That .pdf puts some light on the problem, but it really applies to resin-coated "RC" papers like Premium Luster, Glossy, and other such papers with plastic-like surfaces.
Not only can those papers fog the glass if framed too early, if dry or adhesive mounted too early they are likely to develop bubbles either immediately or within a few weeks. Also these papers are somewhat pinched until the ink is completely dry, if you hinge mount them too early they will develop ripple as they dry. I have personally experienced each of these problems in painful ways.
Canvas and rag paper inkjet media are different beasts and seem to dry a little faster, although 3 days is definitely not too long.
I disagree with the "blotter" drying method described in pdf, it is best to hang the prints up for at least 3 days before framing, although 1 week is better. Aside from being too much work, the blotter method is prone to damage prints by abrasion, embedding dirt particles, etc. As for blotting canvas, I wouldn't even consider it since it would almost certainly pull off pieces of the image.
The only accelerated drying method that works for me is to tape a print up on the inside of a sun lighted window for several hours, sunlight hitting the back of the print directly. About 8 hours of that is enough. Don't tape it up all around, just hinge it at the top so any solvent on the back can escape.
Bottom line, if somebody gives you an inkjet print ask them how long ago it was printed. A wet inkjet print doesn't necessarily look wet. If you can smell solvents when sniffing the print, it's probably still wet. Dry RC prints will lay flat. If you place it on a very flat surface like a piece of glass and you can see ripple on the surface or along the edges, it's probably still wet.
