Abstract
In some printers, a printhead receives a stream of a printing fluid from an intermediate tank
which is supplied with ink from a supply tank. In such a system, printing fluid can be fed from
the intermediate tank to the printhead using an air pump to pressurize the supply of ink by
pressurizing the air volume inside the tank.
