What is a common term used to describe the symbol that is used on printers, photocopier and fax machines to start printing? It is square standing on one of its corners with a vertical line inside almost connecting the top and the bottom corner but with some space around. It usually appears on a big green button.
The only description I could find is at http://www.baddesigns.com/copier.html, calling it “the line in the diamond”. I was however unable to find any name whatsoever. Canon uses this symbol on some of its Pixma line printers (example), but only an icon is used to reference the button.
