Abstract

A printing cartridge includes a cover that defines a cylindrical storage volume and a print media feed slot. A cylindrical hollow core extends along a central axis of the cover. At least one ink container is positioned in the core. A length of print media is rolled about the core and positioned to be fed from the slot. A feed mechanism is positioned in the cover and is engageable by a drive mechanism of a printer from a position outside the cover and operable on the print media to feed the print media from the slot.

Claims

1. A printing cartridge that comprises

a cover that defines a cylindrical storage volume and a print media feed slot;

a cylindrical hollow core that extends along a central axis of the cover, at least one ink container being positioned in the core;

a length of print media rolled about the core and positioned to be fed from the slot; and

a feed mechanism positioned in the cover and engageable by a drive mechanism of a printer from a position outside the cover and operable on the print media to feed the print media from the slot.

2. A printing cartridge as claimed in claim 1, in which the cover includes a pair of cover pieces that engage each other to define the cylindrical storage volume.

3. A printing cartridge as claimed in claim 1, in which a number of ink containers containing respective inks are positioned in the hollow core, each ink container including internal sponge portions.

4. A printing cartridge as claimed in claim 3, in which a sealing cap engages one end of the core, the sealing cap being configured to be pierced by ink feed conduits of the printer aligned with respective ink containers.

5. A printing cartridge as claimed in claim 3, in which one end of the core defines air passages in fluid communication with the ink containers to allow the ingress of air into the respective ink containers while ink is fed from the ink containers.

6. A printing cartridge as claimed in claim 1, in which an authentication integrated circuit is mounted in the cover to be read by a processor of the printer when the printing cartridge is inserted into the printer.

7. A printing cartridge as claimed in claim 1, in which the feed mechanism includes a set of rollers that include a drive roller with a geared end that extends from the cover to engage the drive mechanism of the printer.
