Not hardly.
The bowl leaves the dishwasher via PR's hands, collecting her fingerprints on the way to the cupboard. A criminal wearing gloves (I know, a lot like the movies) removes the bowl from the cupboard and puts pineapple into it.
Fingerprints on the bowl hardly places PR with an alive and awake JBR. You're assuming that the fingerprints were left at the same time pineapple was fed to JBR.
An Intruder could also have worn orange sneakers, a red sweatshirt and a diaper. However, I don't have any proof for any of that, just like there is no proof an Intruder was in the house wearing gloves. Your speculation doesn't prove or disprove anything and neither does mine.
The facts are Patsy and Burke's prints were on the bowl and glass of tea and that the bowl had pineapple in it that matched the chemistry of the pineapple found in JonBenet's upper digestive tract.
