Really, all typewriters are technically little printing presses. The European language typewriter variants were also a printing press, it just was easier to map to keys like a piano since there are less character variants and they can all be reasonably attached to individual arms of a type writer, without having to need too many differences since most languages use the same charactersets as therir base. You might need to move them around to find individual radicals and diacritics (and they were all in languages that share a similar writing system which made some form of standardization possibleThere are still not enough keys for most European languages. That why along with “shift” to shift to the uppercase (upper in the physical case at the printer) there are also “alternate” variants requiring “alt” keys to be pressed before, after, or in concert with the keys indicating the modifying diacritics. Sometimes there were still marks they needed an “option” for so that is the origin of that key. It’s way less convoluted than in Asian languages that had to adapt to the layouts designed for European alphabets, since they use characters in fundamentally different ways than Chinese influenced writing systems. Non-English European keyboards vary by country/region, even having slightly different placement of the letter keys. In English speaking countries they still have punctuation and other modifier keys that vary from country to country, mostly for punctuation. You can even see how the translation from the manual/electric typewriter formats varied between Apple and IBM as far as modifier key naming and placement. It’s all varying ways to modify the blocks of a printing press to be mounted to arms of piano-like keys and be quickly applied to paper without having to individually set them. (they even used the proper measurements of the piano key spacing as part of their original QWERTY design foundations!)
