富土施乐DocuPrint CPl05b彩色打印机：高分辨率下的LED

LED打印和激光打印是当今数码打印成像的两大核心技术,而LED打印成像技术由于受到LED体积的限制,一直很难满足用户对于较高打印分辨率的需求。因此,我们以往在市场中见到的LED彩色激光打印机最高分辨率多为600dpi,但随着LED打印技术的发展,这种类型的彩色打印机在打印分辨率上有了新的变化。     

打印技术路线之争仍将继续

伴随着惠普公司推出第三代水平式一次成像技术,导致LED打印技术与激光打印技术的市场融合成为可能。但是,LED打印技术阵营与激光打印阵营就此偃旗息鼓却不太现实,打印技术路线之争仍将继续。这是众多打印市场分析人士的共识。以OKI为首的LED打印阵营与以     

LED打亮OKI

想获得快速、高质量的打印文档,也许有些用户会认为非激光打印机莫数了。而激光打印机通常体积较大,外型笨重,而且打印成本很高。有没有一种高效而总体成本又很划算的方案呢?也许OKI 公司的 LED 打印机值得你试一试。LED 打印机采用的是数字 LED 技术,与激光打印机采用的激光扫描技术相比,数字 LED 技术具有着一定优势。激光成像技术是由一束激光打到一个在旋转运动的多棱镜上,反射光再打到感光鼓上成像。由于打到感光鼓两侧的光会形成发散,因此可能会使两侧成像扭曲。而 LED 技术则是由与像素数相同的 LED 光源沿宽度方向排成一列,光直接打到感光鼓上成像。由于一束光形成一个像素,因此成像更为清晰,而且两端成像不会发生扭曲。同时由于没有运动

三项技术让激打更高效

顺应科技发展的脚步,激光打印机正被愈来愈多的人接受。而随着激光打印技术的成熟,针对不同用户群的各种激光打印机更是频频面世。诚然,激光打印机打印的文字及图像非常清晰,在输出品质上针式打印机无法与之抗衡。而其在节省时间、能源及成本控制方面的特性又为喷墨打印机难以企及。两相权衡,激光打印机成了更多重效率、注质量的商务人士的首选。 具体到激光打印技术的核心,其光扫描成像过程如下所述:全部数据信号串行传送给一个光发射     

从技术到未来分析LED打印机的优势

目前,市面上LED打印和激光打印是当今数码打印成像的两大核心技术,两者的打印原理基本是相同的,基本上都是采用电子照相打印方式,具体来说可以分为四个阶段,在感光鼓的周围有充电和曝光的阶段,另外还有显影和打印的阶段。其中,只有曝光部份区分了现在所谓LED和激光。在其他的地方是完全相同的。

记者胖丁报道9月16日 OKI推出了采用 LED 技术的 C5000系列激光彩色打印机。与普通激光打印机相比,LED 型的彩色打印机在打印过程中感光鼓可以方便地直线排列,省去了在普通激光打印机中常用的透镜等设备,使操作简洁化,打印速度高达黑白每分钟20     

Exceptional C or C with exceptions

C does not have exception handling facilities. Errors are handled by examining the value returned by each function and signals (conditions reported to the program) are handled by using library functions. These approaches lead to ad hoc error-handling techniques and can make programs hard to understand. Exceptional C, a superset of C, provides exception handling facilities. Exceptional C integrates the two techniques used by C programmers (i.e., status values and signals) to handle errors into one unified exception handling mechanism. In this paper, I review exception handling models, specify the criteria used for designing the exception handling facilities in Exceptional C, and then describe these facilities. I also illustrate the use of the exception handling facilities with examples.     

High-Fidelity C/C++ Code Transformation

As software systems become increasingly massive, the advantages of automated transformation tools are clearly evident. These tools allow the machine to both reason about and manipulate high-level source code. They enable off-loading of mundane and laborious programming tasks from human developer to machine, thereby reducing cost and development timeframes.Although there has been much academic work in software transformation, there still exists many hurdles in realising this technology in a commercial domain. From our own experience, there are two significant problems that must be addressed before transformation technology can be usefully applied in a commercial setting. These are: 1.) avoiding disruption of style (i.e. layout and commenting) and the introduction of any undesired modifications which occur as a side effect of the transformation process. 2.) correct handling of C preprocessing and the presentation of a semantically correct view of the program during transformation. Many existing automated transformation tools inherently disrupt style through the use of pretty printing and the need to perform preprocessing before any transformation. Some also require source to be modified so that it conforms to a subset of the grammar. In this paper we describe our own C/C++ transformation system, Proteus, that is able to meet the stringent criteria laid out by Lucent's own software developers.     

改进C/C++的预处理功能

预处理在C/C 中发挥着重要作用,然而这些预处理功能存在着一些缺陷,例如在头文件包含进来时,无法改变头文件中的内容;代码的重用性不高;大量重复代码等等。本文提出用一种高级配置语言XVCL(XML-basedVariantConfigura-tionLanguage)代替原来的预处理机制,来克服以上提出的问题。文件被组织为树形结构,并定义了利于提高重用性的变量作用域机制。文章通过一个实例来验证本文提出的方法的有效性。

(2) Correct automated handling of C preprocessing and the presentation of a semantically correct view of the program during transformation. Many existing automated transformation tools require source to be manually modified so that preprocessing constructs can be parsed. The real semantic of the program remains obscured resulting in the need for complicated analysis during transformation. Many systems also resort to pretty printing to generate transformed programs, which inherently disrupts coding style. In this paper we describe our own C/C++ transformation system, Proteus, that addresses both these issues. It has been tested on millions of lines of commercial C/C++ code and has been shown to meet the stringent criteria laid out by Lucent’s own software developers.     

C2C电子商务企业竞争力研究

伴随着互联网的发展,电子商务逐渐进入我们的经济生活中。作为网络经济的产物,电子商务企业与传统企业在竞争优势上存在巨大差异。面对着日益激烈的竞争,电子商务企业如何保持核心竞争力优势对企业的生存尤为重要。本文聚焦于C2C领域,并以淘宝网为例,尝试从企业核心竞争力的角度诠释电子商务企业与传统企业竞争优势的差异和竞争力培养的着力点。     

C/C++预处理分析与改进

通常的C/C 预处理器是一个宏处理器,在编译前自动地把源文件转换为编译器可识别的形式。传统的预处理方法基于文本行替换,没有考虑到具体的上下文环境。这种预处理机制在文件包含、宏作用域、头文件关系上存在着一些缺陷,会影响工程项目代码重用,降低程序的可维护性、可扩展性等。通过从分析c预处理器缺陷出发,并利用FOG[1]及其语言可以得到一种基于元变量和元函数的语法替换机制的解决方案。
