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 2-6 off so that your printer
will add the line feed for you. When you have DIP switch 2-6 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 spaces when it should
single space, then you probably need to turn DIP switch 2-6 on.

n Changing the line spacing
When you turn your printer on the line spacing is set to 6 lines
per inch (or 8 lines per inch if DIP switch 2-8 is off). 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.
Try this program to see how easy it is to change the line spac-
