Get the printing data from the Client
Posted on 2009-04-07
How to capture (in the client) the data being printed or atleast the window screen snap?. The main objective is to get the data before it could get spooled. Can it be done through MFC?

You could get a screenshot into a CBitmap. But is difficult to retrieve any data from a bitmap.
You also could (try to) hook into a print dialog but the data actually sent to a printer maybe graphical data as well as text data, it even could be raster points if you have no luck.
No, capturing printing data is not really a good method (beside you only want to prevent from printing).
