nMoving down the page without a carriage return

So far, all the commands that move the paper also move the print head to the left margin. And normally this is what you want. Sometimes, though, you may wish to move down the page without moving the printhead back to the left margin. The following commands do just that.

The (ESC)“J”CHR$(n) command causes the printer to make one line feed of n/180 inch, but does not change the setting of the line spacing. Try this program to see how it works:

10 ' Demo of one-time line feeds

20 LPRINT "LINE NUMBER 1."

30 LPRINT "LINE NUMBER 2.";

40 ' One-time line feed

50 LPRINT CHR$(27);“J*‘;CHR$(lOO);

60 LPRINT "LINE NUMBER 3."

70 LPRINT "LINE NUMBER 4."

Here is what your printer will produce:

LINE NUMBER 1.

LINE NUMBER 2.

LINE NUMBER 3.

LINE NUMBER 4.
