32. 32 DLNA Printer (DMPr) Support Overview  DLNA Guidelines based on UPnP PrintEnhanced:1 Service and the W3C XHTML Print specification  The Key application optimized for DLNA is printing photos. –Of course other, more traditional, applications can be written to support a DMPr.  Printers combine Images with an XHTML template to create the printed page New DLNA Guideline Enhancements + XHTML Template Document = 2006 European Vacation

33. 33 DMPr Device DMPr Components New DLNA Guideline Enhancements UPnP PrintEnhanced:1 Service XHTML Print CSS Print UPnP Print Service Page Description Language CSS Print Enhanced Layout Extensions

34. 34 XHTML Print  XHTML Print is a print language based on HTML  The advantage of using an HTML like language is that it is very familiar to many content authors and there is an abundance of resources and tools available.  The model can be thought of as HTML uniquely tailored for printers and structured as an XML document.  The major difference from traditional printer languages (PCL, PostScript, …) is: –No driver needs to be installed to support a new printer. It was designed to be printer and manufacturer independent –Guarantees the content is printed but does not guarantee exact font matching, similar to HTML pages on the internet –Plain text commands – very easy to understand and program New DLNA Guideline Enhancements

35. 35 XHTML Photo Templates  Several photo templates were created or adopted by DLNA to make it very easy for new manufacturers to quickly add printing photos in the DLNA environment  The photo templates were designed to meet customer needs for a variety of photo printing scenarios. For example: –1 up Full bleed –3 up 4x6 –8 up wallet  There are 57 templates in all, regionalized for US, Asia, Japan, and EMEA and the most popular paper sizes in those regions New DLNA Guideline Enhancements

36. 36 Printer Image Memory  There is a wide range of printer capabilities taken into account for DLNA. One of the most critical is the amount of memory available on the printer available for image handling  The printer will indicate to the print controller 1 of 4 memory profiles that it is capable of supporting so that the controller can predictably and reliably send a print job to the printer and be guaranteed that no images will get lost Profile name Number of Images/Page Comment XHTML_ALLUnlimited XHTML_Complex100 Useful for index pages XHTML_PT8 Same as photo templates previously discussed XHTML_Baseline1 New DLNA Guideline Enhancements

37. 37 Printer Status  Printers are unique devices because of their familiar maintenance requirements – ink and paper  A well written printer application should indicate to the user when the printer needs intervention to continue  PrintEnhanced:1 defines State Variables to expose the current DMPr status to the Printer Controller  Some of the defined status indicators –Wrong Paper Loaded –Printer Error – Paper Jam, out of ink, etc. –Warning – Low on ink, low on paper, etc. –Content Not Found –Print Progress status – current page number. Useful to indicate current page/total pages. New DLNA Guideline Enhancements

38. 38 Printer Summary  UPnP PrintEnhanced was designed to make it extremely easy to add printing to your applications  Even though it feels like the same old printer, that is one of its strengths. The DLNA environment will open up a number of very interesting possibilities  Consider the new and interesting applications that it will enable for you and your customers New DLNA Guideline Enhancements
