Digital Typesetters – Scanning & Laser Technology makes life better and easier is a true line with true meaning. For example, digital computers and digital typesetters increase the work output in less time. The digital computer, in combination with the high resolution cathode ray tube (CRT) and laser, is revolutionizing the communications industry, because digital computers have no mechanical parts and are entirely composed of electronic components, they set and process type at speeds never thought possible. In addition, the text type from digital typesetters has now been developed to rival the quality of photo-type. Knowledge of digital computer functions is critical to an understanding of digital typesetting. A digital computer is an electronic device that uses electricity to process information. It can perform repetitive logical and arithmetic operations and store the results of those operations in memory. A computer system is composed of hardware software, and firm

Bar Code A bar code is a code in a printed form which can be easily read by a machine connected to the computer. The information or data is encoded using the width of printed bars, the width of spaces between bars, and the relative positions of wide or narrow bars and spaces (i.e. a unique wide or narrow combination of black and white bars). You can easily see this kind of bar codes on all imported goods, journals and books. Almost every field use this technology for their products. These bar code are the most cost effective and least expensive way of encoding information since the bar code labels can be printed on plain paper, which the machine can easily read and encode the data or information.   Bar code symbologies are essentially alphabets in which different widths of bars and spaces are combined to form characters and ultimately, a message. Because there are many ways to arrange these bars and spaces (which are printed in a defined ratios), numerous symbol
