HP Universal Print Driver (UPD) problem with tcp/ip port

Hi,
We are facing, since few days, problems with HP UPD in windows 7. Let me explain.
For some reasons we need the auto update feature of HP UPD, but this feature does not works anymore.
We found that, when installing a printer, if we name the tcp/ip port with the dns name or ip the auto-update will work, but if we name the TCP/IP port with dummy text, the auto update feature won't work (can't connect to the printer). This is like the UPD
try to resolve the tcp/ip port name instead of tcp/ip port address.
This was working last month. We installed some windows updates on clients, and one of these updates screwed up the UPD. I have the list of installed updates but there are many, and if someone already had this problem and can help it would be nice. And if
nobody can help, maybe this message will put other poeple with the same problem on the way to solution.
We don't want to update the driver (too much printers involved, too much clients also)
Thx for reading and helping !

  • Problem installing Laserjet 4050 in Windows 7 x64, No driver in Universal Print Driver v5.0.3

    I have just installed Windows 7 64Bit operating system.  I have be successful in installing several other more recent HP printers in the office.  However, my main "workhorse" printer is a HP Laserjet 4050 and I have downloaded the Universal Printer Driver v5.0.3 for Windows x64 - PCL 5 and PCL 6, and in both cases it does not find a suitable driver. The HP download site states these Universal Drivers will work, but I cannot get it to install.
    Is there a driver that will work on the 4050 in Windows 7 X64?  Thanks everyone.

    You're probably getting the "Windows cannot locate a suitable printer driver" error if you're trying to add the driver while adding a printer that is shared over the network. You see, HP's Universal Printer Driver (UPD) doesn't contain the PnpIDs of every printers it supports, so when you specify HP's UPD as the drivers for the network printer, if Windows can't find a match for the printer's PnpID it spits out the driver isn't compatible.
    The way to overcome this is to install a "generic" printer locally, using HP's UP driver, and change the port afterwards to point to the shared printer. So, first, add a local printer (that will be using the LPT1 port - make sure no printer is attached!), and click on "Have disk(s)" to browse to and select HP's UPD. Going through the remaining steps should install a locally-attached printer named something like "HP Universal Printing PCL 5" (or "[..] PCL 6"). You'll then go in the new printer's properties, on the "Ports" tab, and click on "Add Port...". If you're installing a shared printer, you'll select "Local Port", click on "New Port..." and specify the path to the printer (e.g. \\myserver\hplaserj) as the port name. Those steps should do the trick.
    Last thing: beware, though, as HP's UPD PCL 6 might not be compatible (anymore) with your LaserJet 4050, as they use a PCL XL class number/revision (class 2.1; sort of a version number of the protocol) that is higher than what your printer's firmware might support for PCL6 (should be class 2.0) I know the latest versions of HP's UPD PCL 6 doesn't work with our LJ 4000 & 4050 printers, so you might have to use the PCL5e driver for those 64-bit workstations.

  • HP Universal Print Driver version history or changelog impossible to find

    Most software developed typically has a version history, also known as changelog, available to review changes since version X that the company has had involvement in development with.  With the HP Universal Print Driver, UPD, this appears not to be the norm.
    I found a document for release notes of HP Universal Print Driver v5.5.0.12834 which only has a narrow focus of a subset of the version history for that release found here: ftp://ftp.hp.com/pub/softlib/software12/COL40853/ds-99397-4/UPD_5.5.0.12834_ReleaseNotes.doc  I've attempted to navigate the illogical structure of the ftp site to no avail to find anything that would be release notes for a previous version.
    I'm trying to find the version history compiled in one nice location so that I may confirm something.  If an example of what a changelog should look like please refer to this example: http://www.slysoft.com/download/changes_anydvd.txt

  • Conflict Between HP Universal Print Driver 6.0 and Office 2013

    Has anyone else noticed a conflict between the HP UPD v. 6.0 and Office 2013?  We are running a Citrix environment with Office 2013 installed on a couple of application servers.  Almost all of our printers are HP's, and we were trying to use the latest UPD (6.0) on our print server.  However any time users print out of Outlook (yes people still do that) it crashes out and needs to be restarted.  Printing from other applications works just fine.  As a test I have tried the UPD v 5.8 and it seems to work ok.  Obviously I've found a solution I was just curious if anyone else has noticed this conflict.

  • HP Universal Printer driver no longer supporting T790ps

    T790ps 44in Printer no longer available to be added using HP Universal Printer Driver PCL6 - 
    Was this removed from supported printers?
    We only use IP printing and this printer is no longer able to be mapped using the HP UPD PCL6 - 
    Can someone please advise / update on this comment?
    Thank You - 

    Sorry, I should have asked this earlier, what version of Windows are you using? 
    Since I don't want to waste too much more of your time with you waiting for me to reply, I will go ahead and give you two links of troubleshooting steps that I would recommend trying.
    The Progress Bar on the Software Installation Stops or Stalls
    'Device Setup Failed to Complete' or 'Unknown Device' Message Displays on the Computer in Windows Du...
    The first one addresses the issue of the software not completing. The second, even though the title might not seem like an issue that you are having, addresses the issue of the printer not being recognized by USB.
    Try those and let me know if either of them work. If they don't, get back to me with your version of Windows and I will see if I can find anything else to help you resolve your issue.

  • HP Universal Print Driver

    We have a print server with various models of HP printers. I have noticed that some newer models of HP printers come with the Universal Print driver rather than an individual print driver for that model. My question is does installing the Universal Print Driver on the server interfere in any way with the HP printers we have already installed. We have mainly laserjet 4000, 4050, 4250 and have them using there own driver. I understand that installing the UPD won't automatically make all printers suddenly start using that driver, but just want to make sure it doesn't affect them in any way like updating the odd dll. Is anybody running a mix of invidual drivers and the UPD? Did installing the UPD cause any issues?

    The UPD should not impact the discrete (product specific) print drivers, unless there are shared component (dll) files. One thing to consider, is the PCL drivers do share the same unidrv "core" with other drivers (not exclusive to HP), which is provided by Microsoft. [The same holds true for the PS driver, and the pscript.dll core]. This core can be updated by a MS hotfix/patch/Windows Update, or by another company updating their software (ie. print driver update). MS acknowledges the update of this core may cause delays to a printing environment, while the update is occuring.
    Additional info can be found at: http://support.microsoft.com/kb/967499. Although the document is written for clustering, it applies to other Windows technologies as well. 
    There is some pretty good documentation for the UPD, found on the "documentation" tab of www.hp.com/go/upd. The System Admin Guide discusses the ins-and-outs of the driver, migration strategies, and things to consider before implementing UPD in a print environment.

  • How-to for custom universal printer driver

    Need to make a customized print driver, one time only.  Not going to make a career out of this.  
    Is there a simple, step-by-step how-to for that anywhere?
    (I've seen the 220+ page "guide", and that is not what I'm after. Way too many words for my ADD brain.)
    Thanks very much.
    This question was solved.
    View Solution.

    OK, Windows XP may not be quite as flexible in controlling what a determined user could do, but I would suggest the following:
    Download and install two drivers, the Laserjet Enterprise 500 color M551 Printer series driver and the HP Universal Print Driver for Windows PCL5.  After the printers are installed you can rename and customize them.  I would suggest calling the universal driver one "Black Printing" or some such.  Click Start, Control Panel, Printers and Faxes, right click on the HP Universal Printing PCL5, Properties, General, rename the printer to suit, Apply, click the Device Settings tab, scroll down near the bottom to Color Printing Mode and set this to Off, Apply, click the General tab, Printing Preferences, chooese the appropriate default print settings  (it may be desireable for this printer to select Economode in the Paper/Quality tab), OK.
    Similarily set the appropriate name and settings for the Laserjet 500 Color M551 version.

  • Problems with the USB Ports

    Hi there,
    I writing this because I'm having some really big problems with my USB ports.
    A few days ago I plugged in an USB-Hub that was quite cheap. Suddenly a window popped up saying that a USB device was deactivated because it "needed" to much power. Since this happening, two of those windows keep popping up everytime I boot the MacBook. I called Apple and got some help: I had to delete some .plist files and clear some caches. The man who helped was able to find the error and deactivate the notification, he also told me to make a PRAM- and a SMC-reset. The man said that it's just a software problem and that I have to reinstall the system if we don't find a solution. So, one day later I reinstalled the system (Lion) and not only didn't it help, the two notification windows were popping up again...everytime I booted the Mac. So I decided to formate the whole hard drive and install Snow Leopard -> still the problem with the USB ports. After that I installed Lion  -> still the problem with the USB ports. I even tried to extract the .kext files that are important for the USB functionality from an earlier Combo Update, but it didn't help either. The point is, that the Mac doesn't recognize my external hard drive or any of my iDevices. Sometimes it recognizes USB sticks, but only after 20 seconds. The data transfer on both USB ports is also very slow. If I'm lucky and Mac recognizes one of my USB sticks, it takes like an hour for 1GB to be transfered on the USB stick or from the USB sticks to the Mac.
    I really don't know what to do and need help, especially because my backup data is on my external hard drive which I can't access because of this problem.
    I really hope that someone can help me, I'm very thankful for every answer that could help me!
    PS: Sorry for my bad English, I hope that everyone understands what I mean, please tell me if you don't get what I'm trying to explain in the text above.
    Sincerely,
    iLoud
    [UPDATE] I downloaded "USB Prober" and copied the Output file, maybe it helps:

    Is there support for Windows Server 2008 R2 for the CP2025n printer,  I've been trying to get it to work with a standard TCP port with the universal driver but no luck.
    Any ideas?

    I have Windows 2003 servers with the Universal PCL6 driver v5,4.  It printed slower then the previous version.  I manually changed the Device Settings, mainly the Monochrome / Color option.  This seemed to make the print process faster.

  • Printing with xerox universal print driver

    We just recently purchased a new computer for the office
    that has Windows 7 x64 Professional with Adobe Acrobat 9 Standard (9.1.2).  We have a Xerox printer in the office that only has a Global Print Driver (5.173.11).  Whenever we try to print to this Xerox through Adobe we cannot change the paper size from 8.5x11.  When we change the paper size in the Xerox driver, it does not update the paper size adobe will print to.  It seems like Adobe is not communicating with the Xerox driver properly and I don't know how to force a paper size in Adobe without the driver telling Adobe what size it will be printing.  Any ideas how I can get Adobe and this print driver to communicate correctly?

    Update Acrobat 9. I think you need at least 9.2.2 for Windows 7 compatibility. Upgrade to the latest 9.3.4.
