To-Do List

Issues

 * Thermal, piezo-electric or continuous?
 * Permanent print head (i.e. canon and epson printers have print heads that wil never need to be replaced for the usable lifespan of the printer)?
 * Disposable print head ( i.e. HP designjet large format printers have replaceable heads that need periodic replacement)?
 * Disposable print head and ink cartridge (i.e. most consumer HP ink jets printers replace ink resevoir with printhead as one unit)?
 * Solvent based ink or aqueous ink? the pigment suspension medium will possibly affect the choice of which print head technology will be used.
 * head cleaning: wiping, capping, suction.
