I have a H-P Compaq

Question

I have a H-P Compaq Presario A900 Notebook PC and it came with a Canon Pixma MX310 all in one printer. It has windows vista 2007 on it (computer) and one of the instructions says to open the vista program and I don't understand what that means. Also the printer did'nt come with a usb cable. I have wireless internet if that matters. I don't understand how to hook it up to the computer and I followed the instructions. Help
