Is it possible to print from a Macbook air to a Kodak 3.2s wireless printer?

I have downloaded the latest drivers but I receive the following message when I try to load them: "Install software" can't be opened because it is from an unidentified developer. "install software" is on the disk image "KODAK_AIO_printer_v7_7-2.dmg". Safari downloaded this disk image today for support.en.kodak.com
