美国巴特耳公司正研制一种高速激光印刷机和识别包裹邮区代号的电子阅读器,以帮助设备自动化,降低处理大小不一的信件和包裹的成本。在为美国邮局进行了二十个月研究论证的这一系统中,包裹标签将首先进行人工阅读,其邮区代号则输入计算机。计算机操纵一台机器在透明的标签上喷印上激光打印的仪表邮区代号的条码。那些条码只能在特殊光照下看到,可经光学扫
U.S. Butter Company is developing a high-speed laser printer and an e-reader that recognizes the parcel zip code to help automate equipment and reduce the cost of processing mail and parcels of varying sizes. In a system that has been researched and validated for the United States Post Office for 20 months, the parcel label will be first read manually and its zip code will be entered into the computer. The computer manipulates a machine to print the bar code of the laser-printed meter postcode on a transparent label. Those barcodes can only be seen under special lighting and can be optically scanned
