Q: How do I connect a printer

wirelessly or usb?

usually you have to run the printer driver installation software first (which might be found on a cd, or from the company's website), then go into print and fax -under system preferences, click on the plus sign, add the printer, choose the model,  then just plug it in to the usb socket on the machine.  Printer cables are a-b cables. the square shaped end usually goes into the printer, while the other flatter end goes into the usb socket.  After that, turn on the printer, wait for it to warm up, and then you should be ready to print something

as for wirelessly, I can't say right now, apart from reading the instructions, but the above stuff should work fine for usb

• OS X Mountain Lion and OS X Lion systems will have the necessary printing software already installed, or will automatically download and install software when the printer is connected or configured. Do not install software that came with the printer as it may be out of date, and do not connect the printer to your Mac yet. Follow the instructions that came with the printer to unpack, install ink or toner, and insert paper.  Finally, use the instructions in this article to connect the printer to your Mac.
• Make sure the printer model is listed in Printer and scanner software, which is a comprehensive list of all printer models that have compatible software for OS X Mountain Lion and OS X Lion.

you are not in a notebook oriented forum, and the OS X forums are also good.
