操作网页以包含水印

Question

我使用仅适用于Mozilla Firefox的Web应用程序。

一个特定的任务生成一个页面来打印要邮寄的信件。

打印完信后，我的同事应该为邮局的品牌加盖邮票，并手工写出邮件的发送日期。

有没有什么办法可以在打印之前操纵页面的显示以在HTML中包含一个带有图章图像的行？

任何想法？

非常感谢。

Answer 1

是否有任何理由需要通过autohotkey完成？如果您有权访问代码，则可以添加覆盖图章图像的打印样式表。

SmashingMagazine有a fantastic guide to print stylesheets：

从本质上讲，所有你需要做的就是添加到您现有的样式表：

@media print { 
    //css to add the stamp image overlay here 
} 

Answer 2

感谢您的反馈意见。

我想通了。

这是我的代码：

#NoEnv 
#Persistent 
#SingleInstance force 
SendMode Input 
SetWorkingDir %A_ScriptDir%
