An ink jet printer includes pumped-forced circulation of ink through the printer head and a nozzle cap which together eliminate gas from the ink supply and overcome ink stagnation which adversely affect printing quality. Ink from a tank circulates through the printer head and returns to the tank while the nozzles are capped. A brief flow of ink from the nozzles completes a purging of the head prior to printing.
