So for our example above, any of these BASIC statements
will
have the same result:
LPRINT CHR$(27);CHR$(87);CHR$(l)
LPRINT CHR$(27>;CHR$(87);CHR$(49)
LPRINT CHRS(27) ;"W";CHR$(l)
LPRINT CHR$(27);"W";CHR$(49)
LPRINT CHR$(27);"Wl"
Even though there are many commands
that require the use
of ASCII code 0 (the (NUL) character), the number "0" (zero or
ASCII code 48) cannot be substituted.
In these cases, instead of
an unadorned
0 we will show CHR$(O) each time these com-
mands are referenced.
That's it for the basics. You are now ready to learn how to use
the many features of your printer.
SOME SPECIAL KINDS OF TEXT
If you looked carefully at your printer's self test, you probably
noticed that it can print in italics. But that's not all! Your printer
can underline characters,
print superscripts
and subscripts,
and
perhaps most exciting, print near letter quality characters.
n Near Letter Quality characters
This printer's Near Letter Quality (sometimes
abbreviated
as
NLQ) character set is ideal for correspondence
and other impor-
tant printing, as it produces very high quality characters.
Nor-
mally, your printer prints draft quality characters.
This is ade-
quate for most work and has the fastest printing speed. For the
final printout, try NLQ. The program below shows an example.
10 ' Demo of NLQ character set
20 LPRINT CHR$(27) ;"xl";
30 LPRINT "This line shows NEAR LETTER QUALITY!"
40 LPRINT CHR$(27);"xO";
50 LPRINT "This line shows standard print."
