Print driver apparatus and methods for forwarding a print job over a network
View Patent ↗The present invention relates to methods and apparatus for forwarding a print job over a communications network. In particular, the present invention enables a user to obtain print jobs at a location which may be unspecified, and which may be remote from the source of the print job. A print driver is provided which is capable of forwarding one or more print jobs over a network. The print driver may be interfaced with any suitable print job source (e.g., a client device capable of generating a printable document, such as a computer) to obtain a print job. The print job is forwarded from the print driver, over the network, to a spooling server. A printer polling device, which may be used at a location remote from the client device, is capable of polling a spooling server via the network to identify whether any print jobs associated with the printer polling device are available for printing at a printer currently associated with the printer polling device. The spooling server need not initiate contact with the printer through a firewall, since it is polled by the printer polling device. Thus, network security is maintained.
1. A method for communicating a print job over a network, comprising:
providing a print driver;
operably associating the print driver with a client device, said client device capable of generating a printable document and providing print requests to the print driver; and
enabling said print driver to forward the print job to a spooling server via the network;
wherein:
said spooling server is capable of receiving and storing said print job from the print driver via the network;
a printer for printing said print job is separated from said spooling server by a gateway firewall;
said spooling server is capable of forwarding the print job to the printer in response to a polling request for said print job such that reconfiguration of the gateway firewall is not required.
2. A method for communicating a print job over a network, comprising:
providing a print driver;
operably associating the print driver with a client device, said client device capable of generating a print job and providing print requests to the print driver; and
enabling said print driver to forward the print job to a spooling server via the network;
wherein:
said print driver forwards said print job to said spooling server as web-style traffic; and
said spooling server forwards said print job through a first gateway firewall to a printer as web-style traffic such that reconfiguration of the first gateway firewall is not required.
3. The method of claim 2 , wherein:
the print driver is located within a second gateway firewall;
the spooling server is located outside of said first and second gateway firewalls; and
the print driver forwards the print job to the spooling server such that reconfiguration of the second gateway firewall is not required.
4. A method for communicating a print job over a network, comprising:
providing a print driver;
operably associating the print driver with a client device, said client device capable of generating a print job and providing print requests to the print driver; and
enabling said print driver to forward the print job to a spooling server located via the network;
providing a personal identification number (PIN) with each print job forwarded to the spooling server;
storing one or more print jobs at the spooling server according to the PIN; and
forwarding the print job from the spooling server through a gateway firewall to a printer such that reconfiguration of the gateway firewall is not required.
5. A print driver for communicating a print job over a network, comprising:
an interface for receiving a print job from a client device, said client device capable of generating a print job and providing print requests to the print driver; and
a transmitter enabling said print driver to forward the print job to a spooling server via the network; wherein:
said spooling server is capable of receiving and storing said print job from the print driver via the network;
a printer for printing the print job is separated from said spooling server by a gateway firewall;
said spooling server is capable of forwarding the print job to the printer in response to a polling request for said print job such that reconfiguration of the gateway firewall is not required.
6. A print driver for communicating a print job over a network, comprising:
an interface for receiving a print job from a client device, said client device capable of generating a print job and providing print requests to the print driver; and
a transmitter enabling said print driver to forward the print job to a spooling server via the network; wherein:
said print driver forwards said print job to said spooling server as web-style traffic; and
said spooling server forwards said print job through a first gateway firewall to a printer as web-style traffic such that reconfiguration of the first gateway firewall is not required.
7. The print driver of claim 6 , wherein:
the print driver is located within a second gateway firewall;
the spooling server is located outside of said first and second gateway firewalls; and
the print driver forwards the print job to the spooling server such that reconfiguration of the second gateway firewall is not required.
8. A print driver for communicating a print job over a network, comprising:
an interface for receiving a print job from a client device, said client device capable of generating a print job and providing print requests to the print driver; and
a transmitter enabling said print driver to forward the print job to a spooling server via the network; wherein:
personal identification number (PIN) is provided with each print job forwarded to the spooling server;
the one or more print jobs are stored at the spooling server according to the PIN; and
the print job is forwarded from the spooling server through a gateway firewall to a printer such that reconfiguration of the gateway firewall is not required.
9. The method of claim 1 , wherein said polling request is automatically forwarded to the spooling server from a printer polling device associated with the printer.
10. The print driver of claim 5 , wherein said polling request is automatically forwarded to the spooling server from a printer polling device associated with the printer.
