A method for interfacing an HP26 ink-jet cartridge to a computing resource is presented. A general purpose interface will allow new and custom application of ink-jet printing technology. Drive characteristics of the HP26 cartridge are captured and a driver board subsequently developed that permits direct control of nozzle firing timing and properties. Reproduction of the drive signal and satisfactory ink deposition is validated. The application of ink-jet printing technology to bioprinting research is targeted in this work.
