A calibration site is located along the print line of a thermal ribbon printer, preferably at one end, and includes a thermal sensor for detecting ribbon temperature. During calibration operation, a drive pulse having a preselected waveform is applied to the printhead and special logic adjusts the reference level for the normal drive waveform based on the resulting ribbon temperature.
