Print Quality Modes

There are two modes that produce boldface (darker) characters which make your printout more distinctive. These modes are Double- Strike and Emphasized. Each gets its bold effect by printing overlapping dots as explained earlier in this chapter. Figure 5-5 shows the difference between Single-Strike (the default), and Emphasized.

On the P-80, Double-Strike and Emphasized produce the same result. Double-Strike may produce a slightly different result when printed through your software.

The P-80 has a built-in Underline mode making it easy for you to underline anything. You can underline characters or blank spaces as demonstrated in Chapter 4.
