接收串口打印机的指令和数据，源代码中包括了大部分指令的编程方法(Serial printer instruction and data)

打印功能模仿，和模拟打印机差不多的东西，不是自己编写的。(Print function to imitate, and simulation similar printer, not something I have written.)

字号与尺寸对照表，便于进行自动打印预览时查询字体大小以方便安排打印和排版(Font size table, easy to query the font size to facilitate arrangements for printing and automatic print preview typesetting)

说明：  开发语言C#，读取Excel中的数据，然后进行打印。标签大小可在源码中设置。(The development language C # reads the data in Excel and prints it. The label size can be set in the source code.)

该系统应具有以下功能： （1） I：初始化（Initialization）。从终端读入字符集大小n，以及n个字符和n个权值，建立哈夫曼树，并将它存于文件hfmTree中。 （2） E：编码（Encoding）。利用已建好的哈夫曼树（如不在内存，则从文件hfmTree中读入），对文件ToBeTran中的正文进行编码，然后将结果存入文件CodeFile中。 （3） D：译码（Decoding）。利用已建好的哈夫曼树将文件CodeFile中的代码进行译码，结果存入文件TextFile中。 （4） P：打印代码文件（Print）。将文件CodeFile以紧凑格式显示在终端上，每行50个代码。同时将此字符形式的编码文件写入文件CodePrin中。 （5） T：打印哈夫曼树（Tree printing）。将已在 中的哈夫曼树以直观的方式（树或凹入表形式）显示在终端上，同时将此字符形式的哈夫曼树写入文件TreePrint中。 (The system should have the following features: (1) I: initialization (Initialization). Read from the terminal character set size n, and n and n characters right value, establishes a Huffman tree, and save it in the file hfmTree in. (2) E: encoding (Encoding). Has been built using the Huffman tree (if not in memory, reads from the file hfmTree), the text of the document ToBeTran encoded, and then putting the result in the CodeFile file. (3) D: decoding (Decoding). Huffman tree has been built using the file CodeFile the code will be decoded, the result is stored in the file TextFile. (4) P: Printing code files (Print). CodeFile in a compact format the document displayed on the terminal, one per line 50 code. While this character in the form of written documents CodePrin encoded file in. (5) T: Print Huffman tree (Tree printing). Would have been in the Huffman tree in an intuitive way (tree or recessed table form) displayed on the terminal, but this form of characters written to the file )

打印控件 winform 编程时很好用的一款打印类库，操作简单方便(Print control, WinForm programming with a good print class library, easy to operate)

prim算法,输出最小生成树,时间复杂度Nlog(n)(prim algorithm)

该方法是Java语言从web后台进行调用打印机的例子(print method is used to applying the web project,this is a example)

HP1150/1160等系列的打印机 并口驱动程序 打印机语言是PCL5e (HP1150/1160 series parallel port printer driver PCL5e printer language is)

对FastReport通过调用Excel表格作为数据库演示单选打印及连续打印的例子。(Excel spreadsheet for FastReport by calling the radio as the database demo examples of printing and continuous printing.)
