It has been evident for several years that printer manufacturers make far more revenue for their company profits from replacement cartridge sales than they can ever conceive of accumulating from printer sales - The possible figures are staggering - and particularly extreme with low cost entry level printers. When one realises that cartridges contain ink and that over the years manufacturers have progressively been reducing the quantity of the ink fill that they supply in cartridges (with very few exceptions) - It means that customers pay more per print with newer printers than they did with older models.|
This is the case with Hewlett Packard and Lexmark where cartridges have been made progressively smaller in size. e.g. Just a few years back HP sold cartridge for home user inkjets which contained 40mL of ink - Latest HP offerings as little as 5mL per cartridge!!
The only serious way to save cash with HP Lexmark Dell and a few others is to refill the cartridge with ink - This is basic recycling and is the cheapest way to run printers as it is replacing the raw commodity used - Ink. HP & Lexmark attach the print head onto their cartridges so this is another reason to recycle as purchasing a new cartridge means that the print head is replaced for a new one - Not a bad thing but - not always essential as the empty cartridge has a reusable printhead - refilling these type of cartridges avoids the need to always be replacing this expensive part.
Epson and Canon put the printhead into the printer as a re-usable part and make the part which contains the ink a much simpler "Ink tank" - These are much cheaper to produce / copy and many clone cartridges have appeared over the years some as good as the original for quality of prints.
These compatible cartridges have been increasingly undermining Epson's market share of the replacement inkjet cartridge market.
It is an indication of
how much the after market sales of ink cartridges matters to Epson
profits, that this manufacturer has been raising actions in the UK High
Court citing infringement of Intellectual Property and Patents which
Epson hold on their Ink Tanks. In the UK none of five (or more?) actions (or threat of action) has been tested in the courts as in the first 3 cases we know of the companies written to and threatened with High Court Action have backed down - settled "Out of Court" and agreed with Epson not to continue selling compatible cartridges which infringe. The UK ink cartridge
manufacturer Jettec (whose cartridges we sell on
www.proprint.co.uk also settled
with Epson - Jettec have their own patents on their cartridges and this
was the first instance of a cartridge manufacturer reaching an amicable
settlement never to have ceased production and continuing with production
of Epson compatibles to this day.
