) As Boolean

'Usage
 
Dim instance As IVirtualPrinterClient
Dim virtualPrinterName As String
Dim initialData() As Byte
Dim value As Boolean
 
value = instance.Startup(virtualPrinterName, initialData)

bool Startup( 
   String^ virtualPrinterName,
   array<byte>^ initialData
)

Parameters

virtualPrinterName: A System.String that represents the printer name.
initialData: Initialization data set by the server machine.

Return Value

returning false from this function will cause the cancellation of the print job.
