摘要
A word processor includes a work station having a keyboard and a display device, a main unit for forming a text file in accordance with input commands entered by the keyboard, an external memory unit for storing the text file, a standardized character memory for storing dot patterns of characters having standardized style, a modified character memory for storing dot patterns of characters having modified style, and a printer for printing out a document in accordance with the text file. When a plurality of documents to be delivered to different addresses are formed in accordance with the same text file, different characters in respective documents are replaced by modified characters to form text files having different modified characters. Then the plurality of documents are printed in accordance with respective text files having different modified characters, so that these documents can be distinguished from one another.
