摘要

An array (200) of light emitting semiconductor components for use in a digital printer, each component comprising a driver (220) and at least one light emitting device (210), the array (200) comprising data buses (D 0 , D 1 , D 2 , D 3 ) connecting to first subsets of components, forming a first partition of said components; said array (200) further comprising auxiliary buses (A 0 , A 1 , A 2 , A 3 ) connecting to second subsets of components, forming a second partition of said components; wherein said first partition and said second partition are chosen such that each component can be uniquely identified by the subset of the first and second partition to which it belongs; wherein the data buses (D 0 , D 1 , D 2 , D 3 ) are configured to supply instructions to the first subsets of components; and wherein each component is configured to extract instructions on the basis of its membership of a particular subset according to said second partition.
