Every business person needs to have business cards. They're a fast and convenient way to give a prospective client or customer your contact information and basic marketing message.
It's important to get the best quality business card that you can afford. Pay attention to the quality of the paper and the printing as well as the design. People are impressed by these things, and will judge you and how well or poorly you might treat them by the quality of the business card you hand out.
Your business card represents you. Don't spoil the good impression you've made in person by handing someone a home-made card printed on your home printer (unless you have the kind of expensive printer that can produce the same quality business cards as the local print shop).
Otherwise, you should always have your business cards professionally printed. You don't want to give prospective clients or customers the idea that your products and/or services are second rate.
