Printers have changed are lives a lot, and it very simpler. But the catch is whenever one thinks about publishing the first thing that comes to anybody’s mind is an Inkjet Printer. People have simply associated printing with Inkjet Printers, as they have seen them all around. They are the best in printing. They are the cheapest. They make the least sound. They are very fast in the price range they are available. They are cheaper than the cheapest laser black & white printer available in the market. They can be used for a long run. They don’t get heated very fast.
The only reason these printers are sold at lower price as, one has to buy the ink of the same printer manufacture, as they make it incompatible to other inks. So they make their profits their, in the supplies of the inks. People have all the knowledge of the printer they own, but ask them how it works from the inside and they go mum.
So here’s a simple understanding of an Inkjet Printer:
• There are two types of printers, impacting and Non-Impacting printers. Impacting printers are those who are in direct contact with the paper as Dot Matrix Printers. Instead of metal needles in the Dot Matrix printers, an Inkjet Printer utilizes hundreds of tiny guns to fire dots of ink at the paper. The letters are made of dots only, but the dots are very small and tiny that you cannot see them.
• And Inkjet, Laser printers come in the Non-impacting range, as they transfer ink via nozzles. Then further in the Inkjet range there are two types of printers one which uses bubble printing technology and other piezoelectric technology. In the Bubble Technology, heating resistors are used to heat the ink and create a bubble drop t transferred to the paper from the nozzle. They create less noise, but the dots a re large.
• In the piezoelectric technology, small crystals are placed in the nozzle. Theses crystals vibrate under the effect of electric currents. This enables the ink to be pushed out and the excess ink is drawn in. in this way the dots created are very small. Thus increasing the resolution of the printed document or image. An average inkjet can print 600 dots per inch, which is ten times better than Dot Matrix printers.
• The inkjet nozzles build up a whole page of text or graphics from millions of separate dots. Controlled by your computer, the ink cartridge scans from left to right across the page and back again, depositing ink as it goes. Each time it reaches the end of a line, the paper advances forward slightly so the next line can be printed. They are very economical to buy, and make very less noise. They are so very economical to print documents as the ink is not very expensive. But if you heavy printing usage, you may burn wholes into your pockets.
These printers working on Drop on Demand (DoD) technology are very smart and are widely used in Households, Offices for daily usage of printing.
