„Want to learn about inkjet printer technology, and apply it with a robot or by waving an inkjet nozzle over a piece of paper? Parallax, Hewlett-Packard Specialty Printing Systems, and Matt Gilliland have combined to produce this unique kit. The hardware and documentation are designed around HP’s Thermal Inkjet 1.0 technology. Using the Parallax Serial Inkjet Printer board, your microcontroller sends a string of serial data which is printed as 1/8” tall characters. Waving the inkjet cartridge over a piece of paper or mounting it on a Boe-Bot produces print-quality text in the font of your choice!“
