head moves across the paper, with the second dot printed slightly to the right of the first. This process produces darker, more fully formed characters.

In double-strike mode, the print head goes over each line twice, making the text bolder. For even greater boldness, emphasized and double-strike can be combined. The following samples show the different effects you can achieve.
