CHAPTER 4 _ _ _ _ _ _ _ Bells and Whistles
Overview
If
you've
read this far,
you've
already set up your printer and
gotten it running with your computer. You can load paper
and change ribbon, and you know what the indicator lights
tell you and how to use the controls on the printer.
At this point you can print out information from a software
package using the printer's "default" settings
-
the kind
of printing set automatically when you turn the printer on.
So if you 're not interested in using the other features you
don't need to read any further. To review, these are the
default settings:
Data Processing Printing
-
high-speed bidirectional
printing at 7 60 CPS (characters per second)
Character size 7 0 CPI
(characters per inch)
Line spacing 6 LP/
(lines per inch)
-
the distance
between the bottom of one line and the bottom of
the next is 7 /6"
This character size and line spacing is the same as a standard
''pica"
typewriter set for single spacing.
But the MICROLINE
92/93
can do a lot more than pretend
to be a typewriter: it gives you an assortment of different
sizes
and kinds of printing, automatic formatting capabili-
ties, and graphics
-
you can
even
design
your
own charac-
ters.
This chapter describes these
"bells
and whistles" and
explains
how to use them.
The printing features are regulated by special codes
-
called
"control
codes"
-
which
the computer sends to the printer.
If
you 're
writing
your
own program, you send control codes
to
the printer the same way
you
transmit characters to be
printed
-
by including them in a BASIC "LPRINTi' state-
ment, for
example.
Software packages use a variety of
methods to handle control codes. The section called
"If
You're using a Software Package" beginning on page 65
outlines
a few of those methods, but you
'II
have to
look
in the instruction book that
comes
with
your
particular
package to find out how they work.
