批量打印ZwPldy

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

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))

说明：  grid++打印条码，特别好用，谁用了就知道了(Grid++ prints barcodes, which are very easy to use. Anyone who uses them knows.)

模拟字符方式（非GUI方式）打印 (Simulating character printing)

说明：  delphi获得打印机全部信息，注意不是打印队列的源码(delphi obtains the printer complete information, pays attention is not prints the formation the source code )

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)

一个打印出你好世界的c文件，非常简单！仅供参考！ (a file describes hello world )

实现带头结点的单向链表的创建、删除链表、插入结点等操作，并能实现年龄递增的两个单向链表合并一个链表，合并后的链表按年龄递减，可认为同名同年龄是同一个学生，每个学生在合并后的链表中仅出现一次。最后打印输出合并后的链表元素，验证结果的正确性(Take the lead node singly linked list to create, delete linked list, insert node operation, and age of increasing two-way linked list merge a linked list, combined linked list decreasing by age, with the same name in the same age a student, each student appears only once in the combined list. The final printout list elements after the merger, the correctness of the verification results)
