Definitely an intersting idea, and it's quite smart to take plant cells as most of them are pluripotent anyways (the charactersitic that mammal cells only have as embryonic stem cells (and cancer cells)).
The point is that just printing them wont give them an environment that tells them what they should do and so nothing will happen. And just plotting seeds.... well in my opinion what you want sound more or less like a improved sewing machine.
Something else:
You could try to 3D print with quickly gelating hydrogels and include some bacteria for the first step. Thats not what you had in mind but it's a beginning.
