Windows 7 has been specifically designed to be able to use Vista drivers, so you won't have any problems in any case. In fact on most hardware makers' sites, they seem to be offering the identical drivers for both Win7 & Vista. Clearly if HP understood the situation they could just rebadge their existing Vista drivers, but that's what they are like about drivers. I'll never buy another of their products after they refused to write Vista drivers for an extremely expensive, top-of-the-range scanner that was 18 months old
