单位有一台打印机，win10无法安装驱动。只能通过XP打印文件。

根据这个需求，只需将XP的一个目录共享，然后写一个程序监控目录新增加的文档，来操作打印机自动打印。

这段代码用到了目录监控、com操作word接口、线程信号来完成需求。
path变量是监控的目录地址，我这里使用的是c:\printTemp，日志目录为c:\printLog，这个需要更改一下。

import win.ui;
/*DSG{{*/
var winform = win.form(text="打印";right=589;bottom=349;parent=...)
winform.add(
editChange={cls="edit";left=23;top=21;right=564;bottom=322;db=1;dl=1;dr=1;dt=1;edge=1;hscroll=1;multiline=1;vscroll=1;z=1}
)
