3、EE Standard for Information TechnologyTransport IndependentPrinter/System Interface (TIP/SI.)Local area networks are increasingly becoming the most popular means of interconnecting devices within acorporation. With costs per connection coming down, this trend shows no sign of abating. As networks gr

4、ow larger,more computers and printers will be interconnected. Any weaknesses in network printing will only be magnified asmore devices are made to communicate.The absence of feedback from existing printers causes many problems in todays network environment. For example,a user could be submitting a j

5、ob to a remote printer. If that printer is low on toner, most printers today do not have thecapability to inform users about this condition. Additionally, if the job is large, the user risks having to wait until thejob is finished before finding out that the output is incorrect. The resulting waste

6、of paper, toner, and time could besignificant when calculated over a period of time on a large network.Standardized feedback information from a printer would solve this problem. By the use of this standard, when a printerrecognizes a condition that would prevent it from accurately printing a job, it

7、 can send a standardized message to a hostcomputer that is monitoring network printing. Upon receipt of this message, the host could then send a message to theuser who submitted the job, informing him or her of the error condition. The user could then redirect a job to a moreappropriate printer or u

8、ndertake action to correct the defect at the target printer. When projected over a period of timeand a large number of network users, the resulting monetary savings could be substantial.The example shown above is just one of many error conditions that could occur when printing either on a standalone

9、computer or over a network. By using this standard format for exchanging information between the printer and host,software vendors, network suppliers, and printer manufacturers will now be able to greatly improve the efficiency ofnetwork printing.At the time this standard was completed, the key cont

24、ndard for Information TechnologyTransport Independent Printer/System Interface (TIP/SI)1. Overview1.1 ScopeA standard protocol for the control of printers that is independent of the underlying data stream or page descriptionlanguage (PDL) used to create the printed page is defined in this standard.

25、This protocol is usable by all classes ofprinters. The scope of this standard is limited to management and control of printers and does not include managementor control of a printing system or subsystems.1.2 PurposeThere is currently no defined, independent standard for controlling printers. Each ve

26、ndor builds some control into theunderlying PDL or data stream. Without an independent, openly defined protocol, applications and operating systemscannot automatically determine the type of printer being addressed. This protocol will provide a minimumimplementation subset that will allow automatic i

27、dentification and configuration of printers and vendor extensibility toprovide for growth and product differentiation.1.3 ObjectivesThis standard defines a protocol for communications between a host and printer. Its intent is to provide a standardmethodology for software developers, computer vendors

28、, and printer manufacturers that facilitates the orderlyexchange of information between printers and host computers. A minimum set of functions that permit meaningfuldata exchange is defined. Thus, this standard establishes a foundation upon which compatible applications, computers,and printers can

29、be developed, without compromising an individual organizations desire for design innovation. Thefollowing objectives accompany this standard:a) To simplify the printer driver development process by defining a standard set of command/responsetransactions between the host computer and printer.b) To ac

30、celerate the development of communicating printers by providing a robust protocol that can beimplemented in phases ranging from basic to extended functionality.c) To ease customers printing problems (especially over networks) by accelerating the availability ofcommunicating printers and compatible h

31、ost software.2 Copyright 1997 IEEE All Rights ReservedIEEE Std 1284.1-1997 IEEE STANDARD FOR INFORMATION TECHNOLOGY-d) To assist software developers in minimizing time to market by establishing a base set of functions that ensurea minimum level of communications between the host and printer.e) To fa

32、cilitate the creation of powerful network print management software by defining transactions that workacross a wide range of printers.f) To enable the creation of standard control/communications firmware that can be included in many peripheraldevices.g) To create a standard methodology for host and

33、printer communications that is independent of the transportmechanism used between devices.h) To enhance the management of printers in networks by providing a mechanism for printers to readily providetheir status and configuration to the host application.i) To permit design innovation by providing fl

34、exibility within the specification for printer manufacturers toinclude extensions to the original set of guidelines.j) To ensure cross-platform host-to-printer communications by creating an operating system-independent set ofguidelines.The resultant protocol is PDL-independent with the capability of

35、 a printer to support multiple PDLs, all activeat the same time, if desired.2. Definitions, abbreviations, and acronyms2.1 DefinitionsThis clause provides certain terms and definitions used in this specification that may not be generally familiar or thatmay be used with a very specific meaning. Thes

36、e definitions are not intended to be absolute but rather to give the senseof the terms as used in the context of this standard.2.1.1 American National Standard Code for Information Interchange (ASCII): In this standard, a text string ofsome arbitrary length. The text string may contain nonprintable

37、characters. The length must be stated in another field.The encoding is typically ISO 8859-1, but is specified by the Printer Language field in a “Request DeviceCharacteristicsRequest Summary” response. See also: IEEE Std 100-1996.2.1.2 ASCIIz: In this standard, an ASCII string concatenated with a NU

38、LL character.2.1.3 big endian: A term used to imply that bytes in a word and words in a double word are transmitted mostsignificant byte or word first in a serial stream of bytes.2.1.4 bit: A single binary integer. A set bit represents to a binary “1.” A cleared bit represents a binary “0.”2.1.5 bit

39、-encoded byte: A byte with a definition for each bit.2.1.6 bit-encoded word: A word with a definition for each bit.2.1.7 byte: An entity composed of 8 bits, used to define a unit element of memory or transmitted data. It is capable ofdescribing integers in the decimal range 128 to 127.2.1.8 command:

40、 A message from the host directed to the printer that may or may not include print data.2.1.9 connection: A parallel interface state that is outside the scope of this standard and is not defined herein. Thisstate is indicative of the state of the physical or logical connection between a host and the

41、 printer. Only in this state candata be transferred between a host and the printer.2.1.10 console language: The human language in which information is to be displayed on local or remote consoles.2.1.11 deprecated: Supported by predecessors to this standard but no longer used.2.1.12 desktop managemen

42、t interface (DMI): A facility, normally host resident, for handling and translating definedinterfaces for component information, event information, stored management information format (MIF) structures andmanagement information. In this context, a component is an integral device or product, such as

43、a printer; and event isan asynchronous alert or trap. The management information is used by an application such as a user managementCopyright 1997 IEEE All Rights Reserved 3TRANSPORT INDEPENDENT PRINTER/SYSTEM INTERFACE (TIP/SI) IEEE Std 1284.1-1997program, or may be converted for use by a network m

44、anagement facility. The desktop management interface iscontrolled by the Desktop Management Task Force.2.1.13 Desktop Management Task Force (DMTF): An association of software developers, host computer, andperipheral device manufacturers that promulgate a platform-independent interface standard for t

45、he management ofdesktop computers and the peripheral devices attached to such computers. In addition to defining the interfacesbetween components, the host-based service layer and management applications, the association supports thedevelopment of consistent management information format (MIF) struc

46、tures that define the significant manageableand status attributes of various components incorporated into desktop computers.2.1.14 document: An encoded, electronically transmittable image, set of images, or image-related information, whichis handled by the printer interface control unit.2.1.15 doubl

47、e word: A field composed of two words. In a message, the most significant word is transmitted/receivedfirst. It is capable of describing integers in the decimal range 2 147 483 648 to 2 147 483 647.2.1.16 duplex: For purposes of this standard, a type of printing that involves the process of creating

48、 images orimpressions on both sides of the printing media.2.1.17 facsimile: A process by which textual or pictorial images are communicated, typically but not exclusively, overtelephone lines. The images may be coded in raster or compressed raster format (such as CCITT group 3) or in a pagedescripti

49、on language such as Adobe PostScript. Facsimile typically operates down to the physical link level andincludes protocols providing control and addressing mechanisms specific to the media being used. This isdistinguished from the process of communicating similarly encoded images over local or wide area networks.However, both may be considered implementations of remote printing.2.1.18 feed direction: On most printers, the direction that the medium is moved through the marking engine. For aprinter in which the medium is not moved, the feed direction may be considered as al
