TIJ, the technology offered by Hewlett-Packard, prints best on porous and semi-porous substrates only. In addition, Norton said, TIJ excels in uptime/reliability, cleanliness, and ease of use. TIJ also has superior print quality, at print resolutions up to 600 x 600 dpi.

Piezo, while its quality is almost as good as TIJ's and while it prints on both porous and non-porous substrates, can be expensive. "The cost of replacing printheads is thousands of dollars, instead of $30 for a new HP printhead," Norton said.
