MacBook can't find network printers or servers via Airport Express

My MacBook won't see my Laserjet 6MP (connected thru JetDirect) using either Appletalk (active on Airport but not on Ethernet) or IP Printing (via LDP). I just updated to 10.4.6 and it still doesn't work. I'm using an Airport Express which is connected to an office ethernet network via Belkin Router.
I do get a good internet connection but interestingly enough, when I try to see the other computers on the network, they don't show up in the "Network" window. However, if I type in their IP addresses in the "connect to server" window, they show up just fine. I get the same results on an iBook G3 (which connects to everything properly when I use a hardwire Ethernet instead of Airport).
Any idea what might be going on?

SUCCESS! I just got off the phone with one of the head printer engineers at Hewlett Packard. The basic problem was that BOTH the Belkin router and the Airport Express were supplying IP addresses via DHCP and they were fighting with each other. Using Airport Admin Utitlity, I turned off "Distribute IP Adresses" in the Network Tab. Basically, this turns the Airport Express into a repeater for the Ethernet router.
Now the MacBook is getting it's IP address from the Ethernet router, as is the printer, and everything is fine. All computerS, wired and wireless, can see each other in the network browser and print to all the printers.

Can I play tracks from my iPod via Airport Express on only from my laptop?

I can play tracks from my laptop thorugh my Bose Lifestyle Airport Express. Is there a way to play tracks from my iPod Touch through my Bose system via Airport Express? My Airport Express is set up as a client to my Sky Broadband wireless router.

I set up my laptop to my Bose Lifestyle System via Airport Express. It may be different for MAC but I just downloaded the Airport Express software and followed the on-screen set-up procedure, which includes entering your WI-FI key. I do not have an iPad. You need to select Airport Express in iTunes as your sound media. This is easily switched by an icon in the bottom right corner of the screen. You will need to switch this back if you want to revert to using the laptop speakers.

IMac can't find network printers

We have 4 Macs in the office and a bank of 4 printers all of which have been working great and connecting together for a while with no issues. However in the last few days the iMac can't find 2 of the printers. We tried to reload them through Print and Scan preferences but they didn't appear in the preferences. Checked all the cabling and hub and everything seems OK. Booted the iMac in Safe Mode and it could see them both straight away, rebooted the iMac and again they did not appear in the list, Tried to share one of the printers from a MacPro and it appeared in the list however sometimes it just won't print to it, it seems to print but nothing appears at the printer. Since then we have reinstalled Mavericks, Verified and Repaired Permissions, Verified the HD, reset the PRAM, all to no avail.
Apart from that the iMac prints to the other printers on the network without any problem and connects to the other Macs with no problems as well. We're using 10.9.4 on a 2.7GHz iMac with 8GB of memory. The other Macs can all see and print to all the printers. We are using a wired ethernet connection, not wireless.
Has anyone any suggestions as to the problem as it's becoming really annoying now.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.

Can't find networked printers in mountain lion

Tyring to setup Mountain Lion with a networked printer. Does not show up when trying to add printer. This seems to be happening on any Mountain Lion computer that I setup. (10.8.x) Adding networked printers in Lion worked just fine, but not in Mountain Lion.
Anyone have any ideas?

Printers don't advertise on Windows. The Windows print server can be configured to advertise a printer, but usually you must enter the details of the device to add it.
As for Mac, it sounds like you're talking about multiple network printers as opposed to a single network printer.
Do you know if the printer in question supports Bonjour?
How is this printer connected to the network - wireless or wired?
Can you ping the printer?
Can you connect to its internal web page?
If you use a utility like Bonjour Browser, does this see the printer on the 10.8 Mac?
You may want to give some specific examples instead of a blanket statement.

Can I use multiple printers on the current airport express??

I would like to hook up multiple (3) printers for wireless printing using AirPort Express. Would also entertain AirPort Extreme. The printers are just too far away to make cabling practical and was wondering if the current crop of AirPort devices would support multiple printers through the use of an attached USB hub. The only other thread that seems to discuss this is from 2006. The salesperson at my local AppleStore did not have the info and suggested I come to these forums and ask the community.
I am running a MacBook Pro 17" 233 GHz Core2Duo with MacOSX 10.6.8
The printers I would like to connect are 1 epson Pro7600 wide format, 1 HP DesignJet 1220c and a Brother 1440 laser printer.
Thanks
Phil

Yes....if you use a powered USB hub with its own power supply.
I use a 4 port USB powered hub from Dynex available at Best Buy. Works fine. I am sure that there are many other powered hubs that will work as well.

Where can I find the 'Ethernet ID' of my airport express 2nd?

Where is the 'Ethernet ID of the airport express 2nd? I cannot find it on the box.
Many thanks

The Ethernet ID and AirPort ID(s) can be located using AirPort Utility.
If you can let us know which version of AirPort Utility you are using, we can give you specific steps to locate the Ethernet ID.

Can i share files between two macs via airport express?

hi. we have an imac and a macbook connected to the internet with airport express. all is well with that, but i'd like to be able to share files between the two computers. it seems like i should be able to, but i can't figure out how. can someone help?
thanks.

Hello smw380. Welcome to the Apple Discussions!
Yes. You just need to enable "Personal File Sharing" on both Macs.
o System Preferences > Sharing > Services tab
o Personal File Sharing: On (checked)

MacBook can't find network computers until accessed remotely

On my home Airport network, after I restart my MacBook it can see the other networked computers (i.e. they are listed in the network window) but I can't access them to read files or screen share. If I click on one of their icons nothing happens and then after a while a message comes up saying the other computer doesn't exist or is offline. Then if I go to one of those computers and access the MacBook, which I can do with no trouble, then go back to the MacBook I can now access all the other networked computers from the MacBook. The connectivity is available until I restart the MacBook.
This never happened before I got Snow Leopard, but I'm not sure that it started immediately with SL, it could have been some time afterward, so I don't know that SL is solely to blame. I've added no other system software or hardware to any of my computers.
Is there some setting I'm not using or what?

I'm kind of in a similar boat. I have three machines an iMac, MacBook Air, and a MacBook all with their own MobileMe accounts so "back to my Mac" is enabled. The strange thing is whether I'm on my home network or trying to access from the office to my home the computers show up in the sidebar but if I try to access file sharing no go. Now the strange things is screen sharing works fine so if I open that and access the file sharing preferences on the machine I want to access and toggle it off and back on bingo I can connect. I don't get it at all. I have been doing this for some time. A bit of a hassle but it works. I wish though I could figure out how to get file sharing to work on a regular basis.

ITunes 8: I can no longer connect to remote speakers via Airport Express

Cannot connect to my remote speakers, worked before iTunes 8"
I have restarted the computer, iTunes, QT 7.5.5, run disk utility
I get the following error code (-3256) Apple KB research says:
AirTunes: Error -3256 when streaming to multiple AirPort Express units  You may see this message: An error occurred while connecting to the remote speaker speaker_name . An unknown error occurred (- 3256 ).This occurs with iTunes 6.0.2 or later.SolutionIf you use a third-party firewall or router, make sure that it is configured to permit UDP traffic. http://docs.info.apple.com/article.html?artnum=303157
I followed the KB link, tried KB solution, then I sent this off to Apple.
"Mac G5 2.0 Ghz, OS 10.5.4 just installed iTunes 8, one (1) Airport Express connected to remote speakers. Firewall under Sharing in System preferences does not offer firewall access. Firewall is under Security but "Advanced" is grayed out.
Cannot connect to my remote speakers, worked before iTunes 8"
I have restarted the computer, iTunes, QT 7.5.5, run disk utility, unplugged the airport express.
My G4 PowerBook running an earlier version of iTunes connects without problem.

I just got off a 30+ minute phone call with an Apple Support rep about this. I'm getting error -3256. The rep was patient and tried hard to solve the problem, but was basically clueless. I have a case number and was encouraged to call back tomorrow to speak with a product support specialist.
This stinks. AirTunes is my primary way of playing music from my computer. With no obvious way of rolling back to iTunes 7, this is a big deal.

Time Machine: Macbook can't find external network hdd

Hi,
I'm want to backup BOTH my Macbook Pro (Retina) and my Mac Mini (Late 2012) to an external hard drive (Western Digital My Passport) USB-connected to the Mac Mini.
Alas, this doesn't work. I can't figure out why. The Mac mini finds the disk with no problems and can backup to it via Time Machine. But when I open Time Machine on the Macbook Pro, it can only backup to the Mac Mini. That's the only location it finds; it can't find the external disk.
I've enabled file sharing and shared the external disk, and set it to be available for guests to read/write. I've even bought OS X Server and used the same configuration there (although it seems to sync it from the Mountain Lion config anyway). Still nothing, the macbook can't find the external disk, only the Mac mini itself.
What could be the problem? All guides I find is about backing up to the Mac Mini over wifi. I don't want the backups on the Mini, but on the external disk connected to it.
Thanks!

Nope, but I see the Mac Mini as a network volume. And from it I can access the external drive (and everything else on the Mini).
So I can only see the "first step" (the Mini) but not the second (the external drive). And from Time Machine I can't specify where to save my backups, OS X will create that automatically.

I am having trouble connecting to wifi network via airport express on my windows xp pc, but I know it is working because I can connect on my macbook, does anyone know what the problem is?

Tell us more about the problem, I can think up 100&1 different reasons, but don't have time to go through all the possibilities. So.. what happens?

Can't find certain servers connecting via Airport Express

For the last couple of weeks I've been intermittantly unable to access certain websites (time.com / nytimes.com) when connected to the Net via Airport Express. Sometimes these pages come up, more often then not, they don't. I have no problem receiving email or accessing other sites. Also, I always loose my connection when streaming news stories from NPR. However, I have no such problem when connected directly via ethernet. Thus, it seems to be some glitch with airport express. Does this make sense to anyone?

You don't describe what happens when you try to print.
Does the IP address your computer is granted in both configurations match in the first three elements (such as 10.0.1.5 and 10.0.1.7)? If not, then your AirPort Express unit is creating a new "subnet", which can cause problems when your computer tries to communicate with the printer.
Try adding the printer in the "Print & Fax" panel of System Preferences by choosing the "IP" option and entering the IP address of the printer.

My iPhone 4 can not find network after updating to 7.0.6

my iPhone 4 can`t find network after updating to 7.0.6. i`ve reinstalled system, but nothing`s really changed.

iPhone 4S: I have the same problem. After updating to iOS 7, wifi worked for some time, and then it stopped working. I can't even enable wifi. I just updated to iOS 7.0.2 and it didn't help at all.

Welcome to the WD Community.
1) I assume I can just hook the unit up via USB to my Mac and use iPartiion to reformat the drives, assuming each of the 4T drives will be seen by iPartition as a separate drive. That much seems straighforward.
Yes, and in case you ipartition dont see the unit properly, you can use the disk utilities on your Mac and you will be able to reformat the unit to make it compatible with your system.
2) Is my next step to reinstall the WD software and how do I do that? I've downloaded the Drive Utilities and Securities install apps - I assume I just run these with the drive still connected and that's all I need to do?
Yes, just run the applications.
3) What about the firmware update for Mac - when should I run that??
Normally, firmware updates are released to fix any issues that you might encounter on the drive. the latest one was released on 9/24/2014 and it fixed an issue with the drive dropping off of the list after system wakes up from standby mode.
5) And what about the "My Book Live Duo Setup" app for Mac - is that for a completely different model? What's the difference between "My Book Live Duo" and "My Book Duo"? It's these little things that I find so confusing.
Those are different units. The MBL Duo is a NAS (Network attached system) and the My Book Duo is a DAS (Direct attached system)
6) Lastly, when I have all the software installed, is that when I follow the procedure described in the Knowledge Base article ID 5724, "How to install a My Book Live or My Book Live Duo on Windows (8, 7, Vista, or XP) or Mac OSX for the first time"? Or is that procedure only for "My Book Live Duo" but not for "My Book Duo"??
That procedure is for the network units, not for your drive.
