I am perplexed as to why Dell does not make a driver for the AIO Printer 964 that is compatible with Windows 8. I do not have Windows 10. I searched for the driver and every other driver exists for every other printer. This seems very odd indeed.
The Dell 964 printer is an older Dell Printer. The printer was made for Dell by Lexmark. Lexmark got out of the printer business, so no new drivers will be made for this printer. You should be able to install the Vista drivers in the Vista SP2 Compatibility mode
Please follow the instructions below and see if the printer installs.
Download the Vista 32-bit drivers for Windows 7, 8, 8.1 and 10 32-bit or the Vista 64-bit drivers for Windows 7, 8, 8.1 and 10 64-bit. Install the Vista drivers in the Vista Compatibility mode you’ll get a message, the printer is not connected. Connect the printer at this time (powered on).
