B12.1.2 Multifunction Devices - Industry Standards

Note: This list provides complete titles and web locations for references cited. The listing of a reference here does not imply that complete compliance with that reference is a Windows Logo Program requirement.  

B12.1.2.1 See related industry standards for each device class implemented on the multi-function device

See B1.0 and B2.0.

B12.1.3 Multifunction Devices - Quality

WHQL Test Specification References: Chapter 1: Introduction to HCT Test Specifications Chapter 22: Driver Quality Test Specification Plus technology-specific test specifications

B12.1.3.1 through B12.1.3.4 - See B12.1.4.2
B12.1.3.5 Pass WHQL tests - See B1.3.

See “Multifunction” in the HCT documentation.

B12.1.4 Multifunction Devices - Windows Experience

Design Guideline References: "Designing Multifunction Devices for Windows" at http://www.microsoft.com/hwdev/tech/MF/mfdesign.asp

B12.1.4.1 Separate drivers are required for separate functions with no start order dependencies between separate function drivers

The operating system must be able to configure and manage functions in any order, so no function on a multifunction device can depend on another function to be started before the function can be started by the operating system.

Note that a supervisory driver that loads different drivers for the individual functions does not work well with Windows. In particular, driver support is likely to be lost in cases of operating system re-installation or upgrade, or with distribution of new drivers via Windows Update. Therefore, these supervisory drivers must be avoided.

B12.1.4.2 MFP devices correctly implement driver and Plug and Play support
B12.1.4.2.1 Resource requirements of one functional unit are not expressed in terms of another functional unit.
