Many people, especially graduate students from engineering, have guessed back in the late fifties the great important and influence of computer technology for the daily activities of the twenty first century men; it is one of the reasons why today we have dominant names such as the ones already mentioned.

Like so many other electronic manufactures, HP specializes in designing, developing and marketing software and network hardware, computer components, parts and computer-related devices and devices for data storage. We trace its beginnings back in the late 1939, when the HP company was established in the garage of Dave Packard, located in California, Palo Alto, with a capital investment of 538 US dollars; with many representative in almost every country of the world, its headquarter still remains in Palo Alto.

As I’ve stated before, HP specializes in creating computers but also computer-related products such as the printers, scanners or the all-in-ones. These electronic devices have different features depending on purpose they were invented for; for example, the HP printers can be simple with single-function laser jet or inkjet or they can be all-in-ones, and that means that a single electronic device incorporates all features specific to a scanner, an HP color/ black and white laser or inkjet printer, fax, etc.

On the official homepage of HP you will see all the available HP laser color printers, inkjet printers or all-in-ones categorized depending on the usage, being designed especially for business or professionals, for graphic arts or for at home and for students; depending on the brand, being business jet, photosmart, office jet or laser jet, with wires or a wireless network.

One of the cheapest HP color laser printers has to be the HP LaserJet Pro P1102w Printer, with a wireless 802.11 b/g networking, with speeds up to 19 pages per minute and an ultra-compact and quiet design and energy efficient.

One of the most expensive color laser jet HP printers has to be the HP Color LaserJet CP6015dn Printer with a wide format, speeds up to 40 pages per minute in black or color, a ready network and an automatic two-sided printing and an expandable 600-sheet input capacity.

The HP Color LaserJet CP1518ni Printer prints image-rich documents in an approximate time of 8 color pages per minute and 12 in black. This printer also has a compact and stylish design with a built-in networking but also card slots and tools for creating marketing materials.

The HP Color LaserJet CP 3525dn printer has speeds up to 30 pages per minute, in color and black, a built-in gigabit networking and a two-sided automatic printing, being ideal for marketing materials; the HP Color LaserJet CP3525n Printer prints almost 22 pages per minute, in black and color, with a 350-sheet input capacity and a Fast Ethernet embedded print server.

The HP Color LaserJet CP4525dn Printer has an automatic two-sided printing with speeds up to 42 pages per minute in color and black and an already available network; the same features can be found at the HP LaserJet P4515n printer, with the sole exception about the speed which is up to 62 pages per minute and a 500-sheet input tray and automatic two-sided printing bundle.

One of the great benefits of using such devices, especially the internet and the mobile phones, is that the communication at far distances no longer seems to be a problem while the instant sharing of information allowed people to become aware of the events that happen all around the world, from the closest to the farthest location point.

In fact, technology became just like a new religion; without it, life would become unbearable and we certainly know that we don’t want to return to the old days when, as an example, the physically dangerous jobs were done only manually.
