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.
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.

Check all cable connections (including the power cord) on the printer side. If the printer does have power and you`ve properly connected the communication cable, but the printer is still not recognized, try switching to a different USB port on the PC.

Troubleshoot the printer USB connection

Check the USB cable for damage and recommended length, and then restart your printer and computer. Turn off the printer and the computer. Disconnect the USB cable from the computer and printer, and then inspect the cable.

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.
