An apparatus is disclosed comprising first and second pallet supports to engage pallets in at least a first and a second pallet location. The first pallet location positions a pallet to receive output from a print press. The second pallet location is a pre-use pallet holding location. The apparatus further comprises an actuator to move the first and second pallet supports to transfer a first pallet away from the first pallet location and a second pallet from the second pallet holding location to the first pallet location. A method of transferring pallets is also disclosed.

An example stacking system comprises a stacking member movable between a first position in which the stacking member is configured to partially support a first stack of printed substrates, and a second position in which the stacking member is disengaged from the first stack. A receptacle positioned below the stacking member is configured to hold a second stack of printed substrates. A controller is configured to cause the stacking member to move between the first position and the second position when the first stack satisfies a criterion, thereby depositing the first stack into the receptacle on top of the second stack.

An apparatus for reducing vapor emissions from a printer may include a treatment chamber having an inlet and an outlet. While the printer is operating, vapor-laden air may enter the treatment chamber via the inlet and treated air may exit the treatment chamber via the outlet. While the printer is idle, the inlet and outlet can be sealed to prevent vapors located in the treatment chamber from being emitted to the atmosphere.
