Most modern printers are efficient enough to hardly use any power at all when in sleep mode, thereby making it nothing more than a hassle to turn it off when you’re not printing. As for changing the connection type, I see no reason why you should change it… If you just want a wired connection, you should use an ethernet connection to your router, as USB would require an extra step if your router doesn’t have one built-in: buying a print server which would then convert the USB to ethernet.
Could you provide the model numbers of both your printer and router?
I’m glad I could help! I just looked up your printer and found that it doesn’t have an ethernet port. So, if you want to print from devices on your network, you’re going to want to keep the connection over wifi. If you decide for some reason you want a wired connection to your router, you’ll have to use the USB and a print server as detailed above… But, it seems like you’re all set!
Jake, a wired connection for a printer is always best thought, correct? I have been told that a USB connection can be bad because it can lose connection especially if you are trying to print something with many pages.
