What is a good site to go to learn about business copyer and printers ? -

I just started working at staples and trying to learn all I can about the differnt things we use in the copy and print center . I know some but want to learn more to help me. So any sites that help to learn how to use them or about them would be good . The more I know the better it will help me at work . So any thoughts of Ideas would be helpful ! Thank you
