An object of the present disclosure is to provide a technique capable of appropriately ordering an ink bottle. One embodiment of the present disclosure is a printing apparatus that includes: an ink tank that stores ink supplied from an ink bottle; and a head to which ink is supplied from the ink tank, and the printing apparatus includes a transmission unit configured to transmit status information in which at least information relating to an ink remaining amount within the ink tank is included to a server and order processing of a new ink bottle is performed based on an ink consumption amount of the ink bottle.

A method of detecting a level of printable fluid in a container includes, with at least one sensing location on a die in thermal contact with the printable fluid in the container, sensing a voltage of a capacitor over time as current from the capacitor leaks through a field effect transistor (FET). The FET and capacitor are associated with the sensing location. The method may further include, based on the voltage of the capacitor over time and a threshold voltage, determining whether the printable fluid is present at the at least one sensing location.

An example ink tank includes an ink tank and a cap assembly attached to the ink tank with a preloaded hinge. The hinge rotates the cap assembly from a closed position to an open position when the cap assembly is unlatched. The cap assembly includes a bung to seal the ink tank during a partial rotation of the cap assembly when the cap assembly is unlatched. The ink tank also includes spring-loaded linkage connected to a valve in the ink tank. An effector extending from the cap assembly engages the spring-loaded linkage when the cap assembly is latched and disengages from the spring-loaded linkage after the cap assembly is unlatched. The spring-loaded linkage opens the valve when engaged with the effector, and closes the valve when disengaged from the effector, while the bung maintains a tank seal until the internal valve is closed.

An example system includes an imaging device and a consumable storage unit. The imaging device includes at least one consumable used in operation of the imaging device and a controller. The consumable storage unit includes at least one cavity to store a replacement consumable therein. The replacement consumable is inaccessible for use in operation of the imaging device. The controller is communicatively coupled to the consumable storage unit to receive a signal indicative of presence or absence of replacement consumable in the consumable storage unit.

An example support for a fluid container is described, comprising a bracket comprising a U-shaped cross section and a strain gauge attached on a web of the U-shaped cross section of the bracket, between a mounting portion for attaching the bracket to a printing apparatus and a bearing portion for attaching a fluid container to the bracket. An example method for determining the amount of fluid in a container is also described, comprising measuring with a strain gauge a strain occurring at the web of a U-shaped bracket, the U-shaped bracket having a wing for attachment to a printing apparatus and a wing for carrying a fluid container; and determining the amount of fluid in the fluid container based on the measured strain.
