Ok, imagine you have a wireless router with two printers connected, but DHCP is switched off so each printer has it's own IP address. You have a mobile phone used as a router, hotspot tethering switched on so laptops can connect to the internet through the phone, with DHCP switched on. So ideally, you would like to join the mobile network to use the internet but then switch to the other network to print. Is that possible? Is there some kind of network that could be set up to use both networks at the same time?
As far as I know most newer printers can be accessed through hotspot... As long as your phone sees the printers..
