Daisy Wheel Printer
An almost obsolete type of printer.
A daisy wheel printer has a small plastic 'wheel' with spokes running out from its centre. At the end of each spoke there is a flat part that has a raised alphanumeric character shape.
The way it works is that the wheel is rotated to bring a character up against an ink-ribbon. Then a tiny hammer pushes the shape on to the ribbon causing a letter or number to appear on the paper behind the ribbon.
Daisy wheel printers are noisy and slow compared to modern ink-jet and laser printers.
