Abstract: A height adjustment apparatus for a print carriage comprises a support for supporting the print carriage and a moving mechanism. The support has an upper support surface configured to slidingly engage a surface of the print carriage. The height of the support surface in a first direction increases in a second direction, perpendicular to the first direction. The moving mechanism is configured to move the support in the second direction, wherein when the support is moved in the second direction, the print carriage surface is configured to slide relative to the support surface to move the print carriage in the first direction.

Abstract: An example apparatus is for printing to a substrate. The example apparatus comprises a printing fluid device and an air flow device. The printing fluid device is for transferring printing fluid to a substrate. The air flow device is to create an air curtain so that any printing fluid residue from the transfer of the printing fluid to the substrate is at least partially prevented from migrating toward a user of the apparatus.
