What I failed to mention in my previous post, is that reading page 5 post #81 alone was insufficient to comprehend in which way your experiences may or may not have been relevant. The context is -- unfortunately -- necessary.
However, having trundled through most of the thread seems to have revealed/confirmed a few things:
1) You can get close to having centered prints with CS3, but it's unclear what work-arounds you need to do with which printers and paper types -- there's a lack of documentation from Adobe. "Maximize" or "minimize", are they available always?
2) Backwards interoperability between CS3 and CS2 seems slightly shadier than CS2 to CS or v7, but it's unclear whether this happens when "maximize compatibility" is turned on or not.
3) There seems to be a misunderstanding about the meaning of "default" I.e.: fallback in case there are no other (sensible) settings; something you default to (Norwegian translators often confuse "default" with "standard", as the participants of the discussion apparently do too.)
4) CS3 is still in beta (i.e. is feature complete, but not essentially bug free), just like Lightroom. However, Adobe follows current "best" practice among software companies, and have substituted "beta" for "alpha" and "release" for "beta". (Okay, the former "best" practice was to substitute "release candidate" for "beta", but we've now obviously progressed beyond the need for "release candidates", or they're simply not publicly known.) Whether this is good or bad is a matter of personal preference. Given the features of CS3, I'm glad that the software is available rather than having to wait. Others may feel differently.
