Change the paper size to match the size of you design. If you want to create a business card, you can use the pull down menu on the options bar to select business cards for the paper size. Also change the orientation from portrait to landscape here if you need to.
Now design your business card or other design.
If you are going to be using purchased sheets of scored business card or label paper, jump to the "Printing on Label Sheets or Scored Business Card Paper" section. If you want to print in plain paper or cardstock, jump to the "Imposition Layout Tool" section.
