Abstract
An automatic print speed control for a barcode printer is shown, the printer includes a printhead to which power is applied during a strobe time to cause the printhead to print. The printer also includes a stepper motor that is responsive to a periodic drive signal for advancing a web of labels or the like past the printhead for printing thereon. The control is responsive to a number of measured operating variables of the barcode printer to adjust the printhead strobe time. The adjusted strobe time is compared to the period of the stepper motor drive signal in order to adjust the speed of the stepper motor if necessary.
