ABSTRACT:
An off-carriage printing system with high performance tubing. The printing system includes a media transporting system for transporting a print medium along a medium path to a print area, a scanning carriage for holding a printing structure including a printhead, and a scanning apparatus for scanning the carriage along a scanning axis transverse to the media path at the print area. The system further includes fixed ink supply station including an ink reservoir. A fluid conduit for the flow of ink, interconnects between the ink reservoir of the fixed ink supply station and the printing structure, the fluid conduit including a length of hollow flexible multiple layer tubing routed such that a flexible loop is formed therein. The multiple layer tubing comprises at least one inner barrier layer to water vapor transmission from the ink, at least one barrier layer to oxygen permeability, and at least one outer barrier layer to water vapor transmission from the atmosphere.
