As I understand you need help connecting your printer via USB 3.0,
No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
Did you know USB ports are backward compatible?
(therefore, a USB 2.0 device should work just fine on any USB 3.0 port as well)
Did you check if any other device is getting detected on the USB ports?
If none of the devices are getting detected on the USB ports, please use the below steps to troubleshoot the ports on your hp laptop:
Some USB devices, such as printers, scanners, and copiers require that the USB device software and drivers be installed before connecting the USB device to the computer. Always follow the installation documentation from the USB device manufacturer.
While troubleshooting the USB device, you might need to disconnect the USB device from the computer.
Always follow manufacturer instructions for disconnecting USB devices from the computer. Some USB devices must be turned off and/or ejected before they are disconnected from the computer. Some other USB devices support the Windows Safely Remove Hardware feature.
Perform the following steps, as applicable, to troubleshoot USB devices that are not working correctly:
Power: If the USB device operates on battery power, make sure the batteries are correctly seated and are functional. If the USB device operates on external power, make sure all the power connections are secure and the power cord is connected to a power source.
Test the USB connection: Sometimes, simply disconnecting and reconnecting the USB device to the computer can solve the problem:
Disconnect all USB devices from the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.
With all USB devices disconnected, do one of the following:
If you have a desktop computer, connect the device that is not working correctly to one of the USB ports on the back of the computer (the ports attached directly to the motherboard).
If you have a notebook computer, connect the device that is not working correctly to a USB port on the notebook. Do not use a USB port replicator (such as a docking station or USB hub).
