What is it from? It looks a bit like a till receipt, in which case it will be something within the printer hardware rather than a digital font.

It's from a typed letter. At first I though it was probably from an old IBM Selectric but
it doesn't seem to be. It could well be a printer font. It looks, to me at least, like a familiar / common font but I haven't been able to find it. A bit annoying really 8-)
