Unable to load HP 8600 printer driver on laptop
Hi Folks,
Just installed a new HP Officejet 8600 printer into my home network. The network consists of 4 PC’s, two desktops and two laptops…all are running XP SP3 with the latest updates. The HP printer and one of the desktops are connected by Ethernet to a wireless router. The other desktop and both laptops are connected wirelessly via 802.11. Installation of the printer driver was successful with both desktops and one of the laptops. The other laptop, a Dell Latitude D520, fails on the final step of the installation process, after selecting the printer name following its detection on the network. Avast! Internet Security and Malwarebytes run on all the machines and are disabled, along with Windows firewall, during the install process. The following dialog is displayed:
“Unsuccessful Network Installation – The printer was unable to be installed over the network.”
No other error information is provided. I’ve tried installing from the product CD (which is up to date) as well as the driver software downloaded from the HP support site, rebooting multiple times. I also downloaded the recommended HP troubleshooting tool (HP Installation Failure – Unknown Device) and ran through the process a couple of times without success. All of the machines, including the D520 laptop, can see each other as well as the HP printer. There are no network issues I’m aware of.
I’ve exhausted what little expertise I have in this area. If anyone out there can think of a possible solution or provide some suggestions, I’d sure appreciate it. Thanks much.
Hello marconi10. Welcome to the HP Forums. I understand you are unable to install your printer on one computer, over a wireless connection. I'm going to suggest a very simple workaround, which if it works, will remove any complicated troubleshooting that would be necessary:
Please try installing the printer with a USB connection. If this does not work, you know that there is an issue occurring with the computer.
If this does work, the printer will be successfully installed. At that point, you can change the connection type from USB to wireless. For more information on how to do this, please reference this HP document: Convert from a USB connected printer to wireless
If the printer will still not connect wireless, this will point out a computer issue. For additional information and troubleshooting, relating to the inability of installing the printer over a wireless network, please reference this HP document: 'Unable to Find Printer' Error Message Displays on the Computer During Wireless Network Installation
Please respond with the results of your troubleshooting. I'm only here to help!

Unable to load Canon MP160 printer driver
I've had the hardest time using my Canon MP160 printer on my iMac (Mac OS 10.5). In fact, I'm not able to print at all.
I have the printer connected via USB. It always has been. However, it only stopped working recently.
I downloaded the drivers for the printer and scanner from Canon's web site. However, when I attempt to load the printer driver, the "Installing Canon IJ Printer Driver" window appears. It gets to the "Finishing Installation" part in the process. But it "hangs" at some point and does not complete. I've tried it twice. It hung at two different points in the process. I tried letting it run overnight. That was no good.
I've also looked for the "Printer Setup Utility" and can't seem to find that anyplace. I'm wondering why I can't find that.
If anybody could help me solve this, I'd be so thankful.Hello marconi10. Welcome to the HP Forums. I understand you are unable to install your printer on one computer, over a wireless connection.

Unable to load LabVIEW RT from drive
Trying to boot RT on PXI-8187 controller with original setup, what ever RT boot selection is used either hardware switch or BIOS RT boot option, the terminal will show the following:
Unable to load LabVIEW RT from drive!
Booting safe mode from ROM...
mount: Mounting /dev/Ma1 on /home/ftp/c failed: Invalid argument
Entering safe mode.
IP address is: 0.0.0.0
Of course after that you can't do any thing to configure the RT target from the MAX on the host computer.
Please Help.Hi,
I used the recovery CD to change the file system to NTFS, it took a while and it installed windows XP from scratch differently from FirstWare that ghosts it (I think). And it didn't install any NI stuff what so ever.
At the end I got the same result as with using the remote system format disk option.
i.e. The RT controller boots in safe mode displaying the previous message without the mount error but this time I can configure the IP address.
Still I can't install software to it, I get the list of features to install, I select them and press next, then I get a dialog saying:
Cannot process install because other dependencies are required:
LabVIEW RT 1.0.1
LabVIEW RT 6.0.1
LabVIEW RT 6.1.0
LabVIEW RT 7.0.0
LabVIEW RT 7.1
Is this a host or RT Controller issue now?
What's next? Thanks for the help -
Unable to load HP LaserJet p1606DN driver in Broker
I am trying to load up a HP p1606DN driver into my broker. The load process fails.
Other drivers load fine. The load fails if I try to load the driver from disk, or if I try to pull it from my PC.
The error message happens so fast I can not read it. It happens right away, right after I select the printer.
The driver is for Windows 7 X64. The broker is on Netware.
Any ideas?
Thanks

Unable to load mySql Driver in Java class invoked using bpelx:exec
Hi ,
I am trying to connect to mysql database in my java class.when i run this class in Jdeveloper it loads the driver without any problem.I can chk the log in the Jdev messages area.Now I am invoking this class from the BPEL process through <bpelx activity.But when i run my BPEL process it throws runtime exception "classNotFoundException:unable to load com.mysql.jdbc.Driver".I have set the project properties ->libraries to the class path of the mysql jar file as well.
Now if i try to connect with the Oracle driver then it is working fine.
I know this is a classpath issue.Can anyone tell me if there are some other settings to make it work fine.
the java code :
System.out.println("in getConnection method");
Class.forName("com.mysql.jdbc.Driver").newInstance();
System.out.println("loaded Driver :");
String url="jdbc:mysql://ntlv014:3306/wx";
_jdbcConnection = DriverManager.getConnection(url,"development","ber1nger");
System.out.println("Got Connection :"+_jdbcConnection.isClosed());I think you have 2 options..
either put the jar for the mysql in the classpath on the server...or try something like this :
http://forum.java.sun.com/thread.jspa?forumID=17&threadID=633158
try to put the jar of the mysql into the suitecase of the bpel.

I had to change my hrowser to Firefox because Internet Explorer 9 doesn't work with my ancestry.com program. I can't uninstall Internet Explorer 9. I got Firefox 4 and it didn't work either. I started having problems with my printer working at all then. l was told to go to Firefox 3.x. I looked and there is no 3.x it is 3.5 or 3.6. I downloaded 3.6. Now I keep getting a alignment page and end up having to shut off my printer. I'm using way too much ink. I'm almost out with no hope of getting more ink until I get paid. I can't find anyplace that says to update a driver or that I need a plug-in or what might be I've done everything I know to do.wrong. It has new port cables. Do you have any idea what could be wrong? Do I need to uninstall the printer and reinstall it again? daisy
I just figured out the print quality issue for my wife with her new iMac and new printer.
She replaced both at once and she couldn't understand why her Artisan 730 was lower quality then her Epson R280 when they had the same specs.
Turns out the newer printer had the option to connect via wifi which we used during setup.
The driver options are completely different depending on how you connect.
Once I connected via USB the correct options were available and the print quality was better.
Looking at the R2400 it dies not have wifi, but while researching the problem for my wife someone esle was having an issue updating to the latest printer driver.
If you go into the print utility from the Printer and Scanner system preference and under the general tab you should have driver 5.5.
One user had to delete the old printer driver before Software Update loaded the newer printer driver.
https://discussions.apple.com/message/15947486#15947486
On my MacBook Pro (w Snow Leopard) I always had to reconnect my wifi at home when it woke up. I upgraded my router from an old Netgear to a newer N D-Link and stopped having to do that.
I would be surprised you would have that problem with an Airport Extreme, you might check to see if there is a firmware update for it. -
Unable to load HP printer driver-Error message!
Hi,
Just wondering if anyone can be of any assistance.
I recently purchased a HP Photosmart 2575 all-in-one printer and installed the necessary software, which said it was successfully installed. However, whenever I boot up the G3 I keep getting the following message 'Unable to load the printer drive, open the applications Get Info dialog and increase the preferred memory size. If this does not help try quitting all other applications or reinstalling the printer software.'
After clicking ok on this message about four times the message goes and I am able to print fine. Just wondering why this is happening. I have increased the memory allocation and also turnt on the virtual memory to see if this makes any difference, but all to no avail. I have also uninstalled and then reinstalled the software to see if this makes a difference, but that didn't help either.
Any help would be greatly appreciated.
Thanks in advance
PS: The printer is connected via ethernet on my router to enable me to print from another machineUse Techtool Lite or Trash*Desktop (TD may delete Finder comments )to rebuild your desktop w/extensions off. Does a better job than manually & you avoid all the finger gymnatics. You just have to hold down the shift key to shut off extensions.
Restart to turn the extensions back on again.
If you want to rebuild manually, see KB article http://docs.info.apple.com/article.html?artnum=10182 Rebuilding Desktop File and Icon Recovery. -
Unable to load icm printer profiles in Lightroom 5
I am unable to access correctly loaded RGB printer profiles in Lightroom 5.
In the print module when color management profile "Other" is selected no loaded profiles appear; and Lightroom usually freezes.
Using Photoshop v6 on same computer I can access all loaded printer profiles. I have reloaded LR5.
Does anyone have a solution or work-around for this problem?The "Include Display Profiles" checkbox is at the bottom of the list that comes up if you click "Other..." in the Lightroom Print Job panel. If this is the point where Lightroom freezes you won't get to it of course. So then the question is what prevents Lightroom from loading that list? Maybe someone else has suggestions, so hang on for a while.
Anyway, whatever the extension, the point is that the profile in question has to be the correct one for that particular printer/paper/ink combination. Apologies if this is stating the obvious, but you don't really have a choice between several, you just pick the right one. They install with the printer driver and are named for instance "Epson <model> Premium Semigloss" and so on, different profiles for different paper types.
Or you can make your own profiles. I believe the ColorMunki, for one, lets you create printer profiles as well as monitor profiles. -

Hi There:
When I try to connect to the Oracle 8i via this applet , I get the following run time error.
Any help will be appreciated.
I am using j2sdkee1.3.1, jdk1.3.1_02 and Oracle8.
I also need your suggestion please. I have inserted some BLOB data in the Oracle table. I will need to display the BLOB data to the end users. I plan to convert this BLOB data into string format so that my applet can display the same. Further the string will have to be edited by the end users. I will then convert this modified string back to byte array so that I can insert the same as BLOB.
Please let me know applet or the servlet? Which is better option.
Users are reluctant to use any kind of WebServer because it will introduce the additional layer of complexity.
Any help will be greatly appreciated.
Thanks in advance.

Unable to Load USB Driver in LV for Total Phase's Aardvark I2C adaptor
I have tried to instal Total Phase's Aardvark I2C USB driver for LabVIEW on two computers and two versions of LV (8.5 and 7.1) without success. The Windows driver seems to be working fine as their command center gui terminal-esque program works without a hitch, but the LV DLL doesn't seem to work.
Attached is the very simple vi to find connected Aardvark USB devices (aa_find_devices). It always returns the same error code, 8002, which resolves to:
AA_UNABLE_TO_LOAD_DRIVER
-2
unable to load USB driver
From their documentation: http://www.totalphase.com/docs/aardvark_datasheet/sect005/#s5.9
This looks like perhaps the LabVIEW DL, "aardvark.dll" maybe having a versioning issue. So my question is this: Using LabVIEW, how does one debug dll dependencies and resolve issues like this? Do I need the source code for the lib?
Cheers,
Joe Gorse
Solved!
Go to Solution.
Attachments:
find_devices.vi 11 KBDear Joe,
Let me start off by apologizing for the inconvenience you
have gone through. I am an engineer at Total Phase. We are
working on fixing this issue for our next release of the
Aardvark LabVIEW Driver. This forum post was only brought
to our attention today. In the future, you can also let
Total Phase know about these kinds of issues by emailing
[email protected] We are very responsive through
email or phone.
The problem you are experiencing has to do with versioning
issues between our DLL and USB driver. Specifically, DLLs
before v5.xx must use the older version of our USB driver.
By replacing the DLL from our latest version of Control
Center, you have effectively upgraded the DLL that the
LabVIEW driver is using and made it compatible with v2.xx of
the USB driver.
The most likely reason that smercurio_fc did not see a
difference between the DLL in Aardvark Control Center and
the LabVIEW driver is because he is using an older version
of Control Center and correspondingly an older version of
the USB driver.
The reason that we have not packaged the LabVIEW driver with
latest DLL is due to the fact that a few functions have
changed their function prototypes (for example aa_open_ext
and aa_spi_write), and the VIs have not yet been updated
accordingly. Although updating the DLL solved your USB
driver issue, it introduced this new issue. If you try to
use these certain VIs, LabVIEW will error out.
We are currently working on updating the LabVIEW drivers to
work cohesively with the new DLL and USB driver, and this
should be available soon. If you need immediate
availability to the functions with new prototypes you will
have to change it manually. The other recommended option is
to simply revert back to the DLL that is packaged with our
LabVIEW driver and downgrade the USB driver back to v1.xx.
I will make sure to post again once the update is released,
and I once again apologize for the inconvenience.
Best regards,
Etai -

Why? File xerces.jar Placed with application (in /opt/gorod/axiom/WEB-INF/lib) and have all permissions.
Also I try to start java with -Xbootclasspath/a: option but it has equal result.
PS Sorry for my english :-\mv xerces.jar $J2EE_HOME
cd $J2EE_HOME
java -Xbootclasspath/a:xerces.jar\;jaxp.jar -jar oc4j.jar &
No changes :-(
But with
java -Xbootclasspath/a:xerces.jar:jaxp.jar -jar oc4j.jar &
