Macbook ip printing not working

I have a printer attached to a wireless print server. I can print to it from my iMac through IP but the same setup does not work on my MacBook.
The only difference is that my iMac is connected directly to the router where my MacBook is connected through wifi.
Here are the CUPS error_log entries:

BTW: This setup was working right up until a few weeks ago. Both Macs are running Lion.
Any advice on how to fix this or what to check?

In a word, no.
Here's the deal, the RIP is called "Production", and is an XP box feeding a CLC 1140. Let's say the IP of the RIP is 1.1.1.1.
All other Macs under Panther are set up like this:
Printer Name: Production
Print Queue: Productionon1.1.1.1
PPD: DocStream1140xxx
My problem is, under Tiger (10.4.5), I can't get the queue name to stay as IP (ie: Productionon1.1.1.1). It keeps defaulting to Productionon_1_1_11 (underscores).
All I want to know is how to get the queue name back to IP scheme and get rid of the underscores.
I've tried every possible combination in printer setup, and in fact, it doesn't even matter what I type in the Queue Name field, it picks up whatever's in the Name Field.
All I know is, this wasn't an issue before the upgrade.
Thanks,
jr

Hello Betty7,
Please let me take a moment to say "Welcome" to the HP Forums.
I hope you enjoy your experience!
I see that you are having an issue with getting the printer reinstalled.
I suggest that we start off by running the HP Print and Scan Doctor. If the Doctor fails, please let me know where it fails as well as any error codes it may generate.
Thank you for your time.

IMessage (Macbook pro) suddenly not working!?

My imessage from my macbook pro is not working! When I send a message, it automatically displays a red exclamation point and the name of the person I am sending it to turns red. When I click on that it tells me that their number is not registered with imessage! I've sent imessages before (today even) and I don't know what happened. I think I may have messed with some preferences because I was trying to change security preferences, but maybe I accidentally clicked something I shouldn't have? I know it is me because I get the same error for every person I try to message. It works from my phone, though.

This could be a complicated problem to solve, as there are many possible causes for it. Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
Before proceeding, test on another network, if possible. That could be a public Wi-Fi hotspot, if your computer is portable, or a cellular network if you have a mobile device that can share its Internet connection. If you find that iMessage works on the other network, the problem is in your network or at your ISP, not in your computer.
Step 1
Check the status of the service. If the service is down, wait tor it to come back up. There may be a localized outage, even if the status indicator is green.
Step 2
Sign out of iMessage on all your Apple devices. Log out and log back in. Try again to sign in.
Step 3
Restart your broadband device and your router, if different. You may have to skip this step if you don't control those devices.
Step 4
From the menu bar, select
 ▹ About This Mac
Below the "OS X" legend in the window that opens, the OS version appears. Click the version line twice to display the serial number. If the number is missing or invalid according to this web form, take the machine to an Apple Store or other authorized service center to have the problem corrected.
Step 5
Take the steps suggested in this support article. If you don't understand some of the steps or can't carry them out, ask for guidance.
Step 6
From the menu bar, select
 ▹ System Preferences ▹ Network
If the preference pane is locked, click the lock icon in the lower left corner and enter your password to unlock it. Then click the Advanced button and select the Proxies tab. If the box marked SOCKS Proxy is checked, uncheck it. You don’t need to change any other settings in the window. Click OK and then Apply. Test.
The result may be that you can't connect to the Internet at all. Revert the change if that happens, or if iMessage still doesn't work. Remember that you must Apply any changes you make in the preference pane before they take effect.
Step 7
Select from the menu bar
 ▹ System Preferences… ▹ Flash Player ▹ Storage
and click
Block all sites from storing information on this computer
Close the preference pane.
Step 8
Make sure you know the ID and password you use with iMessage. Launch the Keychain Access 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 Keychain Access in the icon grid.
Use the search box in the toolbar of the Keychain Access window to find and delete all items with "iMessage" in the name. Log out and log back in.
Step 9
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
If iMessage worked in the guest account, stop here and post your results.
Step 10
Boot in safe mode and log in. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. After testing, reboot as usual (i.e., not in safe mode) and test again.
If iMessage worked in safe mode, but didn't work when you booted out of safe mode, stop here and post your results.
Step 11
Reset the NVRAM.
Step 12
Reinstall OS X.
Step 13
If none of the above steps resolves the issue, make a "Genius" appointment at an Apple Store, or contact Apple Support.

Hi, my MacBook Air is not working anymore if it's not connected with the power cable. It's pretty new so I can't imagine that the battery is dead already. Why can't I use my MacBook Air without the power cable even though I charged it for hours?

The sound on my macbook pro is not working

The sound on my macbook pro is not working. When I increase the sound, the icon appears as if everything is working, but no sound comes from the speakers. Earphones don't work either. I have tried a PRAM reset but at times, this doesn't even work. It's really frustrating having to restart my computer every time I want the sound to work, and even when I do that, theres a 50 50 chance of it working again. It generally happens after my laptop goes to sleep and I wake it up. Has anyone else had this problem and fixed it or even know what caused it?
There are a lot of discussions around the earphone jack but I have checked that. I've tried a PRAM reset which hasn't worked, and my sound output is set to Internal speakers.
HELP!!

Hopefully one of these steps should solve the problem.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure Mute is not enabled.
2. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
3. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

Printer not working following iPad uodate

Printer not working following iPad upgrade

Hi,
Is the printer not mechanically working or are you having a problem with printing wirelessly from your device? Was the upgrade to the ipad software or did you get a new ipad?
Try restarting your apple device - It's a simple fix that sometimes helps re-establish the connection to the printer.
Other things to check would be that there have been no recent changes to the wifi password.

Yuu can try to reactivate your iSight camera by opening up iMessage.. navigate to Preferences/Audio Video,and then click on Camera. IT shoudl be grayed-out if you only have one camera hooked up to your machine. If you have an external camera, then disconnect it from your machine.
