Ink refills use bottled ink to refill empty inkjet cartridges.  Ink refills are generally much cheaper than new inkjet cartridges.  Ink refills are also clean and easy to use.  In addition, ink refills usually provide good results.  Most inkjet cartridges are capable of being refilled with ink refills.

An inkjet printer is any printer that uses printer ink cartridges to place extremely small droplets of ink onto paper to create an image.   

• The dots from the printer ink cartridges are extremely small (usually between 50 and 60 microns in diameter), so small that they are tinier than the diameter of a human hair (70 microns)!
    
• The printer ink cartridges dots are positioned very precisely, with resolutions of up to 1440x720 dots per inch (dpi).
    
• The dots from the printer ink cartridges can have different colors combined together to create photo-quality images.
  

Inkjet printers and inkjet cartridges are fairly inexpensive. They cost less than a typical black-and-white laser printer, and much less than a color laser printer. Inkjet cartridges are much less expensive than toner cartridges.
