    • 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.
    • 本发明涉及通过通信网络转发打印作业的方法和装置。 特别地,本发明使得用户能够在可能未指定的位置获得打印作业,并且可能远离打印作业的源。 提供了能够通过网络转发一个或多个打印作业的打印驱动程序。 打印驱动程序可以与任何合适的打印作业源(例如,能够生成可打印文档的计算机的客户端设备)接口以获得打印作业。 打印作业通过网络从打印驱动程序转发到假脱机服务器。 可以在远离客户端设备的位置使用的打印机轮询设备能够经由网络轮询假脱机服务器,以识别与打印机轮询设备相关联的任何打印作业是否可用于当前与之相关联的打印机的打印 打印机轮询设备。 假脱机服务器无需通过防火墙启动与打印机的联系,因为它由打印机轮询设备轮询。 因此,维护网络安全。
