[IPP] Registration Template: "platform-shape (type2 keyword)" Printer Description attribute Michael Sweet msweet at apple.com Thu Jun 29 20:52:32 UTC 2017 All, Apple would like to register an additional IPP 3D Printer Description attribute called "platform-shape" which describes to the Client the overall shape of the build platform. The build platform described in the PWG 5100.21-2017: IPP 3D Printing Extensions v1.0 is a rectangle and the build volume a cuboid. However, some new 3D ("delta") printers use a 3-axis extruder positioning mechanism with a fixed elliptical build platform, forming a cylindrical build volume instead. The new "platform-shape (type2 keyword)" Printer Description attribute will be registered with two values: 'rectangle' and 'ellipse', with the default being 'rectangle' to conform to the definitions in 5100.21. The registration templates are as follows: Printer Description attributes: Reference ------------------------------ --------- platform-shape (type2 keyword) [APPLE20170629] Attributes (attribute syntax) Keyword Attribute Value Reference ----------------------- --------- platform-shape (type2 keyword) [APPLE20170629] ellipse [APPLE20170629] rectangle [APPLE20170629] _________________________________________________________ Michael Sweet, Senior Printing System Engineer
