It may be that there is a difference in printer drivers.
Vista and windows 7 come with many printer drivers, but the drivers are
usually "basic" drivers, so it's often necessary to use
downloaded drivers from the OEM's web site to fully utilize the printer's
Then, you get into the application settings, printer driver settings(look
here first), and so forth.
Vista and windows 7 also have improved (more complex) "color management". If
not set up properly, it can cause problems as well.
You may have inadvertently set something (camera, windows, application,
printing options, photo file type, compression,etc.) that reduces the
quality of the printed photo.
Without knowing exactly how you go about printing photos, it's hard to give
you any specific advice.
In the years that I've used windows to print photos, major improvements have
occurred, notably with printer output quality and speed.
A confusion factor that also has arisen has to do with the "DPI" of a
printer versus the photo file's pixel count. They are NOT the same.
A printer with decent drivers can print a photo file in multiple sizes. This
means that the printer software can add or remove "dots" to make the photo
file "fit" to the proper dimensions. This obviously will have an effect on
printed quality. (And so on)
