Abstract

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.

First claim

What is claimed is:

1. A method for printing a document from a private domain to a printing device, the method comprising:
establishing a connection using a verification token from a private authentication server to a public policy server;
providing a domain list to the public policy server;
generating an authentication token at the private authentication server for a domain from the domain list;
retrieving a policy of the domain upon receipt of the authentication token and the domain at a private policy server;
generating a job token based on the policy at the public policy server; and
sending a print job associated with the job token from a private job server to a printing device using the public policy server.

2. The method of claim 1 , further comprising validating the user at the private authentication server to generate the authentication token.

3. The method of claim 1 , wherein the connection is a protocol connection that is established as long as the verification token is stored on the public policy server.

4. The method of claim 3 , further comprising generating the verification token at the private authentication server.

5. The method of claim 1 , further comprising selecting the print job from a job list retrieved according to the job token.

6. The method of claim 5 , further comprising retrieving job data for the print job after the selection.

7. The method of claim 1 , further comprising using a confirmation token to determine whether to send the print job to the printing device.

8. A printing system configured to:
establish a connection using a verification token from a private authentication server to a public policy server;
provide a domain list to the public policy server;
generate an authentication token at the private authentication server for a domain from the domain list;
retrieve a policy of the domain upon receipt of the authentication token and the domain at a private policy server;
generate a job token based on the policy at the public policy server; and
send a print job associated with the job token from a private job server to a printing device using the public policy server.

9. The printing system of claim 8 , further configured to validate the user at the private authentication server to generate the authentication token.

10. The printing system of claim 8 , wherein the connection is a protocol connection that is established as long as the verification token is stored on the public policy server.

11. The printing system of claim 10 , further configured to generate the verification token at the private authentication server.

12. The printing system of claim 8 , further configured to select the print job from a job list retrieved according to the job token.

13. The printing system of claim 12 , further configured to retrieve job data for the print job after the selection.

14. The printing system of claim 8 , further configured to use a confirmation token to determine whether to send the print job to the printing device.
