Abstract

Systems, apparatus and methods are described for providing information access to network devices. A directory server registers identification information about a first network device coupled to a first network. The first network and the directory server may be coupled to a second network, which may include a wide area network, public network, or the Internet. The identification information may include a network address of the first network device on the first network, or a network address of the first network on the second network. The directory server may receive and process requests for identification information about registered network devices, and may selectively reply to the requests based on status information of the first network device.

Claims

1. A system for controlling access to a printing environment comprising:

a directory server coupled to a first network via a first router, the directory server comprising;

a memory; and

a message processor configured to register identification information in a directory table in the memory;

at least one client device coupled to a second network; and

at least one printing device coupled to the first network via an additional router, wherein said additional router enforces at least one firewall, wherein the first network is configured inside the firewall, wherein the directory server is configured outside the firewall, wherein said at least one printing device is configured to print at least one file from said at least one client device only after receiving necessary configuration information, and wherein said first network and said second network operate using non-homogeneous communication protocol;

wherein the directory server message processor is configured for registering identification information that at least partially comprises availability information and configuration information;

wherein said at least one client device is configured to send a discrete request to the directory server, said discrete request comprising an availability inquiry about the printing-availability of said at least one printing device; and

wherein the directory server message processor is configured for processing the discrete request and issuing a discrete reply message to the at least one client device, wherein the discrete reply message comprises configuration information for the at least one client device to configure the at least one printer to print files from the at least one client device.

2. The system of claim 1, wherein the at least one printing device is selected from among an inkjet printer, a laser printer, a wide format printer, and a dot matrix printer.

3. The system of claim 1, wherein the at least one client device comprises one of a computer, personal digital assistant, pager, cellular telephone, mobile device, handheld messaging device, facsimile machine, copier, printer, telephone, security camera, household appliance, vending machine, kiosk, digital camera, and Internet protocol telephone.

4. The system of claim 1, wherein the first network comprises a local area network.

5. The system of claim 1, wherein the first network comprises a plurality of interconnected networks.

6. The system of claim 1, wherein the identifying information comprises an address of the first network on the second network.

7. A method for controlling access to a printing environment comprising:

a directory server coupled to a first network via a first router, the directory server comprising;

a memory; and

a message processor configured to register identification information in a directory table in the memory;

at least one client device coupled to a second network; and

at least one printing device coupled to the first network via an additional router, wherein said additional router enforces at least one firewall, wherein the first network is configured inside the firewall, wherein the directory server is configured outside the firewall, wherein said at least one printing device is configured to print at least one file from said at least one client device only after receiving necessary configuration information, and wherein said first network and said second network operate using non-homogeneous communication protocol;

wherein the directory server message processor is configured for registering identification information that at least partially comprises availability information and configuration information;

wherein said at least one client device is configured to send a discrete request to the directory server, said discrete request comprising an availability inquiry about the printing-availability of said at least one printing device; and

wherein the directory server message processor is configured for processing the discrete request and issuing a discrete reply message to the at least one client device, wherein the discrete reply message comprises configuration information for the at least one client device to configure the at least one printer to print files from the at least one client device.

8. The method of claim 7, wherein the at least one printing device is selected from among an inkjet printer, a laser printer, a wide format printer, and a dot matrix printer.

9. The method of claim 7, wherein the at least one client device comprises one of a computer, personal digital assistant, pager, cellular telephone, mobile device, handheld messaging device, facsimile machine, copier, printer, telephone, security camera, household appliance, vending machine, kiosk, digital camera, and Internet protocol telephone.

10. The method of claim 7, wherein the first network comprises a local area network.

11. The method of claim 7, wherein the first network comprises a plurality of interconnected networks.

12. The method of claim 7, wherein the identifying information comprises an address of the first network on the second network.
