Windows 7: Printer driver digital signatures

Printer driver digital signatures

I had installed an HP DeskJet F4280 All-in-One printer and recently discovered that one of the printer drivers has no digital signature.

---> C:\WINDOWS\system32\difxapi.dll

All the rest of them were listed with full signatures. Any ideas as what to do in regards to this issue? All help would be greatly appreciated.
