Re: print size?

I think that it also depends on what it is that the photograph is all about. A  solid color for example I think could be printed larger than one full of fine detail. Also, it depends on what the person’s criterion of “quality” is. Some people are pickier than  others. And of course, viewing distance … factors that have their roots in the film era! Methinks!

RIPs (raster image processing) can be  hardware or software and can vary based on use - RIPs exist for a variety of purposes, you'd need to look at a photographic RIP.  Software based RIPs can be quite simple but often expensive .. hardware rips even more so, except that printers themselves have RIPs onboard that often can do the job surprisingly well.

The prinetr it's self will apply the algorythms and fuzzy logic required to upsize the image and produce the best image it can without pixellation.
