Abstract
A printing system comprising a pen comprising a number of print bars; each print bar comprising a number of printheads in which the printheads are grouped to a number of printheads from each of the number or print bars, the grouped printheads forming a slice and in which the printheads of the slice are electrically coupled to a common power supply unit. A printing pen comprising a number of print bars in which each of the number of print bars comprises a number of printheads, in which the number of printheads are grouped together to form a slice, the slice comprising a printhead from each of the print bars, and in which the slice is powered by a common power supply unit.

A printing system comprising:
- a pen comprising a number of print bars;
- each print bar comprising a number of printheads;
- in which the printheads are grouped with a number of printheads from each of the number of print bars, the grouped printheads forming a slice;
- in which the slice comprises printheads from each print bar that run parallel with each other and parallel with respect to the direction a medium is passed under the pen;
- and
- in which the printheads of the slice are electrically coupled to a common power supply unit.
A printing pen comprising:
- a number of print bars, in which each of the number of print bars comprises a number of printheads;
- in which the number of printheads are grouped together to form a slice, the slice comprising a printhead from each of the print bars;
- in which the slice is to be powered by a common power supply unit;
- and
- wherein the printing pen may be expanded perpendicularly with respect to the direction a medium is passed under the printing pen by adding a new slice comprising a new group of printheads to the printing pen.
A method of manufacturing a pen of a printing system, comprising:
- grouping a number of printheads of a print bar into a number of perpendicularly arranged slices;
- electrically coupling a power supply unit to each slice;
- and
- expanding the pen perpendicularly with respect to the direction a medium is passed under the pen by adding a new slice comprising a new group of printheads to the pen and the new slice comprises a number of new printheads equal to the number of existing print bars.
