Epson Ink Tank System All In One, Ink Tank System Printer and Scanner L355

There are several types of printing technologies :

Inkjet printers uses liquid ink sprayed through nozzles onto the paper, and laser printers use a toner cartridge (filled with fine powder) and a heated fuser for printing.Each technology has its own importance.

Inkjet Printer : In the inkjet printing technology, the print head has several tiny nozzles. The copy from an inkjet printer needs a little time to dry. Adequate drying time is especially important if the hard copy contains large sections of solid black or dark color.The advantage of using an inkjet printer is that they give an excellent color output.

An ink tank system in printers continuously supplies ink to a comparatively small inkjet print head. It increases the print capacity. Ink in the tank will lasts for a long time and it is refillable. How long the ink will last depends on how heavy the usage of the printer is for the user. The general warranty that companies offer for the Ink Tank system is for a period of one year or in a range of 25000 to 30000 pages.

A multi-function printer is a type that performs multiple tasks alongwith printing such as scanning, sending fax, photo copy, automatic document feeding etc.

On demand inkjet print method is a broad classification of inkjet printing technology where drops are ejected from the print head only when required and saves ink. This method improves productivity, reliability, flexibility and enables ad-hoc printing.

On-demand ink jet: In this on demand inkjet process, the print cartridges consist of a series of tiny chambers, each containing a heater that ejects the droplet from a chamber.

Borderless printing is a printing technique that makes a printer print an image without any margin or other border. Borderless printing is mainly used for printing a photo without any border, printing an image which needs multiple pages of paper like billboard or big photo, or printing a full page template.

A nozzle is a hole smaller than a human hair found on the print head of a print cartridge. Each nozzle produces millions of ink droplets used in creating the images and text generated by your printer.

A scanner's optical resolution is determined by how many pixels it can actually see. In a typical flatbed scanner it uses scanning head with 300 sensors per inch, so it can sample 300 dots per inch (dpi) in one direction.

Contact Image Sensors (CIS) are image sensors used in flatbed scanners almost in direct contact with the object to be scanned. CIS are popular due to its less cost and easy maintenance.

Bit depth is the scanner's ability to accurately analyze and reproduce the full color spectrum of the scanned information. This increased bit depth processing helps in improving the ability to obtain detail from the darker areas of an image.

48-bit internal, 24-bit external means that the scanner (48 bits - internal) performs the internal processing to select the best possible colors from the available shades or (palette) of colors and outputs only in 24-bit color (24 bits -external).

This is a method that feeds paper through a printer. Friction-feed printers make use a plastic or rubber rollers to squeeze a sheet of paper and pull it through the printer.
