Installing printer drivers programmatically ?

I most install printer drivers on a PC without the user having to use the Installation wizard of Windows.

I looked at MSDN documentation and found that I need to user the AddPrinterDrivers function of the API... The function return the 'success' value (1). What is strange is that the driver are not installed at all, if I go in the Add Printer wizard, the printer is not listed... Have you any idea on how to install printer drivers? Also, is there a way to do this by just specifying a .INF file?

Thanks
