For Windows 11, this usually means Windows could not find a compatible printer driver after the printer was disconnected. Use this order:
- Check the connection first.
- If the HP 6970 is connected by USB, reconnect the cable firmly to both the printer and the Lenovo PC.
- Try a different USB port on the PC.
- If it is a Wi-Fi printer, make sure the printer is connected to the same Wi-Fi network as the PC.
- Restart the printer and PC.
- Turn off the printer and wait 10 seconds.
- Restart the Lenovo PC.
- Turn the printer back on and try adding it again.
- Update or reinstall the driver from Windows.
- Go to Start > Settings > Bluetooth & devices > Printers & scanners.
- Select the printer if it appears, then select Manage > Update driver.
- If Windows cannot find a driver, continue to the next step.
- Download a compatible driver from HP.
- Go to the printer manufacturer’s support website.
- Search for HP 6970.
- Download the driver that matches Windows 11 and the correct system type for the PC.
- Install the driver and restart the PC.
- Avoid drivers marked for older or unsupported Windows versions unless no newer driver is available.
- Remove and reinstall the printer.
- Go to Start > Settings > Bluetooth & devices > Printers & scanners.
- Select the printer and choose Remove.
- Restart the PC.
- Return to Printers & scanners and select Add a printer or scanner or Add device.
- Let Windows install the recommended driver.
- If the printer still is not recognized, restart the Print Spooler service.
- Press Windows key + R.
- Type services.msc and press Enter.
- Find Print Spooler.
- Right-click it and select Restart.
- If Windows still does not install it automatically, reinstall it manually.
- In the printer add flow, choose Add manually.
- Select Add a local printer or network printer with manual settings.
- Choose the correct port.
- If prompted for a driver, use Have Disk if HP provided one, or select Windows Update to refresh the printer list.
A good check at the end is to print a test page to confirm the printer is working.
