Abstract: A printing-fluid container includes a reservoir having a leading surface with an outer perimeter. Redundant interface elements are recessed from the leading surface interior the outer perimeter.

Abstract: A printing-fluid container includes a printing-fluid reservoir configured to hold printing fluid. A printing-fluid interface is configured to output printing fluid from the printing-fluid reservoir and an air-interface is configured to regulate an operating pressure within the printing-fluid reservoir.

Abstract: A printing-fluid container includes a reservoir. An electrical interface is coincident with a first axis and includes a first leading surface or contact pad. A fluidic interface is coincident with a second axis and perpendicular to the first axis. The fluidic interface includes a second leading surface or entry point. The first void is recessed from the first leading surface or contact pad and the second leading surface or first entry point. The first void is coincident with the first axis. A second void is recessed from the first leading surface or contact pad and the second leading surface or second entry point. The second void is coincident with both the first axis and the second axis.

Abstract: A printing-fluid container includes a reservoir having an outer-face. A keying pocket is recessed from the outer-face of the reservoir and configured to mate with a complementary key post of a printing-fluid container bay.

Abstract: A method of filling a printing fluid container including providing a printing-fluid container that includes a leading surface having an outer-perimeter with a top edge and a bottom edge, wherein the printing-fluid container includes a printing-fluid interface positioned on the leading surface proximate the bottom edge and an air-interface positioned on the leading surface proximate the top edge in generally vertical alignment with the printing-fluid interface. The method further includes passing printing fluid through the printing-fluid interface into the printing-fluid container, and permitting air to pass through the air-interface out of the printing-fluid container.

Abstract: A printing-fluid container designed for lateral insertion into a printing-fluid container bay includes a leading surface. The printing-fluid container also includes an alignment pocket recessed into a center portion of the leading surface. The alignment pocket is configured to mate with an outwardly-extending alignment member of the printing-fluid container bay so as to guide the printing-fluid container into a desired position with a desired orientation.

Abstract: A printing-fluid container includes a reservoir configured to hold printing fluid. The reservoir includes a substantially planar front surface and a bottom surface defining a well in a low portion of the reservoir. A cross-sectional area of the reservoir in the well is less than a cross-sectional area of the reservoir above the well. The printing-fluid container also includes a fluid interface on the front surface adjacent the well, which is configured to releasably receive a fluid connector to laterally draw printing fluid from the well.

Abstract: A printing-fluid container includes a leading portion having a substantially planar profile, and a trailing portion adapted to cooperate with the leading portion to define a bounded volume having an ink capacity. The leading portion is configured to mate with a complementarily configured ink-container bay.
