Line 20 turns on elite pitch with (ESC) “M”. Line 30 prints a line at 12 characters per inch. The (ESC) “P” in line 40 resets the printer to pica pitch and line 50 prints a line in pica pitch.
W Expanded print
Each of the print pitches can be enlarged to twice its normal width. This is called expanded print. Try this program to see how it works:
10 ’ Demo of expanded print
20 LPRINT "Demonstration of 'I;
30 LPRINT CHR$(14);
40 LPRINT "EXPANDED";
50 LPRINT CHR$(20);
60 LPRINT " printing."
70 LPRINT "Notice that I';
80 LPRINT CHR$(14);
90 LPRINT "EXPANDED mode"
100 LPRINT "automatically turns off at the end of a line."
Expanded print set with CHR$(14) is automatically cancelled at the end of the line. This is convenient in many applications, such as for one line titles. Note that you didn’t need to put an (ESC) in front of the CHR$(14), although (ESC) CHR$(14) works just the same.
You can also cancel one line expanded print before a carriage return with CHR$(20), as done in line 50.
Sometimes you may wish to stay in expanded print for more than one line. Change your program to this:
10 ' Demo of permanent expanded mode
20 LPRINT CHR$(27);"Wl";
30 LPRINT "Permanent expanded"
40 LPRINT "mode stays on until"
50 LPRINT "is is ";
60 LPRINT CHR$(27);"WO";
70 LPRINT "turned off."
