ABSTRACT:
A microprocessor controller thermal printer particularly usable in a hand-held labeler for printing labels on a composite web detects indices on the web and automatically adjusts the distance that the web is advanced based on a measurement of the distance between indices made during a paper loading sequence. The printer includes automatic jam detection that measures the length of time that one of the indices is being detected and provides a jam indication if it is detected for more than a predetermined time period. A solenoid operated braking mechanism retains the web in position upon completion of a printing cycle to prevent the web from being moved relative to the print head while the label is being applied.
