Abstract
An apparatus which prevents an increase in a print suspension time or the time required to print because of a remaining ink detection operation when there is a sufficient amount of remaining ink. At least one ink tank is monitored to determine if the remaining ink is less than a given amount. If the remaining ink in an ink tank is less than a given amount, printing is suspended and it is determined which ink tank has ink less than the given amount.
