Methods and systems for cross-process printing
Abstract:
The present invention relates to printing from a restricted process. An embodiment includes receiving a request to print content at a restricted process, providing the request to print content to a privileged process, retrieving configuration information using the privileged process, processing the configuration information using the restricted process, generating one or more drawing commands using the restricted process and providing the drawing commands to the privileged process. Another embodiment includes, receiving a command to print content at a restricted process, providing at least the command to a privileged process, receiving configuration information from the privileged process and generating one or more drawing commands based on the configuration information using the restricted process, generating a serialized buffer of the content based on the configuration information and providing the serialized buffer and the drawing commands to the privileged process. In this way, a restricted process may print data without directly communicating with the printer leading to a more secure computing environment.
