Media stacking mechanisms

A system, comprising:

• a printing device to generate markings on print media of a first size and a second size that is different than the first size;
• a finisher device coupled to the printing device to:
• receive a first set of print media of the first size;
• receive a second set of print media of the second size;
• and
• receive a third set of print media of the first size;
• a tamper coupled to the finisher device to:
• tamp the first set of print media a first distance based on the first size;
• tamp the second set of print media a second distance based on the second size;
• and
• tamp the third set of print media the first distance based on the first size;
• and
• an ejector coupled to the finisher device to:
• eject the first set of media with a first offset based on the first size;
• eject the second set of media with a second offset to align an edge of the first set of media with an edge of the second set of media;
• and
• eject the third set of media with the first offset to align the edge of the second set of media with an edge of the third set of media, wherein the first set of media, the second set of media, and the third set of media are received as a stack of print media by the finisher device as a single print job such that the finisher device performs a finishing process on the edge of the stack of print media.

A method, comprising:

• determining a size of a plurality of print media sheets of a print job that includes print media of a first size and a second size;
• collecting the plurality of print media sheets at a stacking mechanism that includes a first tamper and a second tamper;
• tamping the plurality of print media sheets with the first tamper that includes a cantilevered surface that adjusts to the first size and the second size of the plurality of print media sheets against the second tamper, wherein the plurality of print media sheets are tamped to generate a stack with a first edge of the stack that is aligned and an opposite edge of the stack that is not aligned;
• performing a finishing process on the first edge of the stack;
• and
• ejecting the plurality of print media sheets to an output tray when the plurality of print media sheets are aligned on the first edge.
