Changing Line Spacing | Star Micronics Delta instruction

44	Delta User’s Manual

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:
