In Engpsh, we call a "打字机" a "typewriter". The word "typewriter" comes from the combination of two words in Engpsh: "type" and "writer". "Type" refers to the individual letters, symbols, and numbers that are struck by the keys on the machine, while "writer" refers to the fact that the machine is used to produce written text.
Here are some example sentences using the word "typewriter" in Engpsh, along with their translations in Chinese:
I used to have a typewriter when I was younger, but now I just use a computer to type. (我小时候有一台打字机，但现在我只用电脑打字。)
My grandma still has her old typewriter, even though she hasn't used it in years. (我奶奶还有她的旧打字机，尽管她多年没用过了。)
I prefer the feel of typing on a typewriter over a computer keyboard. (我更喜欢在打字机上打字，而不是电脑键盘。)
