    • In client-server architectures, systems and methods for XPS based printer redirection are disclosed. In an implementation, a client computing device issues a print command to print an application hosted on a server computing device. The server computing device implements a generic printer driver to emulate exact properties of a client printer driver installed in the client computing device. The generic printer driver redirects one or more calls related to printer settings to the client printer driver. The client computing device returns the printer settings which are combined with the application (to be printed) to generate an XPS file. The XPS file is redirected to a printer connected to the client computing device for printing.
    • 在客户端 - 服务器体系结构中,公开了基于XPS的打印机重定向的系统和方法。 在实现中,客户端计算设备发出打印命令以打印托管在服务器计算设备上的应用。 服务器计算设备实现通用打印机驱动程序来模拟安装在客户端计算设备中的客户端打印机驱动程序的确切属性。 通用打印机驱动程序将与打印机设置相关的一个或多个调用重定向到客户端打印机驱动程序。 客户端计算设备返回与应用程序(待打印)组合的打印机设置,以生成XPS文件。 XPS文件被重定向到连接到客户端计算设备的打印机的打印机。

    • The present invention extends to methods, systems, and computer program products for controlling the transfer of terminal server data. In some embodiments, contending request to send terminal server data are resolved by a flow control module situated between a terminal server protocol and a transport/network protocol. The flow control module utilizes channel priorities along with amounts of previously sent data per channel to determine how to distribute bandwidth in a relatively controlled manner between contending channels. The flow control module can be configured to intercept communication between terminal server protocol and a transport/network protocol to facilitate bandwidth distribution. In other embodiments, data is simultaneously sent over multiple channels of terminal server connection. A first write operation obtains a lock on a corresponding channel but the channel lock does not prevent write operations on other channels.
    • 本发明涉及用于控制终端服务器数据传输的方法,系统和计算机程序产品。 在一些实施例中,发送终端服务器数据的竞争请求由位于终端服务器协议和传输/网络协议之间的流控制模块解决。 流量控制模块利用信道优先级以及每个信道先前发送的数据量来确定如何在竞争信道之间以相对受控的方式分配带宽。 流控制模块可以被配置为拦截终端服务器协议和传输/网络协议之间的通信,以便于带宽分配。 在其他实施例中,数据同时通过多个通道的终端服务器连接发送。 第一次写入操作获得相应通道上的锁定,但是通道锁定不会阻止对其他通道的写入操作。
