Can I print from a desktop, to a wireless eprinter, I do have Wi-Fi?

Just got a new eprinter to use with my iphone and hopefully my desktop, which of course is not wireless, I have Wi-Fi which I got for my grandkids when they visit. So is there a way to use the printer with a desktop? Please explain in very simple terms. While I'm not the worst at this sort of thing, this wireless computer is new to me and I don't understand it at all.

When you install the drivers, you need to select that it will be connected through 'Wi-Fi' or 'wireless' and just follow the instructions on screen.

once it's set up, it will be connected to your router, when you print your computer (wired or wireless) will be connected to the router and print through the network, any wireless devices will connect to the router through Wi-Fi and print.

if you do not have the CD/Drivers/Software that came with the printer, just go to the manufacturers website of the printer and put in the model number and download and install the latest drivers/software for it.
