The Printer Working Group Standard for
Media Standardized Names

Abstract: This document specifies standard names to be used to indicate media types, media colors, and media sizes in other standards.  These lists of names are a superset of the names that are currently presented in the Printer MIB [PRT-MIB] and the IPP Model and Semantics [IPP-MOD] documents.  It is intended to supplement the currently defined lists as well as to provide a normative reference for all subsequent standards.

1	Introduction
Media types, media colors, and media sizes have been defined in many previously published standards related to printing.  Examples are the ISO Document Printing Application [DPA], the IEEE Transport Independent Printer/System Interface [TIP/SI], the IETF Printer MIB [PRT-MIB], and the IETF Internet Printing Protocol [IPP-MOD].  Although there is a high degree of commonality in the set of media types, colors, and sizes presented in these documents, they do not represent a uniform set.  Several other standard developments, in process prior to the creation of this standard, also have a need for media type, color, and size definitions.  Also there is a large body of existing computer printing system practice based upon PPD and GPD files to describe a Printer’s capabilities that include media type, color, and size.  Thus this standard is a response to an urgent need to define a complete set of media types, colors, and sizes, in an independent document, that can be used as a normative reference by other standards.
This standard is the result of extensive research to obtain an exhaustive list.  It provides a superset of the media types, colors, and sizes currently defined in the previously listed specifications.  This standard is intended to update the list that is currently presented in the Printer MIB and the IPP Model and Semantics [IPP-MOD] specification and it also can be referenced by future standards.  This document will be periodically updated to include any additional types, colors, and sizes, as required.
1.1	Scope
This document defines media types, media colors, and media sizes only.  Other media attributes such as name, weight, or opacity are not included at this time, though they may be added in the future, if the need arises.    
No provisions are included to specify roll paper sizes.  All media sizes defined represent a cut sheet.  Media that is printed and then cut by the printing device can use this standard only to define the final size.  
The color attribute that is included in a portion of the Media Name entries in both the Printer MIB and IPP are included as a separate independent set of Color Names in this specification.  
The media size dimensions that are defined in this document are independent of the media feed direction (i.e. short edge feed or long edge feed) or printing orientation (i.e. portrait or landscape).  Both of these parameters are best handled by unique attributes rather than overloading the media size attribute.
The intent of the names defined in this standard is for program to program communication, not for internal use within a program or for program to human display.  Examples include: (1) from a Printer to client software, (2) from client software to a Printer, and (3) from a printer data description file to client software.  Typically a client will localize these names to the human language and units of the user before displaying them to the user.  However, when a client encounters a name that it does not recognize, these names have been defined so that they can be displayed to the user as a Fallback presentation.  Some clients may omit localization in order to simplify implementation of displaying names to users.

The Media Size Self-Describing Name deserves special mention.  It contains both a media size name and the dimensions, in case the receiver does not recognize the media size name.  Such a receiver can then parse the Media Size Self-Describing Name and discover the intended dimensions of such an unrecognized media.  These names have also been defined to facilitate parsing and/or Fallback presentation of either the media size name part and/or the dimensions part.
2	Terminology
This glossary defines certain terms used in this specification which may not be generally familiar or which may be used with very specific meaning.  These definitions are not intended to be absolute but do reflect the use of the terms within this specification.
ABNF  (Augmented Backus-Naur Form) [ABNF]  A formal meta-syntax used to express content-free grammars.  ABNF is commonly used in internet protocol specifications.  
Alias  An alternative name that is commonly used to mean the same as a name standardized in this document, but which is not defined for a use that conforms to this standard.
ASCII  American Standards Code for Information Exchange as defined in ANSI X3.4-1986, “Coded Character Set - 7-bit American Standard Code for Information Interchange (ASCII)."  Defines a character set encoding with printable characters defined in the range 0x21 to 0x7E and the SPACE character (0x20).  Other encoded values must not be used.
IETF  Internet Engineering Task Force.  A volunteer group that develops and approves standards that are relative to the Internet.
ISO  International Organization for Standardization.  
Legacy Name  A name used in the same contexts as the names defined in this standard, but which is deprecated from use when conforming to this standard.  This name is provided for historical context.
media  The consumable upon which the marking engine marks so as to form a text and/or pictorial image, typically paper.
Media Color Name  The human readable name used to identify the color of the media.  Examples: ‘white’, ‘red’, ‘ivory’.
Media Dimensions  The short and long dimensions of the media.
media finish  An adjective that describes the surface texture of the medium.  In most cases the texture is obtained by the application of a coating.  Examples:  ‘glossy’, ‘matte’.
Media Name  The human readable name used to identify media that possess the same characteristics and to distinguishes the media from others with different characteristics for the context in which the Media Name is used.  Examples:  ‘iso-a4-white’, na-letter-transparency’, ‘monarch-envelope’.  This standard does not define Media Names.
Media Size Name   The human readable name that identifies a particular media size.   Examples: ‘iso_a4’, ‘na_letter’, ‘monarch’.
Media Size Self-Describing Name (or Media Size for short)  An ASCII string that contains a Media Size Name and the Media Dimensions that correspond to the Media Size Name.  Examples: ‘iso_a4_210x297mm’, ‘na_letter_8.500-x11in’, ‘na_monarch_3.875x7.5in’.
Media Type Name  The human readable name that identifies a particular medium type, i.e., the predominate characteristic of the media.  Examples:  ‘stationery’, ‘transparency’, ‘envelope’.
3	Media Type Names
The standardized Media Type Names are defined in Table 1.  The base set of these names is derived from the Printer MIB [PRT-MIB] and "Media Features for Display, Print, and Fax" [FEATURES] documents. Additional values MAY be registered according to both [TAG-REG] and [IPP-MOD].  
For Media Types that produced using a coating or special process, the coating or process may only be applied to one side.  The Media Type Names defined in this standard do not define either one sided or two sided conditions.  For situations where this information needs to be presented, an implementation specific method  must be used.
The Ref column indicates the source document(s) for the name.  
1  =  The Printer MIB [PRT-MIB].
3  =  Media Features for Display, Print, and Fax [FEATURES].
5  =  IPP Production Printing Attributes [IPP-PROD]   The name in this document is derived from the “media-front-coating” and “media-back-coating” member attributes by adding the ‘photographic-’ prefix to the IPP keyword values. 
6  =  IPP Production Printing Attributes [IPP-PROD]   The name in this document is derived from the “media-pre-printed” member attributes by adding the ‘stationery-’ prefix to the IPP keyword values.

3.1	Custom Media Type Names 
Media Type Names may be locally extended using a Custom Media Type Name, without an update to this specification.  The format is defined by the following ABNF:
   custom-media-type-name = "custom-media-type-" type-name
   type-name = lowalpha *( lowalpha | digit | "-" )
   lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" |
              "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" |
              "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z"
   digit    = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
Example, preprinted stationery for company XYZ:   custom-media-type-xyz-letterhead  
4	Media Color Names
Table  defines the standardized Media Color Names. These names are derived primarily from the Printer MIB [PRT-MIB], prtInputMediaColor standard values. One major difference from the Printer MIB, the name 'transparent' has been replaced by 'no-color'.  This allows use of a color attribute with the media type ‘transparency’ as defined in Table .
The Ref column indicates in which document(s) the identical name appears.
1  =  The Printer MIB [PRT-MIB].
5  =  IPP Production Printing [IPP-PROD], “media-color” member attribute keywords.

ivory	5	The specified media is ivory.	
orange	5	The specified media is orange.	

4.1	Custom Media Color Names 
Media Color Names may be locally extended using a Custom Media Color Name, without an update to this specification.  The format is defined by the following ABNF:
   custom-media-color-name = "custom-media-color-" color-name
   color-name = lowalpha *( lowalpha | digit | "-" )
   lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" |
              "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" |
              "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z"
   digit    = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
Example, media of the color mauve:   custom-media-color-mauve  
5	Media Size Self-Describing Names
The media size specifications defined in this document, labeled as Media Size Self-Describing Names, are cross indexed to Legacy Names and Alias (common) names.  The Legacy Names define the names currently used in the ISO DPA, Printer MIB, or IPP documents.  A reference column is included in the tables to indicate which of these three documents contain the Legacy Name.
Ref column entry definitions:
1 =  Printer MIB [PRT-MIB] and ISO DPA [DPA].  (Both documents contain an identical set.)
2 =  IPP [IPP-MOD].
4 =  ASME Y14  [ASME-IN]
5 =  ASME Y14.M  [ASME-M]
5.1	Media Size Self-Describing Name Format
This specification defines a new Media Size Self-Describing Name format that is recommended to be used by all new implementations.  This new format has the Media Size Name and the Media Dimensions embedded within the string and allows a device to operate without a Media Size Name to Media Dimensions table.  The Media Size Self-Describing Name format is structured as follows using ABNF:
   media-size-self-describing-name = 
( class-in "_" size-name "_" short-dim "x" long-dim "in" ) |
( class-mm "_" size-name "_" short-dim "x" long-dim "mm" )
   class-in = "custom" | "na" | "asme" | "roc" | "oe" 
   class-mm = "custom" | "iso" | "jis" | "jpn" | "prc" | "om"
   size-name = ( lowalpha | digit ) *( lowalpha | digit | "-" )
   short-dim = dim
   long-dim = dim
   dim = integer-part [fraction-part] | "0" fraction-part
   integer-part = non-zero-digit *digit
   fraction-part = "." *digit non-zero-digit
   lowalpha = "a" | "b" | "c" | "d" | "e" | "f" | "g" | "h" | "i" |
              "j" | "k" | "l" | "m" | "n" | "o" | "p" | "q" | "r" |
              "s" | "t" | "u" | "v" | "w" | "x" | "y" | "z"
   non-zero-digit = "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
   digit    = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9"
The above ABNF is current as of the date of publication this document.  Implementers should be aware that the currently defined class names may be expanded in the future to cover new groups of media sizes.  Thus client parser implementations that are developed using this ABNF should accept class names that are not currently represented in this list.  The latest ABNF, which shall always be the proper reference for use within this standard, may be obtained at:
ftp://ftp.pwg.org/pub/pwg/standards/pwg5101-abnf.txt
5.1.1   class-xx   This string part is present to indicate the name space or jurisdiction for the size name in order to prevent name clashes.  Currently defined values are "na" for North America, "asme" for American Society of Mechanical Engineers, "iso" for the International Standards Organization, "jis" for Japanese Information Standard, "jpn" for Japan, "prc" for People's Republic of China, "roc" for Republic of China (Taiwan), "oe" for other English, and "om" for other metric.  "custom" defines a unique class name that allows site and vendor unique size definitions, see paragraph 5.1.7.  New class names must conform to the following ABNF:
  class-name = ( lowalpha | digit ) *( lowalpha | digit | "." )
5.1.2   size-name   This string provides a textual description of the media size.  It is normally derived from the Legacy or Alias name associated with the media size.  The size-name can consist of multiple parts, with each part separated by a hyphen (0x2D).
5.1.3   short-dim and long-dim   These values define the media size.  The short-dim is always the smaller of the two dimensions.  The dimensions are presented in decimal format to as many places as necessary to define the size.  Trailing zeros must never be used if a decimal portion is present.
5.1.4 For interchange between programs, the dimensions presented in this standard must never be converted to the another system of units, but must remain as defined in this standard.  Furthermore, an identical size shall never appear in this standard with different units. Programs may convert the dimensions to other units when displaying these names to human users and for internal use, both of which are outside the scope of this standard.
The common usage of some names may represent several physical sizes (e.g. folio, quarto, foolscap, and executive).  To avoid naming conflicts, a hyphenated identifier must be used to link the names to a specific size.  Only one of the possible sizes may use the name without a hyphenated identifier.
5.1.5   General 
The Media Size Self-Describing Name shall not contain any space characters (0x20).
Wherever possible, the Media Size Self-Describing Name has been derived from the Legacy Name.  In many cases the 'class_size-name' portion is identical to the Legacy Name.  In the  remaining cases, the 'class' portion must be ignored to match the Legacy Name.
5.1.6  Examples:  
The letter size (8.5 inches by 11 inches) used in North America:    na_letter_8.5x11in
The iso A4 size (210 mm by 297 mm) used in metric countries:    iso_a4_210x297mm
5.1.7  Custom Media Size Self-Describing Names 
The "class-custom" allows extensibility of the media size set without an update to this specification.  This feature is primarily intended for special media sizes that are used at a minimum number of locations.  Size names that use the "custom" prefix are never registered or published within this standard.
5.2	Reserved Size Names
The size-name "max" shall be reserved to indicate an upper size limit of either a device or application.  Also, the size-name "min" shall be reserved to indicate a lower size limit.  Example: For a device that can process forms as small as 2 x 3 inches to 18 x 36 inches:
custom_max_18x36in   and  custom_min_2x3in
5.3	Conventions for the Tables
The rest of this section contains the tables of Media Size Self-Describing Names.  Within a table entries from different sources are grouped together.  The entries in these groups are arranged in order of increasing size of the smaller dimension.  
The presence of “(envelope)” in the Alias column indicates this size is also commonly used for envelopes.  It does not imply that this size is only available as an envelope media type.

6	Conformance Requirements
The Media Type Names, Media Color Names, and Media Size Self-Describing Names defined in this document are recommended for any future specifications that have a need for media type, media color, or media size definitions respectively.  The proper procedure for including these names is to simply reference this specification as the definition and source of the media types, colors, or sizes with the clause "or subsequent revisions".  In this manner, any updates to this document are automatically included in the referencing specification.
Media Names defined in this specification are presented using lower case characters. Other referencing standards may impose case sensitive rules if necessary. For interoperability and implementation efficiency, this standard strongly recommends these names be used in the lower case form defined in this document.
The Media Size Self-Describing Names defined in this document contains significantly more information than is found in many current standards.  Conformance to this standard does not require that all parts of the Media Size Name be represented.  It is conformant to only use the "size-name" or the "class_size-name" portion.  It is also acceptable to replace the underscore separator between the "class" and "size-name" with a hyphen.  
7	Registration Procedures for Additional Names
This standard will be republished as needed, but not more often than once a year.  In the interim, new Media Type Names, Media Color Names, and Media Size Self-Describing Names can be registered and have the same status as the standardized names in this document.

Requests are to be submitted by email to the pwg@pwg.org mailing list.  The proposed name must include a description and must follow the same patterns as the standardized names currently included in the standard.  Any name submitted without a description will be rejected.  The process is identical to the PWG Draft standard approval process (see ftp://ftp.pwg.org/pub/pwg/general/pwg-process.pdf). 
After approval, the name and description will be available, with the Media Standardized Names standard at:  ftp://ftp.pwg.org/pub/pwg/standards/.  The file name for the new name will be of the form pwg5101.1-xxx, to indicate it is an addition to the pwg5101.1 standard.  Such registrations will have the same status as all names in the published standard.
All names that are registered in this manner will be included in the next revision of the standard and the included registrations will be removed from the directory.
8	Internationalization Considerations
All standardized textual strings must be represented as US-ASCII character codes and local translations must never be performed.  Custom sizes, if limited to local use, may be represented using any desired character set.
9	Security Considerations
This specification will have no impact on the security burden of or potential threats to the importing system.

12	Annex A: Media Names Usage in Existing Standards (informative)
This appendix provides a cross reference between the usage of media names in existing standards and the appropriate group in this document.  Future revisions of these standards should reference this document as the source of this information.  No attempt will be made to update this appendix when additional standards reference this document; the existing references will suffice.

Notes:
1.	Printer MIB size names do not include the dimensions part.  The dimension are represented by the objects prtInputMediaDimFeedDirDeclared, prtInputMediaDimXFeedDirDeclared, prtInputMediaDimFeedDirChosen, and prtInputMediaDimXFeedDirChosen.
2.	The Production Printing Attributes referenced are all member attributes of the "media-col" Job Template attribute.
3.	The media sizes are included in the “media-size” member attribute of the “media-col” Job Template attribute as a pair of numeric values (mm/100).
13	Annex B: Parser Considerations for the Media Size Name (informative)
Special consideration needs to be made during the development of a parser for the Media Size Name.  Since additional "class" names and "size-names" may be defined in the future, in many cases the parser must not be strictly conformant to the ABNF.  The following is intended to provide guidelines for the development of client parsers and device parsers:
Client Parsers:  There are several degrees of client which display something to the user for selection and MAY format documents (where it would need to know the dimensions):
a. non-formatting client:  In this case, the parser treats the string as a unit and might simply display it to the user as is, no parsing is required. If the parser localizes and finds a string that it doesn't recognize, then it can just display the entire string as received, or perhaps breaks it up into separate pieces separated by a space.  Such a client most likely doesn't format documents, so it will not even care about the dimensions, only the user and Printer do.
b. client does formatting:  Now the client will separate the class field, the name field, and the dimension field. The class and name fields may be displayed as is or localized, and the dimensions are converted to the units preferred by the user.  If a class or name field isn't recognized, it will be displayed as is, perhaps with underlines replaced by spaces.  The dimensions will also be converted to the internal units for formatting documents.
Device Parsers:  On the Printer side, there are two cases to consider, the one that doesn't support client's inventing custom sizes and the one that does.  If the Printer displays media sizes to an operator or on an op panel, then that parser code has the same problems as the client (see above).
a. device doesn't support client-defined custom sizes:  In this situation the parser doesn't even need to parse the string.  It simply compares the entire string with a list of supported strings, including system administrator defined custom sizes.  If there isn't a match, the Printer doesn't support that requested size and takes the appropriate action.  
b. device supports client-invented custom sizes:  Here the Printer parser must look at the class field for "custom", then parse the dimensions and check for a valid range and then possibly convert to the Printer's internal units.
