ClosePrinter Reference in C#, VB.NET and VB6


Visual Basic 6 definition
Declare Function ClosePrinter Lib "winspool.drv" (ByVal hPrinter As Long) As Long

Visual Basic .NET definition
Declare Function ClosePrinter Lib "winspool.drv" (ByVal hPrinter As Integer) As Integer

C# definition
[DllImport("winspool.drv")] public static extern int ClosePrinter(int hPrinter)


ClosePrinter closes a printer which had been previously opened by OpenPrinter. After this function closes the printer, the handle to the printer obviously can no longer be used, even if the function fails.

Return Value

If successful, the function returns a non-zero value. If an error occured, the function returns zero (use GetLastError to get the error code).
