Abstract
A computer implemented method, data processing system, and computer usable program code are provided for detecting a printer condition. A set of signals is received from a sensor in a printer. A current state of a paper roll within the printer is detected within the set of signals. Responsive to the current state indicating that the paper roll moved from a desired position between a set of devices, a response signal is sent to the user of the printer. Alternatively, in response to the current state indicating that the paper roll moved from the desired position, a number of paper line feed commands that are issued are counted. A determination is made as to whether the number of paper line feed commands that are issued exceeds a predetermined value. Responsive to the number of paper line feed commands exceeding the predetermined value, the response signal is sent.
