MAC ID is like a serial nr of your network card. On a windows system you can know what you're mac id is through START > RUN > type "cmd" without the quotes > type "ipconfig /all" without the quotes. In the list you'll see the MAC ID is listed (sometimes it's called Physical Address instead of MAC ID). For each network card in your computer (usually only 1) there exists a MAC ID.
There is usually a sticker on the bottom of printers that will have the S\Y and MAC ID numbers recorded there next to a barcode.
To spoof a mac ID, you will need to know the mac ID you want to spoof. After that, how you implement it depends on your operating system or hardware. http://www.tech-faq.com/change-mac-address.shtml provides in depth details on how to change your mac address for a variety of operating systems.
This is a unique machine ID, also known as 'Mac Address' in terms of networking.
