HP Smart app might display the “Printer status unknown” error message if your printer is idle or offline. If your printer goes into sleep or standby mode after a period of inactivity, press the power button to “wake” it.
If the error message, Unknown device appears, this can indicate that there is not adequate power and the PC can not identify the printer correctly. Verify that there are no extension cables and that the power cable is no longer than five meters. Reseat the power cables.
Restart the printer and try again. Unplug the printer from an outlet. You can plug it back in again to see if it works this time. Check if the printer is properly set up or connected to your computer`s system.
Make sure that both ends of the USB cable are correctly inserted into the computer and the printer. Try disconnecting and reconnecting the USB cable at both ends. Disconnect the printer and the computer and reconnect them. Try another USB port if available.
Status unknown means a circumstance where samples were scheduled to be taken by the regional water quality control plant and were not, samples were taken but not yet analyzed by the report due date or where a new discharger has yet to be sampled.
If you see an “unknown accessory detected near you” message (or similar), it means there`s an item compatible with the Find My network that might be traveling with you.

Next, under Network discovery, select Turn on network discovery. Under File and printer sharing, select Turn on file and printer sharing.
The optical sensor calibrates the printer to the specific ink cartridges and print heads, which eliminates the need for customers to manually calibrate the printer. The sensor also ensures the printer is properly calibrated to the print head nozzles to deliver optimal print quality.
During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems.

Run Diagnose & Fix

Open the HP Smart app, and then open Diagnose & Fix. Windows: Click the Diagnose & Fix icon in the bottom left corner. macOS: Click your printer, click Printers in the top menu bar, and then click Diagnose & Fix.

It doesn`t slow down your computer as there are no processes or CPU activity associated with them. It adds clutter to Device manager and in general I would say that you should either remove them or fix them. But it won`t have an impact on performance.
Ghost prints happen when the drum or fuser unit within your printer become faulty. Because a fault with this element won`t heat the particles of the toner to a high enough temperature, the marks being made on the paper are much lighter in colour and appear more faded than typical documents.
Open Device Manager. Right-click Unknown device and click Update Driver Software. Select the `Search automatically for updated driver software` option, then Windows will install the new driver automatically.
Go to your Google Account:

You might need to sign in. Under “Security,” select Sign-in & security. Select Devices. Next to the device you want to remove, select More Remove device.

unknown device just means that someone logged into the account on a device that was not previously associated with the google account.
Reset. Resetting the printer stops printing and clears the current print job received from the active interface. You may want to reset the printer when there is a problem with the print job itself and the printer cannot print successfully.
Restoring the factory-set defaults returns most of the settings to the factory defaults. It will not reset the page count, tray size, or language.
If the error message, Unknown device appears, this can indicate that there is not adequate power and the PC can not identify the printer correctly. Verify that there are no extension cables and that the power cable is no longer than five meters. Reseat the power cables.

Can printer cause WiFi problems?
ANSWER : It really doesn’t sound possible. Have you tried disconnecting the printer and seeing if that restores your wifi? I’ve had problems with my Internet service provider before. I found that I knew more than their techs did. The last problem I had was due to the router. They gave me a new one, but it had the same issues. I went out and bought a decent one and that fixed my problem.
