Old Printer with New Desktop

Hi its me again!

Ok I got my son to give me the make of the Desktop, it is an HP Envy H8-1430 and the printer I have is an old one, which i used a plug to plug into the back of the old PC, that is an HP Lazerjet1100. But there is no where on the back of the new desktop to plug it in, unless i have to get some type of adapter???? I really don't like this new PC, and I really don't like Windows 8!!!

Thanks again, I appreciate all the help!
