Print Quality

In the last chapter you learned how to change the width of the printed characters to achieve six different print pitches. The FX printer also offers several modes that improve print quality without affecting pitch. The three new modes that we discuss in this chapter are Double-Strike, Emphasized, and Proportional. After we cover these modes separately, we discuss combining them with pitch modes.

Bold Modes

Each of the modes we discuss here produces darker characters than do the Single-Strike modes we discussed in Chapter 3, and each gets its bold effect by printing overlapping dots. Because Proportional Mode includes Emphasized, it also produces bold characters. The difference between Double-Strike and Emphasized Modes lies in the direction the print head moves before it prints the overlapping dots.

Double-Strike Mode

The Double-Strike Mode prints each line twice. You turn Double- Strike on with ESCape “G”. It stays on until you turn it off with ESCape “H”. To see its effect, try this:

NEW

10 LPRINT CHR$(27) "GDOUBLE-STRIKE PRINT IS DARKER"; 20 LPRINT CHR$(27) "H THAN SINGLE-STRIKE"

and RUN it:

DOUBLE-STRIKE PRINT IS DARKER THAN SINGLE-STRIKE

In this mode the individual dots are less noticeable, and the characters are more fully formed than in Single-Strike.
