From: Jason Harrison on 15 Dec 2009 19:03 I'd like to know how to determine if an installed printer driver is WHQL-signed. How do I do this? I tried looking at the Printer Server properties and examining the properties of the drivers but couldn't find any signing information for any of the DLLs. This included HP printers who'd I expect would have pass WHQL testing. -Jason
From: Kerem Gümrükcü on 16 Dec 2009 00:14 Hi Jason, assuming you know the path of the driver (if not have a look at the devcon sample and how to list driver files for a device), you can work like this: [Example C Program: Verifying the Signature of a PE File] http://msdn.microsoft.com/en-us/library/aa382384%28VS.85%29.aspx Have a look at all the Cryptography and Security functions, they can be of big help, also the examples,... Good luck!

Find the printer in the Device Manager. Then click on properties and "driver details". Drivers passed WHQL will be signed with the MS signature. (Note: you need to be logged on as admin, otherwise the signature details may be not displayed correctly). --pa
