A raster device is more expensive than a vector device and a raster device produces complete lines.
A raster device is an input device while a vector device is an output device
A raster device treats the output as a whole whilst a vector device treats the global output as being made up out of a number of different parts. So vector devices produce complete lines whilst raster devices produce images as a series of dots.
Raster devices are output devices while vector devices are input devices.

Because buffering makes the printer work faster
Because buffering frees the CPU to do other things while printing or accessing other i/o devices
Because buffering wastes less ink
Because buffering allows the printer to print in colour

A hardcopy is output whilst a softcopy is what we input.
A hardcopy is what we input whilst a softcopy is output.
A hardcopy is output which lasts for a short time only whilst a softcopy is permanent.
A hardcopy is permanent and tangible whilst a softcopy is not tangible and can be easily changed.
