Abstract

An approach is provided for securely printing policy-enabled electronic documents. According to the approach, a determination is made at a client device whether policy-enabled printing has been specified for a particular electronic document. If policy-enabled printing has been specified for the particular electronic document, then a determination is made whether a print driver, installed on the client device for supporting printing for a particular printing device, is configured to support policy-enabled printing. Also, a determination is made whether the particular printing device is currently configured to support policy-enabled printing. The particular electronic document is allowed to be processed at the client device for printing only if both the print driver is configured to support policy-enabled printing and the particular printing device is currently configured to support policy-enabled printing.
