Abstract
In accordance with the invention a multi-chamber printhead barrier design that is compensated for differences in ink properties is disclosed. The printhead comprises different groups of firing chambers, each group dedicated to a different ink. The barrier design is configured to a particular ink property such as viscosity, in order to provide similar ink refill characteristic for the different groups of firing chambers.
