Capture of Print Event

Question

Good afternoon,

I would like to know how to capture the print event using c#.

Example: the user clicks on the print option of the application he is using (Word, outlook etc...) and instead of calling a printer would open a form, which I will develop.

Because I want to process the information, record it in a bank and send that print to a server.

Thank you

I believe this is what you seek Findfirstprinterchangenotification Function

Syntax C++:

HANDLE FindFirstPrinterChangeNotification(
  _In_      HANDLE hPrinter,
  DWORD fdwFilter,
  DWORD fdwOptions,
  _In_opt_  LPVOID pPrinterNotifyOptions
);

Use of the DLL:

[DllImport("winspool.drv",
    EntryPoint = "FindFirstPrinterChangeNotification",
    ...)]

An example of use:

Monitor Jobs in a Printer Queue (.NET)
