Disclosed are devices, including both a front-end computerized device used to submit a print job and a printing device receiving a print job, that can detect a floating signature on the signature page of an electronic document in the print job and can halt printing of that print job until further action is taken by a user. The devices can apply a set of heuristics to analyze the electronic document in order to determine whether it has a signature page and, if so, whether the signature page contains a floating signature. When a floating signature is detected, the device can notify a user and can preclude printing of the print job until such time as a response to the notification is received. Also disclosed herein are associated methods for detecting a floating signature and for halting printing of a print job until further action is taken.
