Upping 2.4ghz bands from 1 to 3

[Jennywren3]

I switched to sky broadband and it has multiple 5ghz bands but only 1 band on 2.4ghz frequency. Can I change router so it has  more 2.4ghz bands as my printer is only 2.4ghz band frequency. This means I can't connect both android phone and android tablet. I've been transferring screenshots etc to phone then printing.
