Solved Printer Not Working

About 2 weeks ago I started getting an alert from SupportAssist (I run Windows 8.1 on a Dell Inspiron 2350 computer) stating that "Driver Not Installed On: Intel(R) 8 Series/C220 Series B xHCI HC - 8C31." When I click on "install" I get the following message:
"The drivers for this device are not installed. (Code 28)There are no compatible drivers for this device.
To find a driver for this device, click Update Driver."

However, I'm unable to update the driver. I get the following message:
Driver Provider: Unknown
Driver date : Unavailable
Driver Version : Not available
Digital signer : Not Digitally Signed

The only problem this is causing is to my printer - I am unable to print. I get the following message:
"The printer is offline.
Check that the printer cable is connected and the printer power is on."

I have scoured the internet looking for a possible download to fix this problem, but can't find anything.

As I stated, this problem just started about 2 weeks ago - up until then my printer worked fine. I have no idea what caused this problem.

Would greatly appreciate any advice on how to get my printer working again.

Tks in advance for any input - jcm

You can get those drivers from Intel's website. However, they shouldn't have anything to do with a printer, unless you are also missing USB port drivers, which may also be from Intel. Check device manager and see what drivers you are missing, if any.

I already tried Intel's website, but can't find any drivers that I might need. Had them scan my system, and they couldn't find any either. Tks for response, though - jcm

I generally would ignore any type of software that is supposed to tell you if you need drivers or not. Does Device Manager show any missing drivers?

Device Manager says I have one device without a device driver (the one I mentioned in my first post), Initially, Device Manager said that I was missing the driver for USB xHCI Compliant Host Controller. But, I inadvertently uninstalled it, and then the device without a device driver was changed to Intel(R) 8 Series/C220 Series B xHCI HC - 8C31. Device Manager is saying that I am only missing the one device driver now. I am completely baffled, as the printer was working perfectly up to a couple of weeks ago. I don't know of anything I could have done to my computer (no new programs installed) to have affected the settings. I appreciate your assistance. jcm

Because the big factory builder typically brand their components, in effect, making them somewhat proprietary, I recommend you get your drivers from the computer maker, not the device maker. So have you checked the Dell site for drivers.

I would also totally uninstall the printer, for now.

I note too that AiO has both USB 2.0 and USB 3.0 ports. If this is happening with 3.0, try 2.0 or vice versa.

Earlier today I decided to do a system restore - had wasted enough time trying to find out what the problem was. Printer now working. My thanks to those who responded. jcm

Glad you got it sorted. Thanks for the followup.
