The text tool is one of the most powerful tools in your toolbox because it opens the door to a multitude of pre-designed font libraries. These font libraries allow you to create graphical versions of letters using pre-designed formats. Photoshop handles these font libraries just as it would any image.

To place text based images in your canvas you need only select the text tool from the toolbox and click on the canvas in the area you want the text to appear. When you do so, the Type Tool Dialog will appear.
