What you should know about laser color printer
Transferring language onto an archivable medium has always been an interest of human civilization. From the time of cave writing to scribes and through the invention of the printing press, finding ways to communicate in a stable manner that can be transferred across hands and generations has been long sought. With the invention of the printing press and subsequent advances in computing and inks, technology gradually opened up the doors to a laser color printer for your own personal computer.
Initially, these advances were typified by dot matrix printers and later by certain forms of inkjet printers. But, perhaps the most stable, highest quality workhorse of the personal printing revolution has been the laser printer. Laser printing is now accessible to almost all consumers as a feasible, cost-effective option by purchasing a home laser color printer.
A more recent development has been the significant reduction in price without significant loss of performance in laser color printers. With these advances, the laser color printer may soon be considered the de facto standard for the personal computer enthusiast. The laser printing process is quite ingenious, and is often distinguished into seven steps, including raster image processing, charging, exposing, developing, transferring, fusing, and cleaning.
The remarkable aspect of this is that these seven steps are accomplished within the span of milliseconds. In many cases, newer printer models even merge the seven essential steps of laser printing to accelerate the process. Rather than using only black ink, colored laser printers typically use three colored toners in addition to black, namely cyan, magenta and yellow. As a result of this diversity, color laser printers also typically have more than one laser assembly, sometimes one for each toner cartridge, but perhaps more often one for the color inks and a separate assembly for the black toner.
Partly as a result of having multiple physical assemblies and partly because of the different physical locations of the color sources, color printing is vulnerable to registration errors, defined as the very slight misalignments that can occur between colors. Registrations errors can degrade print quality, leading to color fringing, blurring, and streaking, especially at the edges or boundaries of regions covered by the color toner.
One strategy to improve registration accuracy and reduce such blemishes is for the printer to use a “transfer belt.” Transfer belts are large rotating belts that are passed in front of the toner cartridges to receive toner. The toner layers are combined on the belt and then transferred onto the paper or other printing medium at once, producing a better result.
Thus, advancing in printing technology have brought us all the way from cave writing to today’s personal laser color printer. While a laser color printer may cost more per page than standard black printers.
