摘要： The present disclosure provides a printer apparatus including a thermoelectric cooling assembly and a processor coupled to the thermoelectric cooling assembly. The thermoelectric cooling assembly includes a thermoelectric cooling element that includes a first substrate, a second substrate, and a first plurality of semiconductor elements electrically coupled to a second plurality of semiconductor elements in a space between the first substrate and the second substrate. The thermoelectric cooling element includes a base plate electrically coupled to the first substrate. The base plate is positioned proximate to a plurality of labels traversing above the thermoelectric cooling assembly. The processor receives sensor signals indicative of a temperature of a label that comes in contact with the thermoelectric cooling assembly, compares the temperature of the label with a threshold temperature, and generates an output signal indicative of current supplied to the thermoelectric cooling element to adjust the temperature of the thermoelectric cooling element.

摘要： Various embodiments disclose a method for operating a printer apparatus that includes a print head. The method includes causing a media hub to retract a media in a retract direction along a media path. Further, the method includes causing a first media sensor to generate a first signal during retraction of the media. Furthermore, the method includes monitoring the first signal to detect at least one of a leading edge or a trailing edge of a label of the plurality of labels. Upon detecting the at least one of the leading edge or the trailing edge of the label, causing the media hub to retract the media by at least a predetermined distance, wherein the predetermined distance is a distance between the print head and the first media sensor.
