7 months ago from , Product designer @ Zooppa

Hello guys, today i was fascinated by the font of the new printing calculator of my colleague this one: http://www.staples.co.uk/content/images/product/GenesisExtraLarge/09/98/asset.230998.jpg

Other than the ticking of printing that drive me crazy i was impressed of the font printed for calculus on paper.

I found in internet some images of the font but i don't know what font is http://www.casio-intl.com/media/calc/printing/miniprinter/img03.jpg

Can you give an hint? Thank you
