Final answer:
The machine in question is a fax machine that sends printed material over the phone lines. Computers have significantly improved the fields of typesetting and printing by direct-to-plate technology and the use of precision-controlled laser printers in the xerographic process. Typesetting and printing have become more precise and efficient with the advent of computer technology.
Step-by-step explanation:
The subject described in the question is a fax machine, which is a device that converts printed words and graphics into electronic signals. These signals can then be transmitted over telephone lines and reassembled into their original form on the receiving end. The process is akin to the digital data transmission used in technologies such as cell phone conversations and television broadcasting, where information is converted into binary sequences for clearer transmission and efficient compression.
In terms of the impact on computerized typesetting and printing, computers have revolutionized these processes. For printing, computers can now output directly to printing plates, bypassing the older photographic methods. This advancement leads to more efficient and faster printing processes.
Furthermore, laser printers utilize the xerographic process to create high-quality images, employing precision-controlled laser light to produce an image on a photoconducting drum. These laser printers can process significant amounts of information, generating sophisticated letters or fonts.
The advent of computer technology has also affected the process of typesetting, the arrangement of text and graphics into a desired format, which goes hand-in-hand with the art of printing—applying ink to paper in the arranged design. Modern technology ensures both steps are highly precise and efficient.
