We use a Hp z6200 with spinflow and in the past week it will print fine for 2 to 3 jobs then when it prints another job it will print then stop in the middle of the job and have to restart the computer and printer to get it working again. then i have to repeat it multi times. Does it need a firmware update. Spinflow is up to date. look in back of the plotter and i cant reset the memory or nic card because its built in the motherboard.
