Inkjet printers, along with laser printers, are one of the two most common types of printers available today. Quite often they are significantly smaller in size and load capacity than their laser counterparts, this in turn makes them far cheaper and a far better solution as a desktop device for infrequent usage.
The inkjet works by literally transfering ink directly to the page in coordination with the digital message that is delivered from the computer itself. The image is plotted across the page and transfered in quick horizontal motions across the page. With a colour inkjet this will be done using the four basic colours, with variations created by combining the primaries (blue, yellow and red) along with black.
Depending on the quality of the image that you require as well as the capabilities of the printer itself, you are able to create reasonably clear images with a reasonable dpi (dots per inch). As with all printers though the quality is determined by the clarity of the colour and the compactness of the dots. As a newer version of the dot matrix printer, for which the dots were larger and often more visible thus ruining much of the definition of images there is a similar principle at work, just with an updated standard of quality and accuracy.
Unlike a laser printer, which uses a toner cartridge filled with a coloured powder, the inkjet has standard liquid ink. This is finely distributed in the predetermined pattern on a page in order to create the image. This is an exacting process, with the size of the dot and the gap between each one being microscopic in size. As an inkjet quickly moves across the page it leaves the ink dots in its wake. As you may appreciate, this isn t always a quick process. A full A4 page full of colour and text will take upwards of 15 seconds on many models, although this will of course vary.
One of the criticisms of an inkjet is that there are often streaks or lines across the page. This is primarily caused by the motion by which the ink is transfered to the page. Better quality printers will reduce this, in fact many are almost entirely invisible to the naked eye. Another issue is with the drying time. As there is actual liquid ink used in the process of generating an image, it does take a fair amount of time to become usable. This can become an issue when putting together multi page presentations and is always a factor when it comes to choosing the right printer for any job.
Despite the complexities of the processes that it goes through each and every day, the inkjet is a stunningly simple piece of machinery. They have been used in homes and offices throughout the world for more than two decades. Their cost effectiveness has made them a highly accessible piece of equipment and their continued resilience has ensured that they remain a firm favourite.
Unfortunately an inkjet really isn t cut out for doing larger jobs, especially on a continued basis. This is why they have never been a regular feature in larger offices and have usually been overlooked in favour of the laser printer in such instances. However, despite the relative speed issues, it still remains a very cheap, accessible option that has been embraced by homes and office desktops everywhere. The inkjet printer is constantly evolving, with new features and specifications becoming available all the time. But despite all these changes, all these innovations, it still works in a very simple dot formation using conventional liquid ink.
