Abstract

A method of communicating with a shared imaging apparatus connected to a computer network, wherein communication over the network is facilitated through use of network packets, includes the steps of providing the shared imaging apparatus with networking hardware; providing the shared imaging apparatus with imaging apparatus firmware; defining a data channel associated with the networking hardware; instructing the networking hardware to accept information on the data channel from a user that owns the data channel; processing automatic Internet Protocol (IP) address negotiation network packets with the imaging apparatus firmware when the data channel is not owned; and processing second types of network packets, different from the automatic IP address negotiation network packets, by the networking hardware of the shared imaging apparatus when the data channel is owned.

Claims

1. A method of communicating with a shared imaging apparatus connected to a computer network, wherein communication over said network is facilitated through use of network packets, said method comprising the steps of:

providing said shared imaging apparatus with networking hardware;

providing said shared imaging apparatus with imaging apparatus firmware;

defining a data channel associated with said networking hardware;

instructing said networking hardware to accept information on said data channel from a user that owns said data channel;

processing second types of network packets, different from said automatic IP address negotiation network packets, by said networking hardware of said shared imaging apparatus when said data channel is owned, wherein when said data channel is not owned, then determining whether to place said shared imaging apparatus in an automatic IP address negotiation state, and if said shared imaging apparatus is placed in said automatic IP address negotiation state, then attempting to automatically assign an IP address to said shared imaging apparatus.

2. The method of claim 1, wherein the step of processing automatic IP address negotiation network packets includes at least one of constructing, sending and receiving said automatic IP address negotiation network packets.

3. The method of claim 1, wherein said IP address is assigned automatically using a Dynamic Host Configuration Protocol (DHCP).

4. The method of claim 1, wherein said automatic IP address negotiation network packets includes Dynamic Host Configuration Protocol (DHCP) packets and Address Resolution Protocol (ARP) packets.

5. The method of claim 1, wherein said second types of said network packets comprises a proprietary protocol packet.

6. The method of claim 1, wherein said second types of said network packets comprise imaging data.

7. The method of claim 1, wherein when said data channel is not owned, then determining whether to place said shared imaging apparatus in an automatic Internet Protocol (IP) address negotiation state, and if said shared imaging apparatus is placed in said automatic IP address negotiation state, then attempting to automatically renew a current IP address for said shared imaging apparatus.

8. The method of claim 7, wherein said renewal of said current IP address is accomplished using a Dynamic Host Configuration Protocol (DHCP).

9. The method of claim 1, wherein when said shared imaging apparatus is in an idle state, then determining whether to place said shared imaging apparatus in an automatic Internet Protocol (IP) address negotiation state, and if said shared imaging apparatus is placed in said automatic IP address negotiation state, then attempting to automatically assign an IP address for said shred imaging apparatus.

10. The method of claim 1, wherein when said shared imaging apparatus is in an imaging state said networking hardware accepts said second types of network packets on said data channel only from said user that owns said data channel.

11. The method of claim 1, wherein when said shared imaging apparatus is in an imaging state, said networking hardware disregards all said automatic IP address negotiation network packets and all imaging data packets received from any user that does not own said data channel.

12. A method of communicating with a shared imaging apparatus connected to a computer network, wherein communication over said network is facilitated through use of network packets, said method comprising the steps of:

providing said shared imaging apparatus with networking hardware;

providing said shared imaging apparatus with imaging apparatus firmware;

defining a data channel associated with said networking hardware;

instructing said networking hardware to accept information on said data channel from a user that owns said data channel;

processing automatic Internet Protocol (IP) address negotiation network packets with said imaging apparatus firmware when said data channel is not owned; and

processing second types of network packets, different from said automatic IP address negotiation network packets, by said networking hardware of said shared imaging apparatus when said data channel is owned, wherein when said data channel is not owned, then determining whether to place said shared imaging apparatus in an automatic Internet Protocol (IP) address negotiation state, and if said shared imaging apparatus is placed in said automatic IP address negotiation state, then attempting to automatically renew a current IP address for said shared imaging apparatus.

13. The method of claim 12, wherein the step of processing automatic IP address negotiation network packets includes at least one of constructing, sending and receiving said automatic IP address negotiation network packets.

14. The method of claim 12, wherein when said data channel is not owned, then determining whether to place said shared imaging apparatus in an automatic IP address negotiation state, and if said shared imaging apparatus is placed in said automatic IP address negotiation state, then attempting to automatically assign an IP address to said shared imaging apparatus.

15. The method of claim 14, wherein said IP address is assigned automatically using a Dynamic Host Configuration Protocol (DHCP).

16. The method of claim 12, wherein said automatic IP address negotiation network packets includes Dynamic Host Configuration Protocol (DHCP) packets and Address Resolution Protocol (ARP) packets.

18. The method of claim 12, wherein said second types of said network packets comprise imaging data.

19. The method of claim 12, wherein said renewal of said current IP address is accomplished using a Dynamic Host Configuration Protocol (DHCP).

20. The method of claim 12, wherein when said shared imaging apparatus is in an idle state, then determining whether to place said shared imaging apparatus in an automatic Internet Protocol (IP) address negotiation state, and if said shared imaging apparatus is placed in said automatic IP address negotiation state, then attempting to automatically assign an IP address for said shared imaging apparatus.
