HOOK EnumPrinters——hide the other printers

Question

I want control the printers list, make it just show my printer.

I try to hook the EnumPrinters of winspool.drv global by the open source Mhook library, but it just effective in my Demo and the WPS office，noneffective in the Application of Windows such as Notepad.exe、IE。

And I discover my hook is effective in Notepad and IE, but it still could show all the printers even if I just return my printer in the EnumPrinters。

Is there other method to enumerate the printers after the EnumPrinters in Notepad.exe ？ 

Who can help me? thank you very much.

Hi,

How did you write the hook code? Do you mean that when you hook EnumPrinters, you can get the speficied printer in your demo but get all the available printers in Notepad and IE? If like this, how about tring to use GetPrinter function instead of EnumPrinters, which retrieves information about a specified printer.

I am also stuck with this problem for a while.

There are two dll prncache and prnfldr which are server and client. The server fills the cache. and notepad and IE picks up the list from there.

But the problem remains the same the server also uses EnumPrinters but that does not work.
