The GetDefaultPrinter function retrieves the printer name of the default printer for the current user on the local computer.
BOOL GetDefaultPrinter( _In_ LPTSTR pszBuffer, _Inout_ LPDWORD pcchBuffer );
A pointer to a buffer that receives a null-terminated character string containing the default printer name. If this parameter is NULL, the function fails and the variable pointed to by pcchBuffer returns the required buffer size, in characters.
pcchBuffer [in, out]
On input, specifies the size, in characters, of the pszBuffer buffer. On output, receives the size, in characters, of the printer name string, including the terminating null character.
If the function succeeds, the return value is a nonzero value and the variable pointed to by pcchBuffer contains the number of characters copied to the pszBuffer buffer, including the terminating null character.
If the function fails, the return value is zero.
|ERROR_INSUFFICIENT_BUFFER||The pszBuffer buffer is too small. The variable pointed to by pcchBuffer contains the required buffer size, in characters.|
|ERROR_FILE_NOT_FOUND||There is no default printer.|
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.
