Abstract
Systems and methods for validating electronic signatures contained in a printable document prior to allowing the document to be printed. The systems and methods may be incorporated into a printing device or a computer. Documents without electronic signatures are printed normally. If the document contains one or more electronic signatures, then the electronic signature(s) must be validated before the document is allowed to print. Validation is accomplished by comparing a public key contained in the electronic signature to a public key stored in an electronic signature database. If the electronic signature is validated, then the document may print.
