I'm guessing Lexmark with a model name like that. The only manufacturers of internal wireless (or standard Ethernet for that matter,) are the companies themselves. Unless Lexmark makes one, you’re out of luck.
However, there are several alternatives. Here's the cheapest (It's free! :D) If you have a dedicated computer nearby that is connected (directly, or indirectly) to a wireless hub or router, you can easily set the printer up on that computer and set the computer to share the printer connection over your network. You will then be able to access the printer through any computer attached to your network, both Ethernet and wireless. You may have to adjust some firewall settings to allow the printer to be shared, but it is definitely possible.
Feel free to email me if you have any questions or would like help setting up printer sharing.
