GETTECHNOLOGY

The GETTECHNOLOGY printer escape function identifies the type of printer driver.

To perform this operation, call the ExtEscape function with the following parameters.

#define GETTECHNOLOGY  20

int ExtEscape(
  hdc,             // handle to device context (HDC)
  GETTECHNOLOGY,   // the escape function
  cbInput,         // size of input structure in bytes
  lpszInData,      // pointer to input data
  cbOutput,        // size of the output structure
  lpszOutData      // pointer to the output structure
);

Handle to the printer device context.

Specifies the size, in bytes, of the data pointed to by the lpszInData parameter.

Pointer to a buffer containing the input data.

Specifies the size, in bytes, of the data pointed to by the lpszOutData parameter.

Pointer to a buffer containing the output data.

If the function succeeds, the return value is greater than zero. If the function fails or is not supported, the return value is less than or equal to zero.

To get extended error information, call GetLastError.

• For non-XPSDrv printers: This escape reports on whether or not the driver is a Postscript driver.
• For XPSDrv printers: Reports on whether or not the driver is the Microsoft XPS Document Converter (MXDC). If it is, the escape returns the zero-terminated string “http://schemas.microsoft.com/xps/2005/06“.

• Windows NT/2000/XP/Vista: Included in Windows 2000 and later.
• Windows 95/98/Me: Unsupported.
