The term 'copier of old' can be described by two crossword solutions: SCRIBE (6 letters) and mimeo (5 letters). A SCRIBE is a person who copies documents by hand, usually in the form of manuscripts. This was a common practice before the invention of the printing press. Mimeo is a type of copying machine that was popular in the mid-20th century. It used a process called mimeography to produce copies of documents. Both scribes and mimeo machines were used to make copies of documents before the invention of modern photocopiers.
