    • Methods and structure for verifying information in a device capabilities (DevCaps) file associated with a printing system. A job ticket generator generates test job tickets based on the DevCaps file and transmits the generated tickets to a job ticket validator. The validator validates that each received ticket can be correctly executed by the printing system. The generator accesses the DevCaps file to determine features configured on the printing system and possible values for each of the specified features. The validator returns a success or failure signal and the results of each test job ticket may be logged. An error status indicates an error in the DevCaps file relative to the present configuration of the printing system. The validator may be operable within the printing system such as a PostScript program executed by the printer controller or may be operable in a computer system coupled with the generator.
    • 用于验证与打印系统相关联的设备能力(DevCaps)文件中的信息的方法和结构。 作业单生成器根据DevCaps文件生成测试作业单,并将生成的票据发送到作业单验证器。 验证器验证每个接收到的票证可以由打印系统正确执行。 生成器访问DevCaps文件以确定在打印系统上配置的功能以及每个指定功能的可能值。 验证器返回成功或失败信号,并且可能会记录每个测试作业单的结果。 错误状态指示相对于打印系统当前配置的DevCaps文件中的错误。 验证器可以在打印系统内操作,例如由打印机控制器执行的PostScript程序,或者可以在与发生器耦合的计算机系统中操作。

    • This disclosure concerns methods for fabrication of integrated high speed optoelectronic devices. In one example of such a method, a device region that includes a top surface and a bottom surface is formed on a top surface of a substrate. The device region may take the form of an optical emitter, such as a VCSEL, or a detector, such as a photodiode. Next, an isolation region is formed that is configured such that the device region is surrounded by the isolation region. A superstrate is then disposed on the top surface of the device region. Finally, a micro-optical device, such as a lens, is placed on a top surface of the superstrate.
