Welcome to the HP Community Forum.

The printer tolerates / supports connection to 2.4GHz and 5GHz though not at the same time.

Sample Product Specifications for the HP DeskJet 4120e All-in-One Printer (26Q90B)

If the router supports it, create a separately named SSID named network for each frequency (band) and connect the printer to the SSID named network you want it to use.

To some extent, how you connect depends on the device you are using.
