In the old days, when I finished a manuscript, I had to fire up the Daisy Wheel
printer and spend the next four or five hours in paper-jam hell while we printed a hard copy of the manuscript.
In order to access the web you have to have a username and password and I have used the same one since I swapped my old daisy wheel
typewriter (or tripe writer as Dai used to call it when he was little) for a computer in the 90s.
You change elevation up front by depressing the spring-loaded blade with any highly specialized finger of your choice, then rotating the notched daisy wheel
under it to move the blade higher or lower using any pointed thing that'll fit in the space (pen tip, tiny screwdriver, toothpick, etc.).
