The topic of computer recognition and entry of alphanumeric information has been known for approximately 30 years. Today, it is still vital, because the problems related to it have not found satisfactory solution. For example, the existing automatic reading devices require special fonts, like OCR-A, OCR-B, CMC-7, E13B, etc.The complete solution of the problem demands a reading system, capable of inputting letters, signs, numerals of arbitrary fonts and height from manuscripts and books. This problem is very complex and very hard to solve. A step towards finding a more general solution is the proposed factorization method for preliminary processing of printed text to be entered in a computer. It makes possible the recognition of letters and signs of different fonts and sizes.
