The < ESC > “J” CHR$(n) command causes the printer to
make one line feed of n/216 inch, but does not change the setting
of the line spacing. Try this program to see how it works:
NEW
10 ’ Demo of one-time line feeds
20 LPRINT “LINE NUMEIER 1. ”
30 LPRINT “LINE NUMBER 2. I’;
40 ’ One-time line feed
50 LPRINT CHR$(27) ;“J”;CHR$(lOO) ;
60 LPRINT “LINE NUMBER 3.”
70 LPRINT “LINE NUMBER 4. ”
80 END
Here is what your printer will produce:
The < ESC > “J” CHR$(lOO) in line 50 changes the spacing
to 100/216 inches for one line only without moving the
printhead. The rest of the lines printed with the normal line
spacing. Notice that both line 30 and line 50 end with semi-
colons. This prevents the normal line feed from occurring.
The < ESC > “j” CHR$(n) command works the same way
except that the paper moves in the opposite direction. Try this
simple change to your program to see the difference.
40 ’ One-time reverse line feed
50 LPRINT CHR$(27);“j”;CHR$(lOO);
