Abstract

A print server system includes an email onramp configured to receive emails via a network. The email onramp is configured to distinguish between received print emails that specify print operations and received update emails that include software updates. The server system includes a print job controller that is configured to orchestrate the printing of documents based on print emails received via the onramp. The server system includes a software update controller configured to automatically update software within the server system based on software updates in update emails received via the onramp.

Claims

1. A print server system, comprising:

an email onramp configured to receive emails via a network, the email onramp configured to distinguish between received print emails that specify print operations and received update emails that include software updates;

a print job controller configured to orchestrate the printing of documents based on print emails received via the onramp; and

a software update controller configured to automatically update software within the server system based on software updates in update emails received via the onramp.

2. The print server system of claim 1, wherein the email onramp is configured to verify that a sender of a received update email is an authorized sender.

3. The print server system of claim 2, wherein the email onramp is configured to discard received update emails from a sender that is not verified as being an authorized sender.

4. The print server system of claim 2, wherein the email onramp is configured to perform an authentication operation to verify that the sender of a received update email is authentic.

5. The print server system of claim 1, wherein the email onramp is configured to receive a forwarded update email that includes a software update, the forwarded update email sent from a first sender to a second sender, and manually forwarded from the second sender to the server system, and wherein the software update controller is configured to automatically update software within the server system based on the forwarded update email.

6. The print server system of claim 5, wherein the email onramp is configured to verify that at least one of the first and the second senders is an authorized sender.

7. The print server system of claim 6, wherein the email onramp is configured to perform an authentication operation to verify that at least one of the first and the second senders is authentic.

8. The print server system of claim 5, wherein the email onramp is configured to verify that both of the first and the second senders are authorized senders.

9. The print server system of claim 8, wherein the email onramp is configured to perform an authentication operation to verify that both of the first and the second senders are authentic.

10. The print server system of claim 1, wherein the software within the server system includes a plurality of substantially independent software components, and wherein the software update controller is configured to dynamically update selected ones of the software components while the print server system is processing a print email.

11. The print server system of claim 10, wherein the software components are Java software components.

12. The print server system of claim 1, wherein the software update controller is configured to identify when the print server system is idle, and automatically update the software within the server system when the print server system is identified as being idle.

13. The print server system of claim 12, wherein the software update controller is configured to identify that the print server system is idle if the print server system is not currently processing any print emails.

14. The print server system of claim 1, wherein the software update controller is configured to test the print server system after updating the software within the server system.

15. The print server system of claim 14, wherein the software update controller is configured to automatically uninstall a software update if the test of the print server system indicates a problem with operation of the print server system.

16. A method for updating software of a plurality of print servers, the method comprising:

maintaining an email list including a plurality of email addresses, each email address in the email list associated with at least one of the print servers;

sending an email message with a software update attached thereto to each of the email addresses in the email list;

receiving the email message at each of the print servers;

verifying at each of the print servers that the received email message is from an authorized source; and

each print server automatically detaching the software update from the email message and automatically updating software of the print server based on the software update if the email message is verified as being from an authorized source.

17. The method of claim 16, wherein the plurality of email addresses includes first and second sets of email addresses, each email address in the first set identifying an address for one of the print servers, each email address in the second set identifying an address for a person.

18. The method of claim 17, wherein the email message received by at least one of the print servers is a forwarded email that has been manually forwarded to the print server by a person with an email address in the second set.

19. The method of claim 16, and further comprising:

each print server verifying that a source of the received email message is authentic.

20. The method of claim 16, and further comprising:

each print server identifying when the print server is idle, and performing the step of automatically updating the software when the print server is identified as being idle.

21. A server system to facilitate email printing, the system comprising:

means for receiving emails;

means for distinguishing between print emails that specify print requests and software update emails that include software updates;

means for orchestrating the printing of documents based on received print emails;

means for verifying that a sender of a software update email is an authorized sender; and

means for automatically installing the software update in the server system if the sender is verified as being an authorized sender.

22. The server system of claim 21, and further comprising:

means for verifying authenticity of a sender of a software update email.

23. The server system of claim 21, wherein the means for receiving emails is configured to receive a forwarded software update email that includes a software update, the forwarded update email sent from a first sender to a second sender, and manually forwarded from the second sender to the server system, and wherein the means for automatically installing the software update is configured to automatically install in the server system the software update from the forwarded software update email.

24. The server system of claim 23, wherein the means for receiving emails further comprises:

means for verifying that at least one of the first and the second senders is an authorized sender, and discarding the forwarded software update email if at least one of the first and the second senders is not an authorized sender.

25. The server system of claim 23, wherein the means for receiving emails further comprises:

means for verifying that both of the first and the second senders are authorized senders, and discarding the forwarded software update email if both of the first and the second senders are not authorized senders.

26. The server system of claim 21, wherein the means for automatically installing the software update further comprises:

means for identifying when the server system is idle; and

wherein the means for automatically installing the software update is configured to wait until the server system is identified as being idle before installing the software update.

27. A computer-readable medium having computer-executable instructions for performing a method of updating software of a print server, the method comprising:

receiving emails with the print server;

determining whether each received email is a print email specifying a print request or a software update email that includes a software update attached thereto;

verifying that each received software update email is from an authorized sender; and

automatically updating software of the print server based on received software update emails.
