There are certain situations where print quality isn't the highest priority. When printing primarily simple text, for example, extremely high-quality prints often aren't necessary. As long as the text is readable, that may suffice.
However, there are plenty of circumstances that require incredibly detailed graphics, ultra-crisp lines and other precise prints. When those considerations are important, thermal inkjet printing is the better choice.
The thermal inkjet printing process is a bit slower than the alternative. At first, this may seem like a drawback. However, in reality, the extra speed of continuous inkjet printing requires sacrificing quite a bit of quality to save that time.
Thermal inkjet printing technology achieves better images by going a little slower to increase precision. When it comes to printing, you can't rush quality.
