Printer Working Group Simple Job Ticket Version 1.0 (for consumer electronics printing) Technical Brief Status: Initial 10 May 2004
Abstract: This document defines the semantics and encoding for the PWG Simple Job Ticket v1.0 (SJT/1.0). A consumer electronics device (e.g., digital camera or cell phone) can transfer a standard SJT/1.0 job ticket via removable media (e.g., memory card or DVD), direct connect (e.g., USB or parallel), or network interface (e.g., IEEE 802.11 or Ethernet) to a print service or print device.
For industry coherence, this document imports the semantics (but not the encoding) of the Job and Document objects and selected attributes from the PWG Semantic Model [PWG5105.1].
In order to support inexpensive consumer electronics devices, this document defines a simple string encoding (non-XML) for the SJT/1.0, using minimal markup and tokenized (numeric) attribute names and values. This encoding also allows the inclusion of vendor extensions as well as other attributes from the complete PWG Semantic Model.

About the Printer Working Group
The Printer Working Group (or PWG) is a Program of the IEEE-ISTO. All references to the PWG in this document implicitly mean "The Printer Working Group, a Program of the IEEE ISTO." The PWG is chartered to make printers and the applications and operating systems supporting them work together better. In order to meet this objective, the PWG will document the results of their work as open standards that define print related protocols, interfaces, data models, procedures and conventions. Printer manufacturers and vendors of printer related software would benefit from the interoperability provided by voluntary conformance to these standards.
In general, a PWG standard is a specification that is stable, well understood, and is technically competent, has multiple, independent and interoperable implementations with substantial operational experience, and enjoys significant public support.

This document defines the semantics and encoding for the PWG Simple Job Ticket v1.0 (SJT/1.0), particularly for use by consumer electronics devices for interoperable printing.
Note: It is recommended that the reader first review the SJT/1.0 example in Appendix D and then the simple ABNF in Appendix C before reading the body of this document.
The SJT/1.0 defines a structured human-readable text syntax and encoding for three objects:
(1) JobTicket - an envelope for one Job and one or more Documents.
(2) Job - the description and processing instructions for a print job.
(3) Document - the description and processing instructions for a single document contained in a Job.
Both consumer electronics (CE) client devices (e.g., cell phones and digital cameras) and print devices (e.g., photo printers) have severely limited memory and CPU resources. The retail prices of these CE devices prohibits the inclusion of large RAM memory that is currently typical of desktop computers.
Therefore, the inclusion of an XML parser or of the many of long string constants necessary to parse any useful XML document instance is not feasible in CE devices. By extension, any printing solution based on Web Services (SOAP-based) is also not feasible in CE devices.
Any binary encoding of the information set supported by the SJT/1.0 would be only marginally more compact than the chosen string encoding. The additional cost and difficulty of development, debugging, and interoperability testing would not offset by the modest benefit of a binary encoding.
For inexpensive implementation, the SJT/1.0 adopts a simple, structured string encoding. This string encoding supports the inclusion of any vendor extension (a new attribute for one of the three standard objects) or any other attribute from the complete PWG Semantic Model [PWG5105.1].
Consistent with widespread industry practice, the Free Standards Group (FSG) Open Printing project Job Ticket API v1.0 [FSG-JTAPI] defines a JobTicket object as a container for a Job object and associated metadata (e.g., the author of the job ticket).
For industry coherence, the SJT/1.0 imports the JobTicket object and selected attributes from the FSG JTAPI/1.0 [FSG-JTAPI].
Since the Internet Printing Protocol v0.10 (IPP/1.0) [RFC2566] was first published (April 1999), IPP has become ubiquitous in network printers and print systems.
For industry coherence, the SJT/1.0 imports the Job object and selected attributes from the PWG Semantic Model [PWG5105.1]. However, for best interoperability, the SJT/1.0 imports Job attributes _only_ if they were originally defined in IPP/1.0 [RFC2566] (April 1999). The set of values defined for one Job attribute, "finishings", is updated to the larger set defined in IPP/1.1 [RFC2911] (September 2000).
Although over a dozen IETF or PWG "standards track" IPP extensions have been published, most are far less common in deployed network printers and print systems. Therefore, the IPP extensions are _not_ imported by the SJT/1.0 (except for the IPP Document Object [PWG5100.5]).
In IPP/1.0 [RFC2566] and IPP/1.1 [RFC2911], the operation attributes in all Document operations (e.g., Send-Document and Send-URI) are _not_ recorded. The IPP Document Object [PWG5100.5] (October 2003) remedies this shortcoming by introducing a first-class Document object.
Because the SJT/1.0 is entirely declarative (i.e., no network protocol binding is assumed or required), a Document object is absolutely necessary to support multiple documents in a single Job.
For industry coherence, the SJT/1.0 imports the Document object and selected attributes from the PWG Semantic Model [PWG5105.1] and their semantics defined in the IPP Document Object [PWG5100.5] (October 2003).
This document imports the definition and semantics of an Attribute from [RFC2911] and [PWG5105.1].
Note: The SJT/1.0 only defines and supports simple attributes (i.e., an SJT/1.0 attribute cannot be of datatype 'Object' or 'Collection').
An SJT/1.0 Consumer is the software in a target system that reads, decodes, validates, and processes an SJT/1.0 JobTicket instance.
This document imports the definition and semantics of an Object from [RFC2911] and [PWG5105.1].
An SJT/1.0 Producer is the software on a source system that builds, encodes, and writes an SJT/1.0 JobTicket instance.
The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as defined in [RFC2119].
Note: This document restricts the usage and meaning of the terms 'REQUIRED' and 'OPTIONAL' to define SJT/1.0 Producer conformance requirements for attributes.
Conforming SJT/1.0 Producers MUST supply this attribute.
Conforming SJT/1.0 Producers MAY supply this attribute.
The following diagram shows the object containment in the model:
|----------------------------------------------------------| | | | JobTicket (exactly one) | | - REQUIRED attributes | | - OPTIONAL attributes | | | | |------------------------------------------------------| | | | | | Job (exactly one) | | | - REQUIRED attributes | | | - OPTIONAL attributes | | | | | | |--------------------------------------------------| | | | | | | | Document (one or more) | | | | - REQUIRED attributes | | | | - OPTIONAL attributes | | | | | | | |--------------------------------------------------| | |------------------------------------------------------| |----------------------------------------------------------|
An SJT/1.0 JobTicket object is a container for job ticket processing or description attributes and exactly one embedded SJT/1.0 Job object.

Note: This document defines the JobTicket object as an extension to the PWG Semantic Model [PWG5105.1].
An SJT/1.0 Job object is a container for job processing or description attributes and one or more embedded SJT/1.0 Document object(s).

application/octet-stream
The syntax of 'application/octet-stream' SJT/1.0 JobTicket instances is defined in sections 6, 7, and 8 (Narrative) and Appendix A (ABNF) of this document.
Conformance: Conforming SJT/1.0 Producers that store SJT/1.0 JobTicket instances in text files, or transfer them in text streams, or submit them to network printers or print systems for plaintext viewing (not interpreting) MUST label them with a MIME Content-Type [RFC2046]:
text/plain; charset=UTF-8
The syntax of 'text/plain' SJT/1.0 JobTicket instances is defined in sections 6, 7, and 8 (Narrative) and Appendix A (ABNF) of this document.
Conformance: Conforming SJT/1.0 Producers that store SJT/1.0 JobTicket instances in text files, or transfer them in text streams, or submit them for plaintext printing MUST include a "charset" parameter of UTF-8 [RFC3629] in their MIME Content-Type [RFC2046]:
text/plain; charset=UTF-8
The section defines the datatypes used in SJT/1.0 defined attributes for JobTicket, Job, and Document objects. All of these datatypes are encoded in human-readable UTF-8 [RFC3629] text strings in the SJT/1.0 syntax.
ABNF Definition: enum-val = 1*DIGIT ; ASCII decimal string
The Enum datatype only allows one or more decimal digit characters. Valid enum values are defined in the 'Registry' clause in each attribute syntax definition.
ABNF Definition: integer-val = 1*DIGIT ; ASCII decimal string
The Integer datatype only allows one or more decimal digit characters. Valid integer ranges are defined in the 'Synposis' clause in each attribute syntax definition.
ABNF Definition:
list-val = DQUOTE list-string DQUOTE ; UTF-8 quoted list
; (without embedded DoubleQuote)
list-string = list-text *[COMMA list-text]
list-text = *(LCHAR / SP / XCHAR) ; List ASCII, Space, or UTF-8
COMMA = %x2C ; Comma
DQUOTE = %x22 ; DoubleQuote
SP = %x20 ; Space
LCHAR = %x21 / %x23-2B / %x2D-7E ; List ASCII (no Comma, DQuote)
XCHAR = %x80-FF ; UTF-8 character fragments
The List datatype allows a comma-delimited list of one or more text strings enclosed in DoubleQuote characters. Valid list elements are defined in the 'Synposis' clause and/or 'Description' clause in each attribute syntax definition.
ABNF Definition:
string-val = DQUOTE string-text DQUOTE ; UTF-8 quoted string
; (without embedded DoubleQuote)
string-text = *(TCHAR / SP / XCHAR) ; Visible ASCII, Space, or UTF-8
DQUOTE = %x22 ; DoubleQuote
SP = %x20 ; Space
TCHAR = %x21 / %23-7E ; Visible ASCII (no DoubleQuote)
XCHAR = %x80-FF ; UTF-8 character fragments
The String datatype allows any visible ASCII character, Space, or visible extended UTF-8 character (above 0x7F) enclosed in DoubleQuote characters. Valid string values MAY be defined or constrained in the 'Synposis' clause and/or 'Description' clause in each attribute syntax definition.
ABNF Definition:
uri-val = DQUOTE URI DQUOTE ; UTF-8 quoted URI
; (without embedded DoubleQuote)
URI = *(TCHAR) ; Visible ASCII (w/ hex escapes)
DQUOTE = %x22 ; DoubleQuote
TCHAR = %x21 / %23-7E ; Visible ASCII (no DoubleQuote)
The URI datatype encloses in DoubleQuote characters any visible ASCII character (except DoubleQuote) or visible extended UTF-8 character (above 0x7F) encoded as an [RFC2396] hex escape sequence. For example:
%E4%B9%82%2E
represents the single [ISO10646] character 'U+4E42'.
Valid URI schemes MAY be defined or constrained in the 'Synposis' clause and/or 'Description' clause in each attribute syntax definition.
See: "Escape Sequences" section 2.4 of [RFC2396].

The PWG secretary should durably register all of the SJT/1.0 object and attribute names, as well as all attribute enumerated values and their enum tags.
SJT/1.0 implementations conform to all the best practice recommendations in "IETF Policy on Character Sets and Languages" [RFC2277].
The charset of SJT/1.0 JobTicket instances is fixed as UTF-8 [RFC3629].
The natural language of the attributes in an SJT/1.0 JobTicket instance MAY be supplied by a conforming SJT/1.0 Producer using the JobTicket attribute "JobTicketNaturalLanguage".
The charset of the document data referenced in an SJT/1.0 Document instance MAY be supplied by a conforming SJT/1.0 Producer using the Document attribute "DocumentCharset".
The natural language of the document data referenced in an SJT/1.0 Document instance MAY be supplied by a conforming SJT/1.0 Producer using the Document attribute "DocumentNaturalLanguage".
Security considerations for the use of SJT/1.0 JobTicket instances (because they contain remote executable content) are the same as those for the 'application/postscript' MIME Content-Type defined in [RFC2046].
