     Beginning in the 1990s, we owned our first DOT matrix printer. DOT matrix   printers were like typewriters where they had an ink ribbon that would press onto the paper. It was loud and a very heavy machine that used only a particular type of paper that folded into sheets behind the printer. I guess for the 1990s, it was pretty good. In the year 2000, our family had an ESPON inkjet printer. At that point, printers were still connecting via separate printer serial ports that required their own dedicated cable. The ESPON inkjet printer at that time was terrible. It was loud, unreliable, consumed way too much ink, and had printer jams every other print job.  I made a vow never to buy another ESPON printer ever again. I’m sure the printers are better now, but it brings back bad memories.
     I started to look for another printer ranging from $100 to $300 along with the $100 replacement cartridges. Nothing really impressed me since I thought it was inefficient for any business to own a $300 to $500 inkjet printer and then purchase $100 cartridges every month. Color laser printers were of course too expensive to purchase or maintain.

    In 2014, I came across HP’s Office-jet Pro X476/X576 printer. It was one of the most versatile printers I had ever seen or used. The most attractive aspect was its cost efficiency. HP’s Office-jet Pro X476/X576 currently runs at $500+ and to replace the ink cartridges it’s $500 for all the black and color cartridges. This may seem expensive, but out of those cartridges I was able to print with laser–comparable printing speeds with around 9,000 black/white pages and around 6,000 color pages. A year after purchase with a normal inkjet printer one would spend around $1600 on printing supplies (printer included) . The HP’s Officejet Pro X476/X576 printer would save $600 every year owned because of HP’s breakthrough new inkjet printing technology.
     Some of the features of this printer are pages that are water and smear resistant, and highlighter friendly. This printer that performs two sided scanning, print, fax, and copies allows you to archive documents to the cloud for easy searching when you are at the printer with a USB drive. This HP printer supports Airprint and still be able to print without being on the same network. It also efficiently prints and scans two-sided documents. You can print professional-quality color with up to twice the speed and half the cost of color laser printers.
     The HP Office-jet Pro X476/X576 is one of the most economical printers for small and large businesses. This is result of HP PageWide technology. PageWide Technology is different from normal inkjet technology. There are 40,000 nozzles on each of the stationary ink print cartridges that are the width of the page. This makes the prints whisper quiet compared to other inkjet printers.

      HP’s PageWide Technology moves the ink differently than LaserJet printers. Instead of powders in a cartridge, this technology uses liquids to deliver ink onto the paper. When you first print, an electrical pulse lasting a micro-second heats a resistor that fills it with ink. A layer of ink then vaporizes to form a bubble that expands to propel  6 picoliter drops onto the paper. What happens when one of those tiny nozzles malfunctions? Surprisingly, HP PageWide technology constantly checks the performance of all 40,000 nozzles. Like other inkjet printers it calibrates itself so that when there is a faulty nozzle it makes a substitution. HP has created another breakthrough called Backscatter Drop Detection (BDD). This includes optics and photodectors along with analog and digital signal processing. The BDD works by detecting the light that is backscattered or reflected by a drop passing through a light beam. This allows the HP to calibrate and test hundreds of nozzles per second. HP’s Thermal Inkjet technology allows for both active and passive nozzle substitutions.
     This HP printer is innovative, economical, efficient, quiet, and recommended for any large or small businesses.
