摘要： A printer is provided which has a special Emulation Manager function as well as a “code sniffer” function, in which print data received is sent to a code sniffer buffer. A code sniffer function automatically determines the type of emulator that should be called to perform the interpretation or rendering of this print job, and if the code sniffer determines that the correct emulator is PostScript, then the code sniffer scans the data for any “special tokens.” If a special token is found, the PostScript emulator determines if the special token string data is part of a PostScript comment. If it is in the correct format, then the PostScript emulator sets the “mode flag” to the “MacBinary” state, and the code sniffer ceases any further filtering of control characters and disables any change of emulator command that may be received during this print job. The rest of the print job is then interpreted as RAW binary data by the PostScript emulator, until a “UEL” string is encountered.

摘要： An interface is provided between two or more self-describing devices, each having a data store, or two ongoing processes on the same device sharing a common data store. The interface includes a datastream having at least one metavariable that is indicative of at least two or more parameters associated with a device. The datastream occurs between the data store of one transmitting device to the data store or one or more receiving devices or between two or more processes that may or may not share a common data store. The metavariable references or implies a number of other variables and allows devices to effectively communication without knowledge of the underlying variables. The metavariable can be data indicative of the configuration and settings of a device or can be a command altering two or more setting of a device upon receipt of the metavariable by the device. The metavariable also allows the abstraction of commands encompassing two or more variables such that function and conceptual settings can be communicated in one metavariable.

摘要翻译： 在两个或多个自描述设备之间提供接口，每个设备具有数据存储器，或者在共享公共数据存储器的同一设备上的两个正在进行的过程。 接口包括具有至少一个元变量的数据流，其指示与设备相关联的至少两个或多个参数。 数据流发生在一个发送设备的数据存储器到数据存储器或一个或多个接收设备之间，或者在两个或更多个可能共享公共数据存储器或可能不共享数据存储器的进程之间。 变量引用或意味着许多其他变量，并允许设备有效地通信，而不了解基础变量。 元变量可以是指示设备的配置和设置的数据，或者可以是在设备接收到可变元素时改变设备的两个或多个设置的命令。 元变量还允许包含两个或多个变量的命令的抽象，使得功能和概念设置可以在一个变量中传达。
