Although it would have absolutely beaten the hardware to death, did anyone ever try to write a graphics driver for daisy wheel printers that would use the period symbol to painstakingly construct a graphical image, using micro-step platen and printhead movements?
Due to the speed limitations of the printhead solenoid, such an image would likely have taken 10 times longer to produce than on a 9-pin dot matrix printer, and there is the possibility of damaging the period symbol by over-flexing the wheel support arm. It would be prohibitively expensive with single-use carbon ribbons, and might damage looped fabric ribbons.
But... was it possible and did anyone ever do this?
