Ink cartridges have revolutionised written communications. Time and labour saving are just two of the assets of today's ink cartridge. This is one small demonstration of the way the pace of life has picked up, to the point of not having time to hand write anything. Many people still extol the virtues of the written word, particularly older people who truly appreciate receiving a letter from a friend or relative.

Communication was more of a concern than speed before the invention of the ink cartridge. The human race have always had this built in need to leave their mark on the world, to communicate their life story and pass on useful information.

Cave men were not the Neanderthals people think, simply concerned with hunting, grunting and reproducing. They coped with every-day life just as we do but with different priorities. In a bid to leave their mark and not be forgotten, they used sharp implements to etch their memories on cave walls.

Clay tablets were developed later on to make information transportable, so much easier than lugging your cave around with you. Caveman etchings consisted of a series of pictures that any onlookers could understand and the first alphabet that was written left to right was invented by the Greeks in 400BC, all in upper case due to the rudimentary nature of writing implements fashioned from bone, ivory or metal.

They used these first 'pens' to mark wax coated tablets that were hinged together 'book' style, in order for them to close and protect the contents. I'm sure the Greeks would have appreciated the ease of ink cartridges but at least they were able to condense their communications with the first text messages without the need for pictures.
