The < ESC > “J” CHR$(n) command causes the printer to make one line feed of n/21 6 inch, but does not change the setting of the line spacing. Try this program to see how it works:
NEW
10 ’ Demo of
20LPRINT “LINE NUMBER1.”
30LPRINT “LINE NUMBER2. ‘I;
40’
50LPRINT CHR$(27) ;“J”;CHR$(lOO) ;
60LPRINT “LINE NUMBER3.”
70LPRINT “LINE NUMBER4. ”
80END
Here is what your printer will produce:
The < ESC > “J” CHR$( 100) 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.
