Abstract
Abstract The invention features a high speed thermal printing mechanism having a dichotomized printing sequence. The thermal printing mechanism is particularly useful for printing postal values and indicia upon postage tape in a variable and fixed format, respectively. The variable information can be imprinted by a thermal head under the influence of a microprocessor. The fixed information can be imprinted by an etched thermal print screen.
