Summary; Even Columns With Unidirectional Mode - Epson FX-80 User Manual

I
Figure 9·9. Even columns with Unidirectional Mode.
The difference is very subtle, but Figure 9-9 does look more uni-
form. Did you watch the print head as it printed? It printed in only
one direction instead of two. That helps to line up the columns for
finely tuned printouts. We used this mode in the TICKET program of
the "One Easy Lesson," and we'll use it again in Chapter 19 to help line
up our user-defined graphics characters.
<ESC) "Ul" turns on Unidirectional Mode and <ESC) "UO" turns it
off. There is also a Unidirectional Mode that turns off at the end of one
print line-you tum it on with <ESC)"
