Importance of Tape Data Cartridges for Modern Information Systems

Information is pretty much everything in the world of business. Large corporations maintain their edge through competition by gathering, sorting, and storing relevant information. By prioritizing information systems, businesses open up a lot of possibilities to succeed. The information rich system will then become a visible guide to enhance internal operations, marketing campaigns and so much more. Information is essential for a business to succeed but it comes at a cost. Modern information systems are relatively expensive. However, this can be remedied by making use of tape data cartridges.

Ink Cartridges 101

The ink cartridge of an inkjet printer is a peripheral that makes printing possible. It is the vessel loaded into the printer that contains ink. Depending on the manufacturer, a cartridge may contain four to six ink tanks of different colors. Some ink cartridges are outfitted with print heads like those of HP or Hewlett Packard while others have it built into the printer. With this arrangement, users are assured of stunning prints because of the presence of a new print head with every replacement ink cartridge.

Evolution of Laser Printers

evolution of laser printers

A laser printer is a type of digital printing machine that uses laser beams to produce printed output. The precise correlated interaction of the imaging drum, fuser and rollers is responsible for the systematic transfer of image on paper. Electrical potential is applied on each phase of the printing process.

Printing Resolution
Resolution determines the quality of the printouts. The higher the resolution, the better the resultant output. Early models could only deliver on the average 300 dpi (dots per inch), both for horizontal and vertical resolutions. However, recent developments have been really encouraging as resolutions had moved up to the 1200 dpi threshold. OEMs worked at enhancing output resolution which resulted to the tremendous improvement in print quality.

Printing Speed
As printing technologies progressed, print speeds improved tremendously as well. It used to be that only monochrome printers can be expected to deliver the much bruited printing speed. Now even color laser printers can reach the 50 ppm (pages per minute) level. Thanks to the single pass printing technology, laser printing has reached enviable heights in speed.

Printing Technologies
Laser printers employ a laser beam delivered by the scanner assembly to create text and images. The laser scanner assembly delivers the digital image of the document in the form of regularly sequenced dots. The dots are written on the surface of the photosensitive drum.

Basically, the entire printing process will depend on varying electrical charges. As toner is positively charged it will literally cling to the negatively charged dots etched by the scanner. Since paper inherently has a higher negative charge, the formed image simply transfers to the paper surface as it comes in contact with the drum. Thereafter, the image on paper moves into the fuser. Remember the entire printing process occurs at blinding speeds.
