You dont install wireless drivers to print wirelessly.

Your printer or your wireless print server is just like your laptop in
that, it has a wireless card. It receives wireless signals. You set up
the printer to communicate with either your wireless router (which
presumably connects to your DSL line) or you set up your computer to do
so. The printer will put off a signal which in your wireless screen on
your computer should say something like "Epson310" or something similar
identifying it.
