DRIVE CONTROL SYSTEM FOR IMPRINTING APPARATUS ABSTRACT The drive control system is employed in a mailing machine and includes a microcomputer in control of a first stepper motor which is a driving communication with the mailing machine transport system. Also under the control of the microcomputer is a second motor in driving communication with the mailing machine print drum assembly and a third motor in driving communication with the mailing machine shutter bar assembly. A speed sensing means is in informing communication with the microcomputer for sensing the incoming velocity of the envelope and a trigger sensing means is in information communication with the microcomputer for sensing the relative position of the envelope with respect to the transport system and printing station. The microcomputer is programmed to determine the peak drum speed (PDS) relative to the speed (IN-SPEED) of the envelope predicated upon information supplied by the speed sensing means and a preselected pitch distance between successive envelopes where the peak drum speed represents the minimum required peak drum speed, and cause the transport system to obtain a initial speed equal to or greater than the IN-SPEED prior the transport system assuming control over the envelope. The microcomputer causes the transport system to speed adjust to a speed equivalent to the peak drum speed and, subsequent to indicia printing by the postage meter print drum, causes the transport system to speed adjust to the previously determined IN-SPEED,
