Sometime back I purchased a Hermes typewriter that included some typed sheets, including this one for a typist position at a middle school in Cupertino or Sunnyvale, California. There’s no date on the document, but there are plenty of clues:

First clue: the doc describes a typing position
Other clues: ditto masters, mimeo, Xerox, Thermofax, Gestetner
1980s?

Wow, Thermofax. Ancient. I’m thinking 1960s due to calling the copier a Xerox as well as the other lost to new technology terms. Might me as new as the 1970s. I really doubt 80s since it is CA.
The company I where I worked had facilities in Cupertino, CA, and CA was much farther advanced than PA where our Corporate offices were.
For the longest time, whenever I wanted to make a copy, I’d say I was going to Xerox it. I’m not that old (Generation X), but it was a thing. This school certainly employed a lot of print technology.
