A policy-based printing system is implemented to allow access to a private domain to print using a public domain. The private domain includes private servers that store documents. The public domain includes servers and a printing device. A public policy server uses a domain list and a protocol connection with a private authentication server to validate a user and identify which private domain to access. The public policy server retrieves a policy from a private policy server that configures the parameters for printing using the public domain. The print job data is provided to a public file server until the public policy server confirms that the print job can be sent to the printing device.
