Draino is for grease. And I don't really like it for that either.Would draino or something be worth a try?
You may have something in the trapway that is catching the paper. A closet auger is good for that. If it's a solid object in there, it may need to be pushed out from the other side by removing the bowl and augering from the exit.
Sometimes, you have take a five gallon bucket and try pouring into the bowl and see if that breaks anything loose. That only works though if it's paper in the bowl. It won't do much if there is a main line blockage.
If other fixtures in the bathroom are draining fine, then it may be, just the bowl.
