Abstract
A method of selectively setting the print cycle speed of a thermal printing apparatus such as a thermal postage meter. The thermal postage meter has a thermal print head and an optical reader under the control of a micro controller for printing an image on a sheet like material comprising the steps of first causing said micro processor to be programmed to first cause said thermal print head to print a test pattern just prior to print said image. The optical reader reads said the pattern intensity. The microprocessor is programmed to select a print cycle speed as a function of the test pattern intensity.
