1) Conventional inkjet-type processes on high quality paper are probably not
archival. Most will probably fade relatively rapidly; just put one in a
bright and sunny spot for a while. I think they are working on making this
better.
2) Newer dye sublimation printers are becoming available. They are generally
of "archival" quality and the have the advantage of printing continuous tone
images (instead of small, close dots). Right now, these are pretty
expensive, around $1000 and up. Check the manufacturers and they should be
publishing specifications.
3) For archival purposes, you can always get a photographic print from
selected (or all) of your digital images. See services like Seattle
Filmworks or Print@Kodak and others.
4) There are two format issues concerning digital photos: the storage media
(CD, Zip, floppy, tape, etc.) and the file format specification (jpg, tif,
sid, etc.). Both of these will change in the future. Media will increase in
capacity and change in recording techniques. Compression will improve,
yielding smaller and smaller images. There probably isn't anything you can
do about these changes except go with the flow.
