Abstract
A printer comprising a printhead configured to selectively cause a mark to be created on a substrate provided adjacent to the printer, the printhead having a first configuration in which the printhead is spaced apart from the printing surface and a second configuration in which the printhead is configured to press the substrate against a printing surface during a printing operation. The printer further comprises a printhead drive assembly configured to cause movement of the printhead towards and away from the printing surface between the first and second configurations, the printhead drive assembly comprising a permanent magnet and an electromagnet. When the electromagnet is in a first condition, an attractive magnetic force is generated between the permanent magnet and the electromagnet, and when the electromagnet is in a second condition, a repulsive magnetic force is generated between the permanent magnet and the electromagnet, each of said attractive and repulsive magnetic forces being configured to one of urge the printhead away from and towards the printing surface. The printhead drive assembly is configured such that, when the printhead is in each of the first and second configurations, it is retained in that configuration by the printhead drive assembly when the electromagnet is in the first condition, the printhead being retained in one of the first and second configurations by said attractive magnetic force generated between the permanent magnet and the electromagnet.
