  • Patent number: 11889041
    Abstract: A printing system includes a company server and a printing apparatus. The printing apparatus is used in business-use printing and private-use printing. The printing apparatus includes: a printing section performing printing on a medium by using a printing agent; and a waste agent collecting section collecting as a waste agent, the portion of the printing agent that is consumed by the printing section but is discarded without being used in printing on the medium. The printing system includes a determination section and an estimation section. The determination section determines whether the printing agent as the waste agent is discarded in business-use printing or private-use printing. The estimation section estimates an amount of printing agent determined by the determination section to be discarded in business-use printing.

  • Patent number: 11745524
    Abstract: There are provided a medium support section that forms a support surface that supports a medium before feeding; a feeding roller that sends out the medium supported by the medium support section in a feeding direction; and an apparatus main body, the medium support section is configured to switch between a stored state of being stored in the apparatus main body and a protruding state, the protruding state being a state where protrudes from a first side surface which is one of side surfaces that form a periphery of the apparatus main body, and in the protruding state of the medium support section, a downstream end of the support surface in the feeding direction is at a position close to a second side surface, which is a side surface opposite to the first side surface, between the first side surface and the second side surface.

  • Patent number: 8596735
    Abstract: Ejection of ink is prohibited when a count value of an amount of ink supplied from an ink tank to an ejection head reaches a value limit. An image is displayed to prompt an operator of the printing apparatus to confirm the amount of ink in the ink tank. When the ink remains, the count value of the amount of ink is returned only by a given amount by the selection of the operator. Thus, since the ink in the ink tank is sufficiently consumed and then the ink can be supplemented, all of the ink in an ink bottle can be supplemented. As a consequence, it is possible to prevent the ink remaining in the ink bottle from deteriorating and prevent the remaining ink from being supplemented.

  • Patent number: 8485622
    Abstract: If an ink amount supplied from an ink tank to an ejection head reaches a predetermined limit value, ink ejection is not permitted. If initialization data are input and the input initialization data are appropriate, a count value of the ink amount is initialized, and the ink ejection is started again. In addition, the initialization data which is input once and determined to be appropriate is determined to be inappropriate thereafter. By doing so, although ink of which the property and state are inappropriate is used for the refilling, since appropriate initialization data may not be input, it is possible to avoid the inappropriate ink from being used for the refilling.
