Abstract
A system and method of assuring the proper configuration of a peripheral device to a data processing system so that a job is not commenced unless the proper configuration is established. A unique verification number(s) corresponding to the proper configuration for the job is in the memory of the peripheral device and is available to the data processing system when it corresponds to a current configuration. The verification number(s) for the job is also available to the system from its entry into system resources. Comparison of the verification number(s) for the job from system resources to the verification number(s) indicating current configuration provide assurance of proper peripheral device setup. The invention is exampled for spot color printers used with print servers but applies to any kind of peripheral device. In a second embodiment, verification number(s) for the job from system resources is sent to the peripheral device for establishing its configuration in accordance with the number(s). Necessary alterations of print server software to implement the invention are exampled with reference to the Print Services Facility (PSF) of IBM.
