I just invented the 1D Printer. It is amazing.
You can't draw/print anything in 1D, because any line/dot you put on paper would have 3 dimensions, no matter how tiny they may be. (the ink trail has thickness too, hence 3d).
Which is the reason it was so easy! I just had to invent something that draws nothing, cus drawing in 1 Dimension is rather.. Hard.
Well maybe if you manage to draw strings... But. Whatever.
