The hand-held printer may include an inkjet cap sized to cooperatively engage the inkjet array, wherein the inkjet cap is movable between and open position and a closed position, and a plurality of wipers carried by the inkjet cap, wherein each of the plurality of wipers is configured to engage one of the plurality of inkjets as the inkjet cap moves from the open position to the closed position; and wherein each of the plurality of wipers includes a gasket configured to form a seal adjacent to one of the plurality of inkjets. ## Claims ### Claim 1 A printing device comprising: a cap sized to cooperatively engage a printing element, wherein the cap is movable from an open position to a closed position; a plurality of cleaning elements, wherein the plurality of cleaning elements are carried by the cap; a plurality of gaskets carried by the cap, at least one gasket of the plurality of gaskets abutting at least one cleaning element of the plurality of cleaning elements; wherein the at least one cleaning element of the plurality of cleaning elements is configured to engage the printing element as the cap moves from the open position to the closed position; and wherein the at least one gasket of the plurality of gaskets is configured to form a seal adjacent to the printing element. ### Claim 2 (depends on 1) The printing device of claim 1, further comprising: a lock mechanism configured to releasably engage the cap and maintain the cap in the closed position. ### Claim 3 (depends on 2) The printing device of claim 2, wherein the lock mechanism is spring-loaded. ### Claim 4 (depends on 1) The printing device of claim 1, wherein the at least one gasket of the plurality of gaskets and the at least one cleaning element of the plurality of cleaning elements are a unitary part. ### Claim 5 (depends on 1) The printing device of claim 1, wherein each cleaning element of the plurality of cleaning elements is configured to remove printing substance accumulated near the printing element. ### Claim 6 (depends on 0) The printing device of claim 0, further comprising: a cam slideably coupled to the cap, wherein the cam is configured to guide the cap and the plurality of cleaning elements through a wipe phase and a seal phase as the cap moves from the open position to the closed position. ### Claim 7 (depends on 1) The printing device of claim 1, wherein each of the plurality of cleaning elements includes a leading edge and a trailing edge. ### Claim 8 (depends on 7) The printing device of claim 7, wherein the leading edge defines a curvilinear surface. ### Claim 9 (depends on 7) The printing device of claim 7, wherein the trailing edge defines a sharp edge. ### Claim 10 (depends on 7) The printing device of claim 7, wherein the plurality of cleaning elements are molded from a deformable rubber material. ### Claim 11 A printing device comprising: a cap sized to cooperatively engage a printing element, wherein the cap is movable from an open position to a closed position; a plurality of cleaning elements, wherein the plurality of cleaning elements are carried by the cap and at least one cleaning element of the plurality of cleaning elements is configured to engage the printing element as the cap moves from the open position to the closed position; and a plurality of gaskets carried by the cap, at least one gasket of the plurality of gaskets abutting the at least one cleaning element of the plurality of cleaning elements, wherein each gasket of the plurality of gaskets is configured to form a seal adjacent to the printing element; wherein the printing device is configured to: transition the cap from the open position to the closed position; slide the at least one cleaning element adjacent to the printing element; seal the at least one gasket around the printing element; and create a vacuum by the cooperative deformation of the at least one cleaning element and the at least one gasket against the printing element. ### Claim 12 (depends on 11) The printing device of claim 11, wherein the printing device is further configured to: disengage the at least one cleaning element from the printing element; and disengage the at least one gasket from the printing element. ### Claim 13 (depends on 12) The printing device of claim 12, wherein the printing device is further configured to: transition the cap from the closed position to the open position; and slide at least the one cleaning element adjacent to the printing element as the cap moves from the closed position to the open position. ### Claim 14 (depends on 11) The printing device of claim 11, further comprising: a cam slideably coupled to the cap, wherein the cam is configured to guide the cap and the plurality of cleaning elements through a wipe phase and a seal phase as the cap moves from the open position to the closed position. ### Claim 15 (depends on 11) The printing device of claim 11, further comprising: a lock mechanism configured to releasably engage the cap and maintain the cap in the closed position. ### Claim 16 (depends on 11) The printing device of claim 11, wherein the plurality of cleaning elements are molded from a deformable rubber material. ### Claim 17 A printing method comprising: using at least one gasket from a plurality of gaskets that abut at least one cleaning element from a plurality of cleaning elements; transitioning a cap from an open position to a closed position, wherein transitioning the cap from the open position to the closed position comprises: sliding at least one cleaning element adjacent to the printing element as the cap transitions from the open position to the closed position; sealing the at least one gasket around the printing element as the cap transitions from the open position to the closed position; and creating a vacuum by the cooperative deformation of the at least one cleaning element and the at least one gasket against the printing element as the cap transitions from the open position to the closed position. ### Claim 18 (depends on 17) The method of claim 17, wherein the cap is sized to cooperatively engage the printing element. ### Claim 19 (depends on 17) The method of claim 17, further comprising: disengaging the at least one cleaning element from the printing element; and disengaging the at least one gasket from the printing element. ### Claim 20 (depends on 17) The method of claim 17, wherein creating the vacuum comprises: compressing the at least one cleaning element and the at least one gasket against the printing element; and decreasing the compression of the at least one cleaning element and the at least one gasket against the printing element.
