About the IEEE-ISTO The IEEE-ISTO is a not-for-profit corporation offering industry groups an innovative and flexible operational forum and support services. The IEEE-ISTO provides a forum not only to develop standards, but also to facilitate activities that support the implementation and acceptance of standards in the marketplace. The organization is affiliated with the IEEE () and the IEEE Standards Association (. For additional information regarding the IEEE-ISTO and its industry programs visit: About the IEEE-ISTO PWG The Printer Working Group (or PWG) is a Program of the IEEE Industry Standards and Technology Organization (ISTO) with member organizations including printer manufacturers, print server developers, operating system providers, network operating systems providers, network connectivity vendors, and print management application developers. The group is chartered to make printers and the applications and operating systems supporting them work together better. All references to the PWG in this document implicitly mean “The Printer Working Group, a Program of the IEEE ISTO.” In order to meet this objective, the PWG will document the results of their work as open standards that define print related protocols, interfaces, procedures and conventions. Printer manufacturers and vendors of printer related software will 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.

IPP allows a print client to
(boolean) The "input-auto-scaling" member attribute specifies that the Printer should automatically determine the optimal "input-scaling-height" and "input-scaling-width". If specified with the 'true' value, Clients MUST NOT send and Printers MUST NOT accept the or "input-scaling-width" member attributes. The “input-attributes-supported” Printer attribute (section 7.4.8) specifies whether the Printer supports the "input-auto-scaling" member attribute. input-auto-skew-correction (boolean) The "input-auto-skew-correction" member attribute specifies that the Printer should automatically correct the scanned image for media skew. The “input-attributes-supported” Printer attribute (section 7.4.8) specifies whether the Printer supports the "input-auto-skew-correction" member attribute. input-brightness (integer(-100:100)) The "input-brightness" member attribute specifies the brightness of the scanned images. Negative numbers darken the images and positive numbers lighten the images. The “input-attributes-supported” Printer attribute (section 7.4.8) specifies whether the Printer supports the "input-brightness" member attribute. input-color-mode (type2 keyword) The "input-color-mode" member attribute specifies the color scanning mode for hardcopy documents in an Add-Document-Images (section 6.1) operation. The following values are currently defined: ‘auto’: Scans documents in ‘color’ and automatically reduces to ‘monochrome’ or ‘bi-level’ as appropriate ‘bi-level’: Scans documents using a thresholding mode or algorithm to produce a two tone image, typically black and white ‘color’: Scans documents in full color ‘monochrome’: Scans documents in a single color, typically grayscale The “input-color-mode-supported” Printer attribute (section 7.4.9) defines the supported values. Printers MUST support and Clients MUST supply this member attribute, either directly or through the “input-attributes-default” Printer attribute (section 7.4.6) value.
