Hi,

 

I've tried everything I can think of but I'm unable to get OpenPrinter API to work in my BasicMsi

prototype BOOL SETUPAPI.OpenPrinterW(
 WSTRING, //_In_   LPTSTR pPrinterName,
 NUMBER,//_Out_  LPHANDLE phPrinter,
 WPOINTER//_In_   LPPRINTER_DEFAULTS pDefault
);

try
	OpenPrinterW(szDriverName, Printer, NULL);
	
	
catch
	Err = GetLastError();
	SprintfBox (INFORMATION, "L862Error","Error occured: %i\n\n%s\n\n%s", Err.Number, Err.Description, Err.LastDllError); 
	
endcatch;

I always get a -2147219709 returned, I've also tried using OpenPrinterA and OpenPrinter but same error everytime.

 

Does anyone have any idea's as to what I may be doing wrong?
