HP printer ink cartridges

The Hewlett Packard Company commonly known as HP is the world's largest information technology corporation and is most known for their computer printers and personal computers.

HP was founded in 1939 as a manufacturer of test and measurement instruments by Bill Hewlett and Dave Packard in a garage in Palo Alto, United States. Their first product was a precision audio oscillator, the Model 200A which became a low cost alternative to similar more expensive products in the industry. This and other inovations led to HP being recognized in later years as the symbolic founder of Silicon Valley but it would not be until 1966 that HP became involved in computers with the HP 2100 series of minicomputers and the world's first personal computer in 1968 called the Hewlett-Packard 9100A. It wasn't until 1984 that HP started building what they are now know famous worldwide for, their inkjet and laser printers.

HP supply a library of different types of inkjet printers used in homes and offices across the globe and although there are many different inkjet printers they all serve a certain type of user whether it be the home office user printing a few times a week to the office desk user printing many times a day. HP build their inkjet printers as an evolution of the previous model it succeeds rather than a replacement to it and because of this certain HP ink cartridges are compatible in a wide variety of inkjet printers rather than one cartridge for one specific printer. The most popular HP ink cartridge is the Hewlett Packard 51645A (or HP No.45) which can sit in a wide range of different HP printers. Closely followed by the 51645A is the popular combination of Hewlett Packard C6656A (or HP No.56) a black inkjet cartridge that works with the colour inkjet cartridge Hewlett Packard C6657A (or HP No.57) to go into many different home and office inkjet printers around the world.
