Star Micronics NX-10 user manual 1CHRW

stop the printer. This will allow you to print to the end of the sheet, and even beyond if you are not careful. The codes to con- trol the paper-out detector, along with the other codes that we have just learned are in the following table.

nBackspace, delete, and cancel text

Backspace (CHR$@)) “backs up” the printhead so that you can print two characters right on top of each other. Each time your printer receives a backspace it moves the printhead one character to the left, instead of to the right. You can strike over multiple letters by sending more than one backspace code.

Delete (CHR$(127)) also “backs up” one character, but then it “erases” the previous character (it’s erased from your printer’s buffer, not from the paper).

Cancel text (CHR$(24)) deletes all the text in the print buffer; that is, in the line before the delete text command. Since your printer prints one line of text at a time, only that line will be deleted.

The following program shows how these codes works.

10 LPRINT "BACKSPACE DOES NOT";

20 LPRINT CHR$(8>;CHR$(8);CHR$(8);

30 LPRINT ~I=== WORK"

40 LPRINT "DELETE DOES NOT";

50 LPRINT CHR$(127);CHR$(127);CHR$(l27);
