JetJaneMono is a very large family of sans-serif faces which are mono-spaced, as are typefaces used in typewriters and cheap computer printers. There are three weights in the extended family: Thin, Plain, and Bold. In addition there is an italics version in the same weights which is close to the "book" version, with some differences in lower-case letters and symbols. Finally, there is an all-caps version in which the lower-case letters have been replaced with scaled versions of the upper-case letters.
JetJane is meant to give the look and feel of the typefaces used in dot-matrix printers, though it is not modeled on any particular one. It is best used at lower point sizes, such as 10, 11, or 12.
