Abstract: In one example, method includes displaying an estimate of the number of pages that can be printed from a total amount of printing fluid including a printing fluid supply and a printing fluid reserve. The estimate is decremented in amounts of a first interval, in response to a first sensor signal indicating that the printing fluid supply is not empty. The estimate is decremented in amounts of a second interval that is smaller than the first interval, in response to a second sensor signal indicating that the printing fluid supply is empty.

Abstract: A replaceable printer component includes a memory device to store a tag encryption mask and data. The data is stored in a plurality of blocks of the memory device wherein each block is defined by a tag. The tag encryption mask indicates an encryption status of each block of the memory device defined by the tag. The replaceable printer component includes a communication link to communicatively link the memory device to a printer controller when the replaceable printer component is installed in a printing system. The tag encryption mask is stored within a header of the memory device. Each tag defines a type and a length of the data stored in the blocks.

Abstract: A replaceable printer component includes a memory and a communication link. The memory stores a tag encryption mask and data. The data is stored in a plurality of portions of the memory where each portion is defined by a tag. The tag encryption mask indicates an encryption status of each portion of the memory defined by a tag. The communication link is configured to communicatively link the memory to a printer controller when the replaceable printer component is installed in a printing system.

Abstract: Example updating a supported-supplies database of an image forming apparatus are disclosed. An example method includes receiving an imaging supply in a printer; accessing an action identifier on the imaging supply; and in response to the action identifier, at least one of updating a database of the printer to include a first supported imaging supply previously not supported by or compatible with the printer, or removing a second supported imaging supply previously supported by or compatible with the printer from the database.

Abstract: Example continuous ink supply apparatus, systems and methods are disclosed. An example apparatus includes a housing; a printhead; and a regulator including a lever, a spring coupling the lever to the housing, a bladder, and a valve, a position of the lever relative to the housing being controlled by the bladder, the bladder being inflatable to urge the lever away from a surface of the housing and a plug of the valve to move away from a valve seat to enable fluid to flow through the aperture and into the housing, the regulator to enable a pressure within the housing to be maintained below a threshold pressure to substantially prevent fluid from inadvertently dispensing from the printhead.
