HP PCL5 打印机打印语法(HP PCL5 printer grammar)

可以实现stringgrid的直接打印功能，经过应用很好(Can stringgrid direct print functionality, a good application)

题目：打印出杨辉三角形（要求打印出10行题目：输入3个数a,b,c，按大小顺序输出。 题目：输入数组，最大的与第一个元素交换，最小的与最后一个元素交换，输出数组。 题目：有n个整数，使其前面各数顺序向后移m个位置，最后m个数变成最前面的m个数 题目：编写一个函数，输入n为偶数时，调用函数求1/2+1/4+...+1/n,当输入n为奇数时，调用函数1/1+1/3+...+1/n(Topic: Print out the Triangle (10 lines required to print out the Title: Enter the 3 numbers a, b, c, according to the order of output. Title: input array, the largest exchange with the first element, the smallest and the last element of the exchange, output array. Topic: There are n integers, to move back in front of the order m of the number of positions, finally becoming the foremost m m the number of number of topics: write a function, the input n is even, the call function evaluation 1/2+1/4+...+ 1/n, when the input n is odd, call the function 1/1+1/3+...+ 1/n)

说明：  热敏打印机的控制程序，用keil编译，can通信(Thermal printer control program)

条码生成技术源码，可以方便的生成各类型条码!经测试完全可以达到效果！(Barcode generator technology source code, you can easily generate various types of barcode! Tested can achieve the desired effect!)

利用QT控制打印机打印图片。（将图片放入QT的窗口中，打印窗口）(Use QT to control printer to print pictures. (put the picture in the window of the QT, print the window))

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.)

用来显示对应数字的条形码。共6种码制，可以选择打印大小，打印位置，也可以打印预览，不过暂时还不具备连接打印机打印功能，这个可以自己添加上去。(Used to display the corresponding bar code numbers. A total of six kinds of system code, you can choose print size and print position, you can print preview, but not yet connected with a printer function, this can add up.)

本程序用于DP-48A1达普内嵌式打印机打印二维码使用，内包含打印指令详细注释以及自行编程了集汉字、字符串、变量的二维码打印函数，可以方便使用。(This procedure for DP-48A1 da dimensional code embedded printer use, and contains detailed notes, and self print instruction program a two-dimensional code printing function set characters, strings, variables, you can easily use.)

js实现部分打印,本实例实现只打印设定好的div中的内容,而div以外的内容将不被打印(js to achieve part of the print, the print setting a good example to achieve only the contents of the div, but outside the content div will not be printed)
