The DPI refers to 'dots per inch' and indicates the quality of an image produced by an inkjet printer. What DPI should I look for in a small printer? A thermal printer will heat the paper according to the desired image, causing the picture to show up. Thermal printing, like zink, uses specialized paper rather than ink cartridges to deliver its results. This means it's potentially better for the environment, too. Instead, all color required is embedded in the paper, making it popular for instant mobile printers.

Zink is short for 'zero ink' and refers to a type of printing that requires no ink cartridges whatsoever. It works by putting tiny drops of ink onto the page at a rate indicated by the DPI. Inkjet is the most popular printing technology and probably the one you're most familiar with. Throughout this guide, you will have seen mention of various print technologies, including inkjet, zink, and thermal. Inkjet vs zink vs thermal - which one is best?
