Core Viewpoint - The article emphasizes the importance of the spirit of scientists, highlighting the legacy of Wang Xuan, a pioneer in Chinese printing technology, and his contributions to the field of computer science and laser typesetting. Group 1: Contributions to Printing Technology - Wang Xuan is recognized as the inventor of Chinese character information processing and laser typesetting technology, marking a significant revolution in China's printing industry after the invention of movable type printing by Bi Sheng [1][4]. - The "748 Project" initiated in 1974 aimed to develop a Chinese character information processing system, with Wang Xuan focusing on the advanced fourth-generation laser typesetting system [2][3]. Group 2: Innovations and Breakthroughs - Wang Xuan faced skepticism regarding his ability to develop a fourth-generation machine, particularly due to the challenge of storing vast amounts of Chinese character information in limited computer memory [3]. - He developed a unique "contour plus parameters" compression technique, which allowed for the storage of Chinese characters in a computer, significantly reducing the required memory [3]. Group 3: Impact on the Industry - By 1985, the Economic Daily became the first newspaper to adopt laser typesetting, leading to a rapid transition in the industry where 99% of newspapers and 90% of publishers abandoned traditional lead typesetting within five years [4]. - The introduction of color laser typesetting in 1992 marked a milestone, with the Science and Technology Daily publishing the first color newspaper produced using this technology [4]. Group 4: Legacy and Inspiration - Wang Xuan's approach combined scientific innovation with a commitment to national service, embodying the spirit of dedication and mentorship [4][5]. - His legacy encourages future generations to surpass his achievements and continue advancing technology in the field [5].
