<p>A stamp printing machine has print drum (14) carrying print wheels (64) which are settable by push buttons (15,16) to print a selected value of postage charge. The drum (14) is driven by a mechanical device such as tensator spring motor (54). The motor (54) is manually primed and a trip lever (41) operated by insertion of mail item releases the print drum (14) to rotate through one revolution to print the stamp on the mail item. The stamp machine may include a calculator (23) on which the postage value may be manually entered. Electrical contacts (66) operated by the rotation of the drum (14) are connected across the M+ button of the calculator (23) to add the postage amount to its memory.</p>
