User-defined Characters
This example of a character definition program should make this clear:
10
LPRINT CHR$(27)"x0"
20
LPRINT CHR$(27)"&"CHR$(0);
30
LPRINT '@@";
40
LPRINT CHR$(l)CHR$(9)CHR$(l);
50
FOR I=1 TO 27
60
READ-A: LPRINT CHR$(A);
70
NEXT I
80
LPRINT "@@@@@"
90
LPRINT CHR$(27)"%"CHR$(1);
100
LPRINT "@@@@@"
110
LPRINT CHR$(27)"%"CHR$(0);
120
LPRINT "@@@@@"
130
END

In line 10, the ESC x0 command selects draft printing.
The actual character definition starts in line 20. The two @ signs in line
30 represent
n1
and
n2,
the range of characters being defined (in this
case, a range of 1). Line 40 contains d0, d1, and d2.
The information about the actual character design (which is contained
in the DATA statements at the end of the program) is sent to the printer
in the loop between lines
50
and
70.
Note: When defining Letter Quality or proportional characters, put
a WIDTH statement in your program to prevent carriage return and
line feed codes from interfering with your definitions.
