when to end one line and start another.

There are two codes that are used to end one line and start another. They are carriage return (CHR$(13)) and line feed (CHR$(lO)). The codes are simple, but their action is a little confus- ing (especially with BASIC). Carriage return is the easiest. Each time that the printer receives a CHR$(13) it returns the print head to the left margin. It does not advance the paper (if DIP switch 2-4 is off; see below).

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 2-4 on so that Delta will add the line feed for you. When you have DIP switch 2-4 on 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 spaces when it should single space, then you probably need to turn DIP switch 2-4 off.

Changing Line Spacing

When you turn Delta on the line spacing is set to 6 lines per inch (or 8 lines per inch if DIP switch l-5is off). This is fine for most printing applications, but sometimes you may want some- thing different. Delta makes it easy to set the line spacing to what- ever value you want.

Try this program to see how easy it is to change the line spat-

ing:
