Line feed is more complicated. Each time the printer receives a CHR$(lO) it both advances the paper one line and returns the print head to the left margin, ready to start a new line.

Now to add a little confusion-most (but not all) versions of BASIC add a line feed (CHR$(lO)) to every carriage return (CHR$(13)) that they send. If your version of BASIC doesn’t do this, then you should turn DIP switch l-8 off so that your printer will add the line feed for you. When you have DIP switch l-8 off the printer will do the same thing when it receives a carriage return as it does when it receives a line feed.

If you find that your printer double spa-es when it should single space, then you probably need to turn DIP switch l-8 on.

nReverse line feeds

Your printer has a unique capability: it can move the paper up or down! Its unique tractor design allows the paper to be fed in either direction without jamming. This allows you to move around the page at will. You can use this feature to print several columns of text side by side, or print a graph and then move back up and insert descriptive legends. As you experiment you’re bound to come up with more uses!

The simplest form of reverse paper feeding is a reverse line feed. The code is (ESC)( LF), which causes the paper to move down (in effect, moving the printing up) one line. A “line” used in a reverse line feed is the same size as a line in a regular line feed (this is normally l/6 inch). When you change the line spac- ing (which you’ll read about next), you change it for both for- ward and reverse line feeds.

nChanging the line spacing

When you turn your printer on the line spacing is set to 6 lines

per inch. This is fine for most printing applications, but sometimes you may want something different. Your printer makes it easy to set the line spacing to whatever you want.
