CodeSoft软件可以方便设计打印条形码,但如果要同时打印不同尺寸的条形码,就需要多台打印机。虽然CodeSoft软件上可以选择打印机,但只要在一个标签文件中选择了某一台打印机,则其他标签文件都会自动修改为这一台打印机。从而无法实现同时控制多台打印机打印的功能。本文通过CodeSoft控件设置打印机,从而实现一台电脑同时控制多台打印机打印的功能,满足了很多需要打印不同尺寸的场景需要。 相似文献

对方正书版文件转换PDF的7种方法从转换质量、效率和投入成本方面进行了比较,认为安装方正系列打印机后,直接在书版大样预览窗口输出PS文件后,再采用Adobe Acrobat转换为PDF文件,是目前比较符合期刊编辑部进行远程校阅的一种较经济、效率较高、转换质量较好的方法。 相似文献

“年年岁岁花相似,岁岁年年人不同。”刘希夷的这两句诗用来形容照片打印机市场是再合适不过了。去年,许多兼具相机和打印机生产能力的厂商将打印控制功能设计到了数字相机中,同时也推出了不少支持直接打印打印的照片打印机,这种数字相机直接控制打印机的模式被厂商称为“立拍立打”或“一拍直 相似文献

Word软件是一款功能强大的排版和绘图软件,但由于其输出功能较弱,不能直接输出激光照排常用的PS文件,限制了Word软件用于书刊的排版。随着功能强大、灵活易用的Adobe Acrobat 7.0 PRO软件的推出和PS打印机的日益推广,有效地解决了Word文档激光照排输出的难题。Word文档经过Adobe Acrobat 7.0 PRO软件的多次转化或经过PS打印机的打印功能均可生成用于激光照排的PS文件。笔者的实践证明,这些方法稳定可靠、简单易学,不但弥补了Word软件的输出弱项,而且为Word文档直接 相似文献

由于桌面型3D打印机是一种以数字模型文件为基础的累积制造技术,容易受到打印速度的影响降低打印机工作效率,传统的桌面型3D打印机采用单路固定数据传输和逐层打印的方式,增加了打印时间,导致打印速度慢的问题。提出基于频分多路复用(FDM)的桌面型3D打印机速度提升算法。分析了桌面型3D打印机的工作原理,设计桌面型3D打印机的喷墨控制模型,采用打印效率和打印速度对偶分析方法,融入频分多路复用(FDM)方法实现桌面型3D打印机的多目标集优化控制,并对速度量化指标进行评估,根据不同频率传送各路打印请求消息,实现打印速度提升。仿真实验表明,该技术能有效降低各路打印输入信号的干扰频谱,实现3D打印机的喷墨准确控制,大幅降低打印时间和内存开销,提高打印速度。 相似文献

CAS should stick to the principle of rendering service to, and giving impetus for, the development of China's science enterprise by making S&T innovations, said CAS President LU Yongxiang. The CAS president made the remarks in a recent talk to communicate the gist of the winter session of the Party's Leading-member Group at CAS, which was held from 7 to 11 January in Beijing. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
