ning out of continuous paper.

Your printer has the ability to print right to the bottom of the sheet. You can disable the paper-out detector so that it doesn’t 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 looked at are in the following table.

nBackspace, delete, and cancel text

Backspace (CHR$@)) “backs up” the print head so that you can print two characters right on top of each other. Each time your printer receives a backspace it moves the print head 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.
