Hi daisysix –
Solid ink printers are different that ink jet and laser. Laser printers use electromagnetically charged toner particles to create the printed image. Most ink jet printers create the printed image by spraying water-based ink directly onto the paper.
Solid ink printers use resin and polymer-based inks – first melting the solid ink sticks, then spraying the molten ink onto a drum, before transferring the image to the page. Here are a few links that might be helpful if you want more details.

Thanks for asking about solid ink!
