Remarks
Note
This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.
Before an application calls the AddPrintProvidor function, all files required by the provider must be copied to the SYSTEM32 directory.
A provider added by AddPrintProvidor may be removed by calling DeletePrintProvidor.
