COMPRESSED
CHARACTERS ON THE SAME LINE.
By deleting the semicolon at the end of line 10 and adding a semicolon
to the end of line 30, you can mix all six print pitches on a single print
line.
In program lines 30 to 70, CHR$(14) and CHR$(20) move the
printer in and out of Expanded Mode.
This program turns Compressed Mode on in line 40, and Com-
pressed stays on until the Reset Code turns it off in line 80. It gets
replaced (masked) in line 60 when the program turns on Elite Mode,
which has a higher priority.
Since doubling the width of the three standard pitches adds more
dots to the matrix of each character, doubling gives you a darker
print. There are other ways you can get darker print, plus many other
ways you can change the looks of the type, and we discuss these tech-
niques in the next three chapters.

Summary

The FX uses a dot matrix to plot the characters it prints. Vertically,
the matrix consists of 6 main and 5 intermediate columns. Horizon-
tally, the matrix consists of 9 rows. Appendix A shows how each of
the FX's characters fits into this matrix.
Using these potential positions, the print head is capable of printing
in a large variety of modes. In this chapter we introduced three sets of
commands that add five pitches (widths) to the factory-set default,
Pica. You can change the default to Compressed by changing DIP
switch 1-1.
Table 3-1 shows six pitch modes, their densities in characters per
inch, and the commands you use to turn them on. In this table, we
assume that you are using Pica as the default. If you have changed to
Compressed, you activate Pica with CHR$(18).
