Abstract
摘要
This document specifies the requirements and uses cases for some optional administrative operations for use with the Internet Printing Protocol (IPP) version 1.0 and version 1.1. Some of these administrative operations operate on the IPP Job and Printer objects. The remaining operations operate on a new Device object that more closely models a single output device.
本文件规定了与Internet打印协议（IPP）1.0版和1.1版一起使用的一些可选管理操作的要求和用例。其中一些管理操作对IPP作业和打印机对象进行操作。其余的操作操作在一个新的设备对象上进行，该对象对单个输出设备进行了更紧密的建模。

1 Introduction
1导言
The Internet Printing Protocol (IPP) is an application level protocol that can be used for distributed printing using Internet tools and technologies. IPP version 1.1 ([RFC2911, RFC2910]) focuses on end user functionality with a few administrative operations included (for a description of the base IPP documents, see Appendix A). This document defines the requirements and use cases for additional optional end user, operator, and administrator operations used to control Job objects, Printer objects (see [RFC2911]) and a new Device object. The new Device object more closely models a single output device and has no notion of a job, while the Printer object models a print service which understands jobs and may represent one or more output devices.
Internet打印协议（IPP）是一种应用程序级协议，可用于使用Internet工具和技术进行分布式打印。IPP版本1.1（[RFC2911，RFC2910]）侧重于最终用户功能，包括一些管理操作（有关基本IPP文档的说明，请参见附录a）。本文档定义了用于控制作业对象、打印机对象（请参见[RFC2911]）和新设备对象的附加可选最终用户、操作员和管理员操作的要求和用例。新设备对象更接近于对单个输出设备进行建模，并且没有作业的概念，而打印机对象对理解作业并可能表示一个或多个输出设备的打印服务进行建模。
The scope of IPP is characterized in RFC 2567 [RFC2567] "Design Goals for an Internet Printing Protocol". It is not the intent of this document to revise or clarify this scope or conjecture as to the degree of industry adoption or trends related to IPP within printing systems. It is the intent of this document to extend the original set of operations - in a similar fashion to the Set1 extensions which referred to IPP/1.0 and were later incorporated into IPP/1.1.
RFC 2567[RFC2567]“互联网打印协议的设计目标”中描述了IPP的范围。本文件无意修订或澄清本范围或关于印刷系统内IPP的行业采用程度或趋势的推测。本文件旨在以与Set1扩展类似的方式扩展原始操作集，Set1扩展指IPP/1.0，后来被并入IPP/1.1。

3 Requirements and Use Cases
3需求和用例
The Administrative operations for Job and Printer objects will be defined in one document [ipp-ops-set2]. The Administrative operations for Device objects will be defined in a separate document. The requirements are presented here together to show the parallelism.
作业和打印机对象的管理操作将在一个文档[ipp-ops-set2]中定义。设备对象的管理操作将在单独的文档中定义。这些需求在这里一起展示，以显示并行性。
1. Have separate operations for affecting the IPP Printer versus affecting the Output Device, so its clear what the intent of each is, and implementers can implement one or the other or both.
1. 对影响IPP打印机和影响输出设备有单独的操作，因此很清楚每个操作的目的是什么，实施者可以实现其中一个或另一个，或者两者都可以。
2. Support fan-out of Printer objects.
2. 支持扇出打印机对象。
3. Support fan-out of Output Devices.
3. 支持扇出输出设备。
4. Support fan-in of Printer objects, as long as it doesn't make the semantics more complicated when not supporting fan-in.
4. 支持打印机对象的扇入，只要不支持扇入时不会使语义更加复杂。
5. Support fan-in of output objects, as long as it doesn't make the semantics more complicated when not supporting fan-in.
5. 支持输出对象的扇入，只要不支持扇入时不会使语义更加复杂。
6. Instead of having operation attributes that alter the behavior of the operation significantly, have separate operations, so that it is simple and clear to a client which semantics the Printer is supporting (by querying the "operations-supported" attribute) and it is simple to describe the capabilities of a Printer implementation in written documentation (just list the optional operations supported).
6. 与其使用显著改变操作行为的操作属性，不如使用单独的操作，这样客户端就可以简单明了地了解打印机支持的语义（通过查询“支持的操作”属性）在书面文档中描述打印机实现的功能很简单（只需列出支持的可选操作）。
7. Need a Printer Operation to prevent a Printer object from accepting new IPP jobs, but currently accepted jobs continue unaffected to be scheduled and processed. Need a companion one to restore the Printer object to accept new IPP jobs.
7. 需要打印机操作以防止打印机对象接受新的IPP作业，但当前接受的作业继续不受影响地进行计划和处理。需要一个伴奏来恢复打印机对象以接受新的IPP作业。
Usage: Operator is preparing to take the IPP Printer out of service or to change the configuration of the IPP Printer.

Suggested name and operations: Disable-Device and Enable Device
建议的名称和操作：禁用设备和启用设备
9. Need a Printer Operation to stop the processing after the current IPP job completes and not start processing any additional IPP jobs (either by scheduling the jobs or sending them to the Output Device), but continue to accept new IPP jobs. Need a companion operation to start processing/sending IPP jobs again.
9. 需要打印机操作在当前IPP作业完成后停止处理，并且不开始处理任何其他IPP作业（通过调度作业或将作业发送到输出设备），但继续接受新的IPP作业。需要伴随操作才能再次开始处理/发送IPP作业。
Usage: Operator wants to gracefully stop the IPP Printer at the next job boundary. The Pause-Printer-After-Current-Job operation is also invoked implicitly by the Deactivate-Printer and the Shutdown-Printer Operations.
用法：操作员希望在下一个作业边界正常停止IPP打印机。停用打印机和关闭打印机操作也会隐式调用当前作业操作后暂停打印机。

建议的名称和操作：在当前作业后暂停打印机，（IPP/1.1）恢复打印机
10. Need a Device Operation to stop the processing the current job "immediately", no matter what protocol. Its like the Pause button on the Output Device. This operation is for emergencies. The stop point depends on implementation, but can be mid page, end of page, end of sheet, or after a few sheets for Output Devices that can't stop that quickly. The paper path isn't run out. Need a companion operation to start processing the current any-protocol job without losing any thing.
10. 需要一个设备操作来“立即”停止处理当前作业，无论采用何种协议。它就像输出设备上的暂停按钮。这次行动是为了紧急情况。停止点取决于实现，但对于无法快速停止的输出设备，可以是页面中间、页面结束、页面结束或几页之后。纸张路径没有用完。需要一个伴随操作来开始处理当前的任意协议作业，而不会丢失任何东西。
Usage: Operator sees something bad about to happen, such as the paper is about to jam, or the toner is running out, or the device is overheating or wants to add more paper.

Usage: This allows an operator to reconfigure the Output Device in order to let jobs that are held waiting for resources, such as special media, get a chance. Then the operator uses another operation after reconfiguring. He repeats the two operations to restore the Output Device to its normal media.
用法：这允许操作员重新配置输出设备，以便让等待资源（如特殊介质）的作业获得机会。然后，操作员在重新配置后使用另一个操作。他重复这两个操作，将输出设备恢复到其正常介质。

Suggested name and operations: Pause-Device-After-Current-Job, Resume-Device
建议的名称和操作：在当前作业后暂停设备，恢复设备
14. Need a Printer Operation that combines Disable-Printer, Pause-Printer-After-Current-Job, and rejects all other Job, Printer, and Device Operations, except Job and Printer queries, System Administrator Set-Printer-Attributes, and the companion operation to resume activity. In other words, this operation makes the Printer a read-only object in a graceful manner for end-users and the operator.
14. 需要一个打印机操作，该操作结合了禁用打印机、在当前作业后暂停打印机以及拒绝所有其他作业、打印机和设备操作（作业和打印机查询除外）、系统管理员设置打印机属性以及恢复活动的伴随操作。换句话说，对于最终用户和操作员来说，此操作使打印机以优雅的方式成为只读对象。

16. Need a Printer Operation to recover from the IPP Printer software that has gotten confused (run out of heap memory or gotten into a state that it doesn't seem to be able to get out of). This is a condition that shouldn't happen, but does in real life. Any volatile information is saved if possible before the software is re-initialized. No companion operation is needed to undo this. We don't want to go back to the "confused" state :-).
16. 需要一个打印机操作来从IPP打印机软件中恢复，该软件已变得混乱（堆内存耗尽或进入无法摆脱的状态）。这是一种不应该发生的情况，但在现实生活中确实会发生。如果可能，在重新初始化软件之前，会保存任何易失性信息。撤消此操作不需要伴随操作。我们不想回到“困惑”状态：-）。

Need a Device Operation to recover from the Output Device hardware and software that has gotten confused (gotten into a state that it doesn't seem to be able to get out of, run out of heap memory, etc.). This is a condition that shouldn't happen, but does in real life. This is the same and has the same options as the Printer MIB reset. No companion operation is needed to undo this. We don't want to go back to the "confused" state :-).
17. 需要一个设备操作来从混乱的输出设备硬件和软件中恢复（进入似乎无法取出、堆内存耗尽等状态）。这是一种不应该发生的情况，但在现实生活中确实会发生。这与打印机MIB重置相同，并且具有相同的选项。撤消此操作不需要伴随操作。我们不想回到“困惑”状态：-）。
Usage: The Output Device has gotten confused or need resetting to some initial conditions.
用法：输出设备变得混乱或需要重置为某些初始条件。
Suggested name and operation: Reset-Device
建议名称和操作：复位装置
18. Need a Printer Operation to put the IPP Printer object out of business with no way in the protocol to bring that instantiation back to life (but see Startup-Printer which brings up exactly one new instantiation to life with the same URL). Any volatile information is saved if possible.
18. 需要一个打印机操作来停止IPP打印机对象的业务，协议中没有办法使该实例化恢复生命（但请参阅Startup Printer，它使用相同的URL将一个新实例化恢复生命）。如果可能，将保存任何易失性信息。

4 IANA Considerations
4 IANA考虑因素
This document does not define anything to be registered. When a document is produced that defines operations that meet the requirements in this document, those operations will be registered according to the procedures in [RFC2911] section 6.4.
本文档未定义任何要注册的内容。当生成定义满足本文件要求的操作的文件时，将根据[RFC2911]第6.4节中的程序对这些操作进行登记。
5 Internationalization Considerations
5国际化考虑
This document has the same localization considerations as the [RFC2911].
本文件具有与[RFC2911]相同的本地化注意事项。
6 Security Considerations
6安全考虑
This document defines the requirements for operations that are intended to be used by an operator or system administrator. These operations, when defined, would affect how the Printer behaves and establish policy and/or operating behavior that ordinary users shouldn't be able to perform. Printer implementations that support such operations should authenticate users and authorized them as being an operator or a system administrator for the system. Otherwise, unprivileged users could affect the policy and behavior of IPP Printers, thereby affecting other users. Similarly clients that supports such operations should be prepared to provide the necessary authentication information. See the security provisions in [RFC2911] for authentication, such as TLS.
本文件规定了操作员或系统管理员拟使用的操作要求。定义这些操作后，将影响打印机的行为，并建立普通用户无法执行的策略和/或操作行为。支持此类操作的打印机实现应该对用户进行身份验证，并将其授权为系统的操作员或系统管理员。否则，非特权用户可能会影响IPP打印机的策略和行为，从而影响其他用户。类似地，支持此类操作的客户端应该准备好提供必要的身份验证信息。有关身份验证，如TLS，请参见[RFC2911]中的安全规定。

The "Design Goals for an Internet Printing Protocol" document takes a broad look at distributed printing functionality, and it enumerates real-life scenarios that help to clarify the features that need to be included in a printing protocol for the Internet. It identifies requirements for three types of users: end users, operators, and administrators. It calls out a subset of end user requirements that are satisfied in IPP/1.0. A few optional operator operations have been added to IPP/1.1.
“Internet打印协议的设计目标”文档广泛介绍了分布式打印功能，并列举了有助于澄清需要包含在Internet打印协议中的功能的实际场景。它确定了三类用户的需求：最终用户、操作员和管理员。它列出了IPP/1.0中满足的最终用户需求的子集。IPP/1.1中增加了一些可选的操作员操作。
The "Rationale for the Structure and Model and Protocol for the Internet Printing Protocol" document describes IPP from a high level view, defines a roadmap for the various documents that form the suite of IPP specification documents, and gives background and rationale for the IETF working group's major decisions.
“互联网打印协议的结构、模型和协议的基本原理”文件从高层次的角度描述了IPP，定义了构成IPP规范文件套件的各种文件的路线图，并为IETF工作组的主要决策提供了背景和基本原理。
The "Internet Printing Protocol/1.1: Model and Semantics" document describes a simplified model with abstract objects, their attributes, and their operations that are independent of encoding and transport. It introduces a Printer and a Job object. The Job object optionally supports multiple documents per Job. It also addresses security, internationalization, and directory issues.
“Internet Printing Protocol/1.1：模型和语义”文档描述了一个简化模型，其中包含独立于编码和传输的抽象对象、属性及其操作。它引入了打印机和作业对象。作业对象可以选择为每个作业支持多个文档。它还解决了安全性、国际化和目录问题。
The "Internet Printing Protocol/1.1: Encoding and Transport" document is a formal mapping of the abstract operations and attributes defined in the model document onto HTTP/1.1 [RFC2616]. It defines the encoding rules for a new Internet MIME media type called "application/ipp". This document also defines the rules for transporting over HTTP a message body whose Content-Type is "application/ipp". This document defines the 'ippget' scheme for identifying IPP printers and jobs.
“Internet打印协议/1.1：编码和传输”文档是模型文档中定义的抽象操作和属性到HTTP/1.1[RFC2616]的正式映射。它定义了名为“应用程序/ipp”的新Internet MIME媒体类型的编码规则。本文档还定义了通过HTTP传输内容类型为“application/ipp”的消息体的规则。本文件定义了用于识别IPP打印机和作业的“ippget”方案。
The "Internet Printing Protocol/1.1: Implementer's Guide" document gives insight and advice to implementers of IPP clients and IPP objects. It is intended to help them understand IPP/1.1 and some of the considerations that may assist them in the design of their client and/or IPP object implementations. For example, a typical order of processing requests is given, including error checking. Motivation for some of the specification decisions is also included.
“互联网打印协议/1.1：实施者指南”文件为IPP客户端和IPP对象的实施者提供了见解和建议。它旨在帮助他们理解IPP/1.1以及一些可能有助于他们设计客户端和/或IPP对象实现的注意事项。例如，给出了处理请求的典型顺序，包括错误检查。还包括一些规范决策的动机。
The "Mapping between LPD and IPP Protocols" document gives some advice to implementers of gateways between IPP and LPD (Line Printer Daemon) implementations.
“LPD和IPP协议之间的映射”文档为IPP和LPD（Line Printer Daemon）实现之间网关的实现者提供了一些建议。
The "IPP Event Notifications and Subscriptions" document defines an extension to IPP/1.0 [RFC2566, RFC2565] and IPP/1.1 [RFC2911, RFC2910]. This extension allows a client to subscribe to printing related Events and defines the semantics for delivering asynchronous
“IPP事件通知和订阅”文档定义了对IPP/1.0[RFC2566，RFC2565]和IPP/1.1[RFC2911，RFC2910]的扩展。此扩展允许客户机订阅与打印相关的事件，并定义用于传递异步消息的语义
Event Notifications to the specified Notification Recipient via a specified Delivery Method (i.e., protocols) defined in (separate) Delivery Method documents.
通过（单独的）交付方法文档中定义的指定交付方法（即协议），向指定的通知收件人发送事件通知。
