Incoming and Outgoing Printer Ports

Yes. It used to work before. 

Thanks.

After disabling Norton and understanding no changes have occurred to neither router nor antivirus, this may seem like an obvious troubleshooting step, but have you tried uninstalling and reinstalling the driver?

Do that then reboot the PC. Ensure the printer has a valid IP address and then tell me the exact error message you get when you try to print.

Keep me posted 🙂

Hi, I've been referred to this post by another HP Forum contributor.  I have the HP Officejet L7590.  Everything worked fine on all 4 or my PC's, no two of which are alike, and all of which had been updated to win10 August 3, 2015, until about 10 days ago.  At that point in time a new MS update to win10 occurred and that's when none of the pc's could access Print or Scan and there was a warning that the HP driver needed to be updated. 

I found the updated HP driver for win 10 for my printer on HP Support.  I uninstalled all the old HP apps, installed the new driver, and on every single PC the experience is the same.  Warning occurs that ink levels will not be seen and I should unblock UDP 161.  Indeed, that and other printer info that used to be visible on Solution Center are no longer working.  I CAN Print and Scan thru Solution Center.  

I read your post about unblocking the ports on the Router too.  I have the Netgear R7000 router.  I've unblocked the UDP ports 161 and 427 both on my PC firewall and the router.  No change in Solution Center behavior.  Since I never changed any Firewall or Router settings before and this all happened after the latest win10 upgrade and the win10 HP updated driver for my printer, what do you suggest NOW?

Have you tried temporarily disabling your anti-virus during said attempts?  Just trying to think of something else to try.

However, I want to make sure I can better understand your inquiry.  Do you say you can print and scan in Solution Center? If so that's awesome but I am thinking how I see your issue is mainly every last one of your Win10 PCs cannot print, scan, or see ink levels.  Please just a little clarity there so I can give you some extended advice on the exact issue (just a brief quick description of the issue - nothing extensive).

I'm assuming that once you've been directed to this post that perhaps you have tried everything, however I keep tricks up my sleeve.  And I posted every single one of those tricks on another forum post.  Although it may have a different title than your issue, it seriously lists everything to try.  But I am sure I can think of a few more if none of them work.

I'm just throwing this link out there for you just in case I take a while to respond.

I hope I can help!

Thx, sorry for the confusion I caused. Initially I could not get Solution Center to install with the updated HP win10 driver when I initially posted to your colleague, Drakster. That's fixed! If you want to know how, all I can tell you is I waited a few days, another win10 update from MS occurred and I simply repeated what I previously had tried. This time Solution Center installed on all but one PC.

Drakster pointed me to run MS sfc; did that; ended up resetting that PC, Solution Center installed; now all 4 pcs in same state: I CAN PRINT & SCAN FROM SOLUTION CENTER even though it says "printer disconnected"! No ink levels or tools, but all that works thru web print. It's the COMM problem with Solution Center I now need to fix

[VisionAiry]

Well, I'm just thrilled to hear about that second update. I knew some of my colleagues were working on that so I'm happy they found the solution.  You clarified all that before I'm just so used to hearing people can't scan or print with Solution Center so it threw me off a bit.   As far as ink levels go, there is going to be a .dll file that needs repaired that controls that but every computer differs so I'm not able to specify if it is in the system or system32 folder and if I can't give an exact answer I won't.

You could always try setting a static IP as a first step or adding it as if it was a second printer from All Programs/HP folder as a test but this very well may be one of those things that may never communicate again after all the trouble I noticed people had with that old software on win10 PCs. Hard to say if I'm not there to play around with it on your PC. 

Just really happy you can scan and print!!

[SoCalGuy]

Thanks, VisionAiry. Yes, it's a relief that printing and scanning works fine, but a disappointment that HP can't get its win10 driver to install the correct dll files, and perhaps worst that the error message gives useless information. It shouldn't be so difficult to install and use all the printer functions. After all, it worked fine in Win7 and win 8.1.

[VisionAiry]

Yup - every time Microsoft upgrades their OS it takes a while to work out all the minor details I suppose.  Keep an eye open for Microsoft Updates to see if your PC is up to date.  It seems all the latest fixes have been included in those.

Did you try just adding it as if it was another printer?  Check your HP Printer folder for an option to add a printer and see if that helps.  It will show up as (copy 1) most likely but if it doesn't fix it you can just go into your Devices and Printers folder and remove it.  That's what fixed my Solution Center issues.

[SoCalGuy]

Let me verify that I correctly understood your suggestion--I know how to add the PRINTER using MS built-in win10 drivers. And I know how to remove a printer (or disable it). I purposely did NOT try that "generic" driver for my printer because the last thing I want to do is screw up what functions I now have thru Solution Center. At least I can print & scan from apps and thru Solution Center now and I access all the tools and ink levels thru the web print interface. If your suggestion will assuredly "cause no harm" to Solution Center functions I now have (or will at least will allow me to easily restore current functionality) I'm interested in trying that.

[VisionAiry]

Do allow me to clarify - It's not the generic driver when you add a printer using the HP printer folder (which I used to be able to tell you it is under All Programs in Windows 7 but now I can't). 

I have an idea....I'm almost off work.  How about I go home and try to add a printer to my Solution Center on my win10 and let you know how it works.  I don't mind sacrificing mine in the name of science.  It may take me a couple hours to get to that but I will gladly post the results.
