You need a fast dry ink and good paper. But yes with usual supplies, it can be problematic. My kid enjoys writing with fountain pain but her furnitures are given by school and they hand out a lot of printedpaper to fill..So no luck.

The problem I find is fountain pens are awesome in the dragging motion but really don't do well with a pushing motion. Writing left handed in a LTR world means you're constantly pushing the nib while a right hander drags the nib.
