KONICA MINOLTA Di152 Windows 7 and Windows 8 driver

I had to share a KONICA MINOLTA Di152 printer.
It was necessary that Windows 7 desktops also could print to it.
The Di152 hasn't have Windows 7 or Windows 8 driver, only for Windows 2000/XP.
However the Di152 operates with Di470 Windows 7 or Windows 8 driver as well.
It is true by default Di470 printer is not visible in the list, you must press a Windows Update to update the printers list, and after that appears Di470 printer, and it can be installed.

Another solution: if the Di152 appears as "unknown device" try to "update driver" (it was suggestion in a comment on my hungarian blog).
