python 全自动打印网站

项目介绍

• win32print可以打开打印机，进行打印操作，以及一些高级打印机设置。
• flask作为一个轻量级的web框架，很适合做一个无人打印自助的前端技术。
• 使用花生壳进行内网穿透
• 界面使用bootstrap稍加美化
• 可以实现远程提交docx文件到本地电脑，调动打印机打印文件

花生壳内网穿透

成功配置内网穿透

创建一个保存打印文件的目录

运行项目

网站映射成功，通过外网网址进入网站可以看见网站内容

说明

打印机高级选项设置

	attributes['pDevMode'].Duplex = int(chooseDuplex)           # 1单面 2长边装订双面 3短边装订双面
    attributes['pDevMode'].Orientation = 2                       #纵向打印（暂时无法横向打印）
    attributes['pDevMode'].Color = int(chooseColor)             # 0彩色 1黑白
    attributes['pDevMode'].Copies = int(chooseCopies)           #份数

一个简单的表格是这么创建的：

类变量	Value
Duplex	1单面 2长边装订双面 3短边装订双面
Orientation	未知，我怎么设置都只能纵向打印
Color	0彩色 1黑白
Copies	份数
