What is the name of this font used in this picture?
Not "Typewriter" like, but like a Dymo Labelmaker. One possibility is Impact Label. Others include Carbon 14, Dimeotype, LabelGunTape, and Punch Label. There are others, such as DYMO (dafont.com) that don't have the distinctive serif'ed /I in your sample.
