Have a problem with secure print on Mac Only.

The checkbox in the driver are marked to SecurePrint only. I have checked that it's written correctly to the PPD used, here the Secure Print are set to "True"

Problem:

If you print a document (regardless of type) with "Command+P" the secure print function works.

But if you drag the document (regardless of type) to the desktop printer or if you use the print button in word, the Secure Print are bypassed and it just prints the document ??

Data:

Mac OS 10.6.8 , 3.1.1 A4 driver. Minolta BizHum 280C....
