Abstract
A printing device consumable item assembly includes a housing containing a consumable item that any compatible printing device uses to print, and a single-use authentication code on the housing. The single-use authentication code authorizes reloading or replacement of any consumable item of a same type as the consumable item within any compatible printing device.
Claims10
A printing device consumable item assembly comprising:
- a housing containing a consumable item that any compatible printing device uses to print;
- a single-use authentication code on the housing, the single-use authentication code authorizing reloading or replacement of any consumable item of a same type as the consumable item within any compatible printing device;
- an access port by which the consumable item is accessible within the housing;
- and
- a cap covering the access port and concealing the single-use authentication code, the cap irreversibly removable to reveal the single-use authentication code in that the cap is permanently altered upon removal, preventing reattachment of the cap to the access port in a manner that is not visually discernible.

A method comprising:
- receiving, by a computing device from a user device or directly from a printing device associated with the user device, a single-use authentication code on a printing device consumable item assembly containing a consumable item, the single-use authentication code authorizing reloading or replacement of any consumable item of a same type as the consumable item within any compatible printing device;
- authenticating, by the computing device, the single-use authentication code;
- upon successful authentication of the single-use authentication code, authorizing, by the computing device, reloading or replacement of any consumable item of the same type within the printing device;
- and
- redeeming, by the computing device, the single-use authentication code to authorize reloading or replacement of any consumable item of the same type within the printing device, without the single-use authentication code having to be loaded onto any account with which both the user device and the printing device are associated.
2 more elements
A printing device comprising:
- print hardware to print using an installed consumable item;
- a processor;
- and
- a memory storing program code executable by the processor to:
- responsive to the installed consumable item having to be replaced or reloaded or having been replaced or reloaded, verify that reloading or replacement of the installed consumable item has been authorized;
- responsive to successful verification that reloading or replacement of the installed consumable item has been authorized, permit printing with the installed consumable item as has been reloaded or replaced or after the installed consumable item has been reloaded or replaced, or permit reloading or replacement of the installed consumable item;
- and
- responsive to unsuccessful verification that reloading or replacement of the installed consumable item has been authorized, prohibit printing with the installed consumable item as has been reloaded or replaced or after the installed consumable item has been reloaded or replaced, or prohibit reloading or replacement of the installed consumable item,
- wherein reloading or replacement of the installed consumable item is authorized via successful authentication of a single-use authentication code on a printing device consumable item assembly containing a consumable item, the single-use authentication code authorizing reloading or replacement of any consumable item of a same type as the consumable item within any compatible printing device.
