Print Quality; Bold Modes; Double-Strikemode - Epson FX Series User Manual

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
18 LPRINT CHR$(27)"GDOUBLE-STRIKE PRINT IS DARKER";
29 LPRINT CHR$(27)"H THAN SINGLE-STRIKE"
and RUN it:
D O U B L E - S T R I K E P R I N T I S D A R K E R T H A N S I N G L E - S T R I K E
In this mode the individual dots are less noticeable, and the characters
are more fully formed than in Single-Strike.
