SW1-1
Set this switch to OFF if you want to use the print buffer.
This switch controls the 2K-byte print buffer. When it is OFF
the buffer is used. This means information coming into the print-
er from the computer can be stored in the buffer until it is ready
to be processed, permitting the computer to operate more
efficiently.
When the switch is ON the buffer is disabled.
SW1-2
This switch is not used. It should always be OFF.
SW1-3
Set this switch to ON to add a line feed.
Some computers automatically cause the printer to advance
the paper one line each time a carriage return signal is received.
Others do not provide a line feed. Set this switch according to
which type of computer you have. If your computer provides the
automatic line feed, this switch should be OFF. If it does not
provide the line feed, the switch should be ON.
The user’s manual for your computer will tell you whether or
not this line feed is automatically performed. You’ll also know
when you start to print something out using your computer (but
not the printer self-test).
If you get double spacing when you want single spacing, this
means both the computer and the printer are providing a line
feed. Turn SW1-3 OFF.
If the second line overprints the first, neither the printer nor
the computer is supplying a line feed. Therefore, turn SWl-3 ON.
SW1-4
This switch is used with a special optional ROM (read only
memory) that attaches to the interface. The manual that comes
with this ROM explains how this switch should be set. If your
interface does not have the optional ROM, keep SW1-4 in the
OFF position.
