to cancel printer job from the physical printer itself.  I've tried restarting the computer to see if it would clear the que; it doesn't.  Read through previous posts and tried several of the suggestions; nothing works.  Can no longer use this laptop to work and print.  HELP!  Vicki

    I have had to delete the printer, search for it again, and re-install it!
