I can't restablish wifi connection between an C4580 and a Macbook Pro Tosemite 10.10.1

The printer worked both with USB or WiFi till I must change my router. The setup program contained in the instalation disk broke in the final step so I'm unable to configure the wifi. 
The set print and scan, Driver version is 5.0.4.
What can I do?

Hi @Xoan,
Welcome to the HP Forums!
I believe the issues you're running into are because your C4580 doesn't have an HP software package for OS X 10.10, so to reconfigure the wireless, you will have to take a slightly different approach
I'd recommend that you follow the steps in this Re: Photosmart C4780 post that I did earlier this year and those steps should help. To restore the network defaults please go to page 19 of your printer's User Guide and it will explain.
Let me know how things go and if you're able to get things working wirelessly!
Happy Holidays!

  • How can I synch Mail application between an iMac and a Macbook Pro

    I want to be able to go back and forth between my iMac and my Macbook Pro using Mail application.
    I don't want to set up two completely separate accounts.
    Has anyone had to do this and if so, how do I do it?
    Thanks for your help

  • Different wi-fi speed connection between my iMac and my Macbook Pro (both placed side by side)

    I have purchased my iMac and my macbook pro at the same time and now I am facing something which I consider weird. The wi-fi connection speed in my iMac is fine but the wi-fi speed connection on my macbook pro is awful. It works as fine as the iMac if I connect it to a ethernet cable. I have put my macbook pro side by side with my iMac to try it and for my surprise, my macbook pro wi-fi speed connection was still lousy whilst the wi-fi speed connection from my iMac was nice... Does anyone face the same issue?

    Non Apple router? Try restarting the router.
    If you are using an Apple AirPort base station, try a different channel on the MacBook Pro.
    Open AirPort Utility located in Applications > Utilities
    Click on the base station icon then click Edit the select the Wireless tab then click Wireless Options.
    Cick the first Channel pop up menu, select Automatic
    Click the second Channel pop up menu, select Automatic
    Cick Save.
    Give AirPort a minute to reset.
    If automatic does not help, try a numbered channel from the pop up menu.

  • Best connection between new iMac and firewire MacBook Pro

    Hi I'm running a MBP with Firewire, USB (2?) and Ethernet ports. I am soon to take delivery of my shiny new iMac with Thunderbolt, USB 3 and Ethernet ports. What please would be the fastest connection I can establish between the two machines? Thanks, M

    Ethernet is your fastest choice - FW800, to be precise.
    To transfer from the MBP to the iMac use Target Disk Mode. Boot the MBP into TDM, boot the iMac normally and preferably for the first time. This will put you into the Setup Assistant and let you migrate data from the MBP - Home folder, third-party applications with support files, and system preferences.
    If you prefer not to do a migration then you can also simply transfer selected items using drag and drop.
    A Basic Guide for Migrating to Intel-Macs
    The Knowledgebase article Intel-based Mac: Some migrated applications may need to be updated refers to methods of dealing with migrating from PowerPC chips to Intel with the Migration Assistant safely. The authors of this tip have not had a chance to verify this works in all instances, or that it avoids the 10.6.1 and earlier Guest Account bug that caused account information to get deleted upon use of the Migration/Setup Assistant. However, a well backed up source that includes at least two backups of all the data that are not connected to your machine will help you avoid potential issues, should they arise. In event it does not work, follow the steps below.
    If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate.  Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
    Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
      1. Classic Environment, and subsequently any Mac OS 9 or earlier applications
      2. Screensavers written for the PowerPC System Preference add-ons
      3. All Unsanity Haxies Browser and other plug-ins
      4. Contextual Menu Items
      5. Applications which specifically require the PowerPC G5 Kernel extensions
      6. Java applications with JNI (PowerPC) libraries
    See also What Can Be Translated by Rosetta.
    In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
    If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
    If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
    The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
    Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior, TechTool Pro , SuperDuper , and Drive Genius  work properly on Intel-Macs with Leopard.  The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.  Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
    Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.
    Additional links that will be helpful to new Intel-Mac users:
      1. Intel In Macs
      2. Apple Guide to Universal Applications
      3. MacInTouch List of Compatible Universal Binaries
      4. MacInTouch List of Rosetta Compatible Applications

      6. Transferring data with Setup Assistant - Migration Assistant FAQ
      7. OS X Lion: How to use Migration Assistant to transfer files from another Mac
    Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs.  The initial section below discusses Target Disk Mode.  It is then followed by a section which discusses networking with Macs that lack Firewire.
    If both computers support the use of Firewire then you can use the following instructions:
      1. Repair the hard drive and permissions using Disk Utility.
      2. Backup your data.  This is vitally important in case you make a mistake
          or there's some other problem.
      3. Connect a Firewire cable between your old Mac and your new Intel Mac.
      4. Startup your old Mac in Transferring files between two computers using FireWire.
      5. Startup your new Mac for the first time, go through the setup and
           registration screens, but do NOT migrate data over. Get to your
           desktop on the new Mac without migrating any new data over.
    If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
    1. Set up a local home network: Creating a small Ethernet Network.
    2. If you have a MacBook Air or Late 2008 MacBook see the following:
      a. MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch,
          Late 2008) - What to do if migration is unsuccessful;
      b. MacBook Air - Migration Tips and Tricks;
      c. MacBook Air - Remote Disc, Migration, or Remote Install Mac OS X and
          wireless 802.11n networks.
    Copy the following items from your old Mac to the new Mac:
    In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
    In your /Home/Library/ folder:
    /Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)
    Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
    /Home/Library/Keychains (copy the whole folder) /Home/Library/Mail (copy the whole folder) /Home/Library/Preferences/ (copy the whole folder) /Home /Library/Calendars (copy the whole folder) /Home /Library/iTunes (copy the whole folder) /Home /Library/Safari (copy the whole folder)
    If you want cookies:
    /Home/Library/Cookies/Cookies.plist /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
    For Entourage users:
    Entourage is in /Home/Documents/Microsoft User Data Also in /Home/Library/Preferences/Microsoft.
    Credit goes to Macjack for this information.
    If you need to transfer data for other applications please ask the vendor or ask in the  Discussions where specific applications store their data.
    5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

  • I'm debating between the 15" and 17" MacBook Pro. Any suggestions?

    I'm debating between the 15" and 17" MacBook Pro. Any suggestions?

    It appears that is up to me to pick up the mantel and defend the 17" MBP (As an owner of two of them).
    Yes it is heavier that the 15" model, and by an enormous 16 ounces!  Not a day goes by that I contemplate acquiring a fork lift to move that obese beast.
    Oh that 17' screen, the Cinemascope of laptops.  The extra space adds to the efficiency of use and has an edge when viewing DVDs or when converted to a HD TV.  (I will grudgingly acknowledge eww's recommendation to check out the high resolution properties prior to purchase)
    It has a express card slot that allows for eSata connections (No mere SD card slot).  Most useful when one has to transfer large file to and from external drives.  In addition it has three USB ports rather than just two (I probably should not let it be known that I have yet to use all of the simultaneously).
    Off my soap box.
    Is it worth an extra $300?  That becomes an individual choice.   Either way the final decision is going to be a good one.
    Ciao.

  • Can't establish wireless connection between the printer and computer.

    I recently upgraded my wireless to an Apple AirPort Time Capsule. I'm able to set up the printer via USB cable. And I'm able to set up the printer on the network via the Airport WPA utility. However I cannot establish a wireless connection between the computer and the printer. When I go to the printers window  in my system prefereces, there is no wireless printer available to add in the "available printers" menu. Only the USB version printer is listed and of course when I disconnect the USB cable it shows as offline.I've tried all the fixes on HP's support pages. I've tried reinstalling the printer on both the router and the computer numerous times. The only thing I haven't done is reinstall the printer using the "Install Wizard" software that is supposed to come with the printer - (mine never came with it in the first place and of course HP doesn't have it available for download). And when I reset the printer to factory settings, then connect it to the computer via the USB, there is no installation software that pops up. Cant even find the **bleep** thing in "Finder". (I'm assuming that it should show up as some sort of external device.) I've checked to make sure both computer and printer are on the same network. (sometimes my computer will grab a connection with the next nearest network.) I've checked all the settings for the printer via the HTML configuration utility. I've even updated my Macbook software and restarted it multiple times. Note: the printer actually worked for a bit when I first switched routers, but the printer's wireless function went offline several times and then quit  altogether. Really frustrated that I bought another HP product thinking this time things would be different. HP is no help unless you want to pay $$ for a phone call. I'm about ready to take this thing out in the desert to use for target practice and never buy another HP product ever again.

    Hi , I saw your post regarding the problems you are having with your LaserJet Pro P1102w Printer not showing on your Macintosh computer. I may have found some resources for you. 
    I have a few questions for you, so I can offer some additional assistance:Before you upgraded to the Apple AirPort Time Capsule, was the printer working wirelessly without any issues?
    When you say; 'I reset the printer to factory settings', how where you trying to do this? 
    I found some instructions from this post: How do I reset my Laserjet p1102w to its defaults, copied here for you:
    To restore the printer back to factory settings, turn the printer off, hold down the wireless button and the cancel button (x button) then turn the printer back on and don't release the two buttons until the printer stops making noise. (When they say turn the printer off, I think they mean unplug the power cable.)
    "I've checked to make sure both computer and printer are on the same network."  Do you know if you are able to access the printers Embedded Web Server (EWS)?To access the EWS - Make sure that the Ready light () is on and that the printer is idle and silent.Press and hold the Cancel button (), and release it when the Ready light () begins blinking.The configuration page prints.Type the IP address or host name of the product in the address field of a supported Web browser, and then press Enter on your keyboardLet me know if this page loads 
    To answer a few more items you have listed:... When I go to the printers window in my system preferences, there is no wireless printer available to add in the "available printers" menu.This could be an issue with your print system, I recommend resetting the printing system and then Repair Disk Permissions - after that try to add the printer again.
    ... the "Install Wizard" software that is supposed to come with the printer - (mine never came with it in the first place and of course HP doesn't have it available for download)HP provides their software/drivers to Apple to be released through your Apple software updates. You can review this document on how to Install a Mac Printer Driver Using Apple Software Update. Which leads into your next point...
    ... there is no installation software that pops upWhen you connect the USB cable your mac may still recognize the printer software as being already installed - check for apple updatesOn the Mac, click the Apple menu (), and then click Software Update, or click About this Mac, and then click Software Update. A list of available updates displays.
    ... Not seeing the printer in "Finder" From what I understand most printers will not show in Finder unless you install a memory card into a supported port on certain printer models, only then will it read it like an external device. A few more things you can check are that the new settings in the Apple AirPort Time Capsule are setup to allow the printer to communicate. There are several of these settings listed in this document; Tips and Workarounds for Common Wireless Network Printer Issues.  HP regularly releases firmware updates that may also correct the problem you are experiencing. You can click on this link to Getting Printer Updates for HP LaserJet Pro P1102w Printer.  I did find 2 more documents that may offer some additional information as well;HP LaserJet Pro P1102w Printer - Connecting the Printer After Changing Your Wireless NetworkAn 'Unable to Find Printer' Error Displays for the HP LaserJet Pro P1102w Printer  Please let me know if any of these steps resolved your issue, or the details of what happened.  I look forward to hearing from you, hopefully with good news!   Thanks, 

  • How can i make a connection between an application and a database over net

    dear sir
    how can i make connection between an appliction and a database over internet while the client side appliction is behind proxy and firewall
    for example how the live update of norton antivirus makes connection to the data server to make comparetions and get new virus definitions
    does that depend on sockets technology ?
    what references can guide me to the solution please?

    The ability to do so depends entirely on the JDBC driver implementation having some proxy method. It needs to recognize the HTTP or SOCKS proxy and use them to connect, and the firewall and proxy need to allow those specific port connections.
    To the best of my knowledge, all of these update utilities, e.g. live update for Netscape, Norton, etc., do not connect directly to the database. As it is, no sane security person would allow a database to be exposed to the Net. Rather, they connect using HTTP or HTTPS, which normally traverses firewalls just fine, to connect to a Web or application server on the far end. That application server then parses the request and retrieves whatever it needs to from the database.
    In other words, you cannot have a 2-tier client/server application. You need a 3-tier application:
    your client -> Web/app server -> database
    where the connection from your client to the Web/app server is over http or https through the firewall and proxies.
    Hope this helps.

  • Can't make a connection between my tv and laptop

    I can make a connection between my laptop and tv as far as being able to view the picture I have as my wallpaper on the tv, but that is all.  If I change the wallpaper picture on my laptop it will change on the tv also, but again that is all I can do. That is far as I can get.  Just a picture, no icons, no nothing.  I have connected using a 15 pin cable on both ends.  I have windows xp.  There must be a setting in control panel, display or somewhere but I cannot find it.
    HELP

    Thanks, but that didn't work.  Nothing happened.  This time however I completely turned off the tv and computer.  When I booted up the tv screen showed my password sign in screen.  I entered my pass word,  The screen momentarily showed my complete desktop, both  wallpaper and icons but after about a second or two it blinked and then showed only my wallpaper as before.  Puzzling.  There has to be an answer somewhere.
    Thanks for your help.

  • Syncing OS X between an iMac and a Macbook Pro

    Hi all. Is there any way to seamlessly sync an OS X installation across an iMac and a Macbook Pro, i.e. application installations, application preferences, data, etc?
    If you need more background info: My 15" 2.8Ghz Core 2 Duo, 4GB RAM Unibody Macbook Pro is beach-balling a lot at the moment, and it looks like I need to face up to the fact that I'm going to need more power to keep up with my workflow. I'm tempted by a 27" iMac, but I'm pretty hooked on the Macbook Pro portability in combination with a Cinema Display. It's vital that I can easily grab my laptop from the desk and that when I open it on a train or hot desking that my workflow won't be interrupted by not having the same apps, browser bookmarks, etc. Is there any way to keep things sync'd, or am I better off upgrading my Macbook Pro to 8gb RAM and an SSD?

    There isn't one tool that syncs the computers however there are numerous solutions to doing some syncing. I don't believe there is a sync tool for applications though, however you can sync quite a bit. What I use are two solutions, I use Drop Box for files I want synced. This is really simple you simply store the files in your Drop Box folder and it will sync between the devices you have specified. You can get 2GB of storage for free and pay for additional storage.
    Next I use SyncTogether to sync:
    Bookmarks
    Calendars
    Contacts
    Dashboard Widgets
    Entourage Notes
    Mail Accounts
    Mail settings
    Notes
    Preferences
    You can find both solutions using Google.

  • Can't establish ftp connection between a Xserve and a PB

    We want to use a Xserve (Mac OS X Server 10.4.8) to provide webhosting, but experience problems in establishing ftp connections using a PowerBook (Mac OS X 10.4.8).
    On a WinXP-based notebook using the same Internet connection, anything works fine, just not on my PowerBook.
    This is what happens when trying to establish a ftp connection (via terminal):
    I type: ftp [email protected]
    Returns:
    220 star1.local FTP server ready.
    331 Password required for user.
    I provide the password, anything looks fine, get this output:
    230 User starenterprise logged in.
    Remote system type is UNIX.
    Using binary mode to transfer files.
    ftp>
    Okay, now I want to see what files are in the directory using "dir" command ("ls" brings same result). This output is shown:
    502 'EPSV': command not understood.
    227 Entering Passive Mode (132,78,123,92,42,115)
    Now I can either press CTRL+C to escape or when waiting around one minute, then it states this:
    421 Service not available, remote server timed out. Connection closed
    On a ftp client software like CuteFTP Mac it shows "Can't open data connection" instead of, but result is the same.
    I read through some articles I found here, but nothing compared to my problem. Please help.
    I should mention one thing Apple's support told me: Since I have the same username and UID on my PowerBook as well as on the xServe, it could bring problems. However I have then added a new user to my PowerBook, result is the same. And Apple's support left helpless so far.

    You said: "Not really answered, the problem persists and I now go on and let
    Apple work on it again"
    As a native English speaker, I must say (and doubt any would disagree) that
    your statement implied: "No one here has actually helped me fix this problem,
    and now I'm waiting for Apple to fix it"
    Please take care to the word "again" I used; this implies that Apple has tried to solve the issue before but failed (in fact, they stated to call me back, but this is weeks ago) and so I posted this here at the discussions.
    Unfortunately I only have access to the "free" support (well, free is not the right word when paying 12 cents per minute for the phone call).
    And this means (at least I can speak for the German part of Apple) that operators on the phone look at their knowledgebase and sending articles by e-mail; questions going deeper are resulting in a "we call you back" answer. Sometimes they phone back, sometimes not. Sometimes they are helpful, sometimes (or should I say "in most cases") they just give hints or ask me to investing a nice amount into premium support.
    Don't misunderstand me in the direction that I demand assistance from this forum - I'm more than gradeful if I get help (and rewarded this always with giving points), it has saved me several times (many, many, many times) for doing time consuming investigations and making trial-and-error experiences by myself. If I cannot get more assistance, well I have to look elsewhere and so be a bit impertinent to Apple's support. Perhaps it helps
    You are right, FTP itself works correctly. It even works fine on the WinXP notebook residing at the same LAN as my PB. Therefore the issue is at the PB's firewall very likely (or a strange relationship between two firewalls which seems not to affect WinXP).
    But as you indicate, it makes no sense to lower down security just for doing ftp, especially since SSH works well. However since I have no problems doing ftp sessions with other servers, I would be eager to find the reason why it refuses in this case, even this just means feeding my curiosity
    So if I come to new insights, I post them here. But I feel that I'll really need your wishes for luck to solve this problem Let's see...

  • How can I have Facetime callers distinguish between my Ipad and my MacBook Pro?

    I'm wondering how does one set things up so that a Facetime caller can distinguish between calling me on my iPad versus calling me on my MacBook Pro? I have family calling me and it is popping up on the MacBook when, ideally, the call would come through to my Ipad when I'm traveling?

    Hello Mac_ThePI,
    In FaceTime's preferences, you can choose what Apple IDs and/or phone numbers you can be reached at. You might choose to make the phone number or certain Apple IDs the only checked option(s) on your iPad, and others on your Mac.

  • The lastest iTunes upgrade broke my wireless syncing between my iPhone and my Macbook Pro

    iTunes was actually working before the latest update. Now I cannot wirelessly sync my phone to either my MacBook Pro or my PC.

    Hi, AppleJR.  
    Thank you for visiting Apple Support Communities.  
    I understand that you are unable to sync via Wi-Fi after updating iTunes. I would start with going through the troubleshooting steps outlined below. 
    Quit and reopen iTunes and restart your iOS device
    Quit and reopen iTunes on your computer. Then, restart your iOS device.Restart your network router
    Restart your home network router using the manufacturer's instructions. You may need to disconnect the power cord for 30 seconds or more.
    Note: During this time, Internet services, such as a VoIP-based phone, won't work, and you may need to reset additional network devices.Check your network connection
    Make sure that your Wi-Fi network has an active Internet connection.
    Make sure that you connect your iOS devices and computer to the same network over Wi-Fi.
    Check for network configuration changes that may interfere with syncing:
    VPN configurations
    Extending the Wi-Fi network through multiple wireless access points or routers
    Guest networks or other security configurations that limit access between devices
    Routers that configure different networks for different frequencies such as 2.4 GHz and 5.0 GHz
    Connecting the computer over Ethernet
    Wake up your computer and open iTunes. If your computer is asleep or iTunes isn't open, the device may not sync.
    Update your router. If you're using an AirPort or AirPort Time Capsule, you can learn more about firmware updates. If you're using a router from another manufacturer, contact the manufacturer to ask about available updates.
    Check for network interference
    If you see performance issues when you sync over Wi-Fi, something may be causing wireless interference:
    Microwave ovens
    Cordless phones
    Physical barriers, such as metal walls or distance between your computer, base station, and iOS device
    Try the following to reduce network interference:
    Move your iOS device and computer closer to the Wi-Fi router or base station.
    Check for sources of potential interference.
    Remove your iOS device from any case, stand, or attachment.
    Open Safari and try to load a webpage.
    Check firewall settings
    If you enabled a firewall on your router or computer, make sure that your computer and iOS device can communicate.
    Follow these steps to use the built-in firewall option with iTunes on your Mac.
    For third-party firewalls and security software, see the developer or manufacturer for assistance.
    Mac computers use port 123 to set the date and time automatically. Incorrect date and time on a computer or iOS device can cause connection issues. If you don't know if your router has a firewall or if the required ports are open, follow these steps:
    Enable Wi-Fi syncing for additional iOS devices on your network to see if they have the same issue. (See the previous steps to enable Wi-Fi syncing for additional devices.)
    Test your device on a different network. If the device works on another network, the issue may be your router or network configuration. Contact your router manufacturer or Internet service provider for additional troubleshooting.
    If you use another security or firewall software on your computer or router, you can troubleshoot security software issues, contact the manufacturer, or check the documentation to learn how to open TCP ports 123 and 3689 as well as UDP ports 123 and 5353.
