HP Support Assistant not detecting printer



Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 


I understand That the support assistance is not detecting the printer.

Don't worry I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 


Are you facing this problem after an update?


Let's try to fix this issue by doing a clean install. 


Follow the steps mentioned below:


First, unplug the USB cable from the printer is present.

Go to Control panel - Programs and feature - Select all the HP Officejet Printer entries and uninstall them.

Now go to Control panel - Devices and printer - Select all the printer entries and remove the device.

Restart your computer.

Click the bottom-left Start button on the desktop, type device manager in the search box and tap Device Manager on the menu.

Once in device manager, click on the view tab in the top & choose "Show hidden devices".

Then from the device manager list, check the entries under "Printer" - If there are any entries, please right click and choose "uninstall" - In the confirm device un-install pop-up, make sure you select the box which says "Delete the driver software for this device".

Also, check the entries under "printer queue" and "imaging devices" and repeat the same exercise. 

Delete any printer entry or any entry which says "Unknown device".

Once done, close device-manger. 

Then press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" and press enter.

Under print server properties, go to drivers - remove any entry there as well.Again, go to Run window, type - "c:/programdata" - Go to Hewlett Packard folder, remove any printer related folders & files.

Once done you can try cleaning out your temporary files and cached files. 

You can try using automated applications like some cleaner software's that you can download from the internet.

Now restart your computer again.Open the Run window again, type "services.msc" and press ok to get services window.Scroll down to "Remote Procedure Call (RPC)" - right-click and go to properties. 

Make sure the service is started and startup type is "Automatic".

Now scroll up and go to "Function Discovery Provider Host" - right-click and select properties - Change the startup type to "manual" and start the service.

Repeat the same exercise on "Function Discovery Resource Publication" as well.

Click here to download and install the software.


Keep me posted, how it goes!

HP Support Assistant not detecting printer

Hi! @CADDIE37, I am the Mr.Robot. It looks like you were interacting with @Raj1788, but he is out of the office today, so I'll take over from here.


I appriciate your efforts for writing back to us.


As you mentioned the issue still persists after trying out the steps.


Try the steps recommended below.


I would suggest to turn off any Firewalls and Antivirus software temporarily and run the HP Support Assistant Software again.


Run any Windows updates.


Uninstall and reinstall the latest version of HP Support Assistant Software if the issue persists: HP Support Assistant.


Reregister the Windows Installer:

Open the run box by holding the Windows key and the R key.

Type in msiexec /unregister then click OK.

Open the run box by holding the Windows key and the R key.

Then type in msiexec /regserver then click OK.
(make sure you are typing it in exactly there is a space in between)


Then reinstall the HP Support Assistant Software.


Try finding the printer again.


Also, refer this article to further troubleshoot HP support assistant issues.



If the solution provided worked for you, please mark accepted solution for this post.


Hope this helps!

Take Care! 🙂
