Software Support
All software packages
do
not automatically support all the features of
your printer. For example,
automatic
text underlining is not a
feature
of
all word processing software,
and
much software does not allow
font
switching.
In
addition,
some software packages may be
able
to perform a
task
on
one printer and not on another.
For
instance,
a word processing
program may support proportional
spacing
for one printer and not for
another.
For details on which printer capabilities
your
software
supports,
review the instruction manual that came with your software,
or
contact
your software point of purchase.
When your software
package
does not support one of
the
printer's
capabilities
(like
proportional
spacing), you may be able to use
printer control codes to perform the
function.
Since each software application is
unique,
read your
software
instructions carefully
before
using the printer
control
code
charts.
Some software allows you to embed control codes
within text or
data.
Other software allows you to pass control
codes only
as part
of
the
formatting
lines,
while some software packages prohibit
the
passing
of
any control codes to the
printer.
Methods of embedding printer control codes vary with software pack-
ages.
For
example,
IBM Writing Assistant
uses
the
•p or
*Printer
command to embed control codes. Multiplan
1
uses
the
alternate
button
(Alt)
for embedding the codes and also allows codes to be
passed in the printer formatting lines.
Most
software packages have
instructions for the use of printer control codes in its
operating
manual.
