Business Application; Preparation; Barchart - Epson FX Series User Manual

In this chapter we turn our attention to business applications. First
we program a sample barchart. Then we use designs from previous
chapters to develop a program that puts the FX through its paces.
The programs pull together many of the programming techniques
that you've used in the course of this manual. The second one is con-
siderably longer than the programs in previous chapters, and the
length provides two benefits. First, you'll have a chance to really test
your own understanding of the FX printer. Second, a longer program
shows you how versatile your printer can be.
