Development Of Printers Over The Years.

Over the years printers have improved massively, they've gone from being wind up printers where you have to physically print your own things out to this day having 3D printers meaning you can form 3D objects via scanning.

The printer in this image is from years ago, you can see that the whole layout is much different than the newer ones, everything is done manually and by hand.this next image is of the brand new 3D printer, it can make and form 2D objects into 3D. 
This is massively different to the older printers, including the graphics, the first image of the old print would have very poor graphics and nothing would be clear and interesting but the new one has tons of graphics, its interesting
and does things no other printer can..

This printer is more more eye catching than the old one, its almost as big but does something completely different.

Graphics.

Graphics plays a big part in technology, with good graphics it makes what you're watching much more interesting and clear to see.the way graphics changes is very clear,
in this photo the graphics on both the characters have changed and you can see the most recent one looks the best and this photo only shows up to 2008 meaning that even now in 2013 the graphics are even better.

Not many people always understand the effect of good graphics, it's only when they watch something with better graphics than they're use to they become more interested and realize the effect that graphics has on games, television program's, computers etc.
a good comparison to look at is the difference between vector and bitmap, this photo clearly shows the difference between the two.
The vector image is more
clear and appealing to look at
than the bitmap/raster image.
