 Daisy wheel printers are capable of producing simplified graphics in the form of ASCII art.As daisy wheel elements are made of plastic to keep mass and manufacturing costs low, using the period character for graphics would cause unacceptably rapid wear, so plastic elements are offered with a metal insert in this position that lasts much longer.Consideration was also given to optimising graphic printing by changing the glyphs on the daisy wheel to a set that would be able to print all the required bitmap combinations more quickly, without requiring an impact for every single dot.
