************************************************************************ **** Revised 'printer:' template - 4 January 1998 - Ira E McDonald ***** ************************************************************************ *** ISSUES 1) Need to update for new SLP 'printer:' extension work on a raw TCP print protocol (in , 2 December 1998, by Mikael Pahmp, Axis, Sweden). Note, a concrete URL syntax for raw TCP printing is not proposed in Mikael's draft. 2) 'natural-language-configured' is MANDATORY for this template, to interpret the values of many string attributes (which can be tagged directly using IPP/1.0 'textWithLanguage' and 'nameWithLanguage'), but MISSING in Appendix E 'Generic Directory Schema' IPP/1.0 Model. 3) 'natural-language-supported' is MANDATORY for this template, to be comformant with RFC 2277 (IETF Policy on Character Sets and Languages, January 1998) and with common practice in directories, but OPTIONAL in Appendix E 'Generic Directory Schema' IPP/1.0 Model. 4) 'pages-per-minute-color' was NOT added, although proposed in email on the IPP WG mailing list. ------------------------------------------------------------------------ *** Change Log - High Level H1) Renamed all base attributes of the template, per latest draft of "Service Templates and service: Schemes", 13 November 1998: 'type' to 'template-type' 'version' to 'template-version' 'description' to 'template-description' 'url-syntax' to 'template-url-syntax' H2) Changed 'template-version' to '0.2' (from '0.1' in previous spec). H2) Deleted 'language = en' from template body, per the latest draft of "Service Templates and service: Schemes", 13 November 1998; H3) Renamed 'ippurl' element to 'ipp10url' (IPP/1.0) to allow supporting other IPP URL syntaxes in the future), per request of Bob Herriot (editor of IPP Encoding and Transport and prototype 'ipp:' specs). H4) Changed 'ipp10url' source reference to protocol spec, "IPP Transport and Encoding" [9], rather than (incorrect) model [3]. H5) Added a comment to each attribute, w/ the source attribute name in IPP (base document), Printer MIB (RFC 1759), or Salutation. H6) Revised various attribute descriptions for clarity or accuracy. (i.e., consistency with IPP specs). ------------------------------------------------------------------------ *** Change Log - Detail Level D1) Added 'printer-uri-supported' (ordered list) attribute, for use with (existing) 'uri-security-supported', per IPP Model, using '>' for ordered list delimiter character (safe around URIs), per comments from James Kempf on SLP mailing list. D2) Changed 'printer-uri-supported' and 'uri-security-supported' to mandatory attributes, per IPP Model, D3) Renamed 'name' to 'printer-name' and changed to mandatory, per IPP Model. D4) Renamed 'location' to 'printer-location' and changed to mandatory, per IPP Model. D4) Renamed 'description' to 'printer-info' and changed to optional, per IPP Model. D5) Renamed 'more-info' to 'printer-more-info' and changed to optional, per IPP Model. D6) Deleted 'concrete-protocols' and 'abstract-protocol' attributes, which were redundant with 'printer-uri-supported' (LPR is explicit, all others must be IPP, in some version). D7) Renamed 'make-model' to 'printer-make-and-model' and changed to mandatory, per IPP Model. D8) Renamed 'operator' to 'printer-current-operator' and corrected description to be single-valued, per Printer MIB. D9) Renamed 'service-person' to 'printer-service-person' and corrected description to be single-valued, per Printer MIB. D10)Added 'natural-language-configured' (it was already referred to to as the language of other attributes in the previous draft), and attribute descriptions were revised to clarify which attributes are interpreted via 'natural-language-configured', per IPP Model. D11)Revised 'natural-language-supported' (it relates to both error and status messages and directory attributes), BUT changed to mandatory, despite (conflicting) IPP Model. D12)Added 'charset-configured' (for consistency, although all SLP template attributes are always specified in UTF-8), and changed to optional, per IPP Model. D13)Revised 'charset-configured' and 'charset-supported', to mandate the use of the '(preferred MIME name)' values, and changed to optional, per IPP Model. D14)Revised 'document-format-supported', and changed to mandatory, per IPP Model. D15)Revised 'color-supported' to clarify that it covers ALL color capabilities, including highlight color printing, and changed to mandatory, per IPP Model. D16)Renamed 'finishing' to 'finishings-supported' and removed explicit staple positions, per IPP Model. D17)Renamed 'number-up' to 'number-up-supported', per IPP Model. D18)Renamed 'duplex-mode' to 'sides-supported' and changed to mandatory, per IPP Model. D19)Revised 'media-supported' to clarify that it contains ONLY the ISO 10175 media keywords, in fixed locale of 'en-US' (US English), and changed to mandatory, per IPP Model. D20)Revised 'media-local-supported' to clarify that it contains ONLY the site-specific media names, in 'natural-language-configured' locale, and changed to mandatory, per IPP Model. D21)Renamed 'resolution' to 'printer-resolution-supported', and clarified syntax to be an unordered list of three-tuples with each member of a three-tuple delimited by '>', per IPP Model. D22)Renamed 'print-quality' to 'print-quality-supported', per IPP Model. D22)Renamed 'copies' to 'copies-supported', per IPP Model. D23)Renamed 'job-k-octet-supported' to 'job-k-octets-supported', (typo in previous version of template), per IPP Model. D24)Added 'pages-per-minute' (proposed new attribute for IPP), per request of Angelo Caruso and IPP WG discussion. D25)Renamed 'delivery-orientation' to 'delivery-orientation-supported', to reflect capabilities (not current setting as in Printer MIB), per request of Tom Hastings and IPP WG discussion. D26)Added hyphens to 'delivery-orientation-supported' values (from Printer MIB) 'face-up' and 'face-down', for standard style. ------------------------------------------------------------------------ *** Corrected References (for full Internet-Draft) [3]--change date to November 1998 (latest draft) [4]--change date to November 1998 (latest draft) ------------------------------------------------------------------------ *** Additional References (for full Internet-Draft) [9]R.
