You'll have to call them. But for now I'm using Vista 64 drivers when I can.
I am buying new computer that will have Windows 7 64 bit preinstalled. My current computer has Windows XP loaded and I share the printer with my laptop that has Windows Vista 32 bit installed. The printer came with XP driver and I downloaded the Vista driver and both computers will print by using a switch between them. My question will Dell write a Windows 7 driver for this printer or will I need to try to use the Vista 64 bit driver thats on the Dell web site?
As before thanks for any replies Swijo
