Abstract
The invention provides a method of controlling the pressure applied to a substrate being printed by a thermal transfer printing head. The head displacement facility includes a resilient member such as a spring which undergoes deflection as the print head engages the substrate. The method comprises monitoring both print head position and spring deflection to control the pressure applied by the print head.
