In HTML there is the TT tag which displays text using the "teletype font", though some assume this also means typewriter. It is sometimes assumed that typewriter "fonts" or typefaces are all the same, or very similar in any case. Something like the Courier New font used in this blog.
In fact every manufacturer tended to have their own typeface, even individual typewriter models could have a unique typeface. Below are a few examples from some of the machines in my collection. They are all pretty similar (except maybe the Tippa's) but all were different in size, width and strength.
