Extensions for Financial Services (XFS) interface specification Release 3.30 - Part 3: Printer and Scanning Device Class Interface - Programmer's Reference
This specification describes the functionality of the services provided by banking printers and scanning devices under XFS, focusing on the following areas: • application programming for printing • print document definition • integration with the Windows architecture • scanning images for devices such as check scanners These descriptions include definitions of the service-specific commands that can be issued, using the WFSAsyncExecute, WFSExecute, WFSGetInfo and WFSAsyncGetInfo functions. The requirements for printing in banking applications are significantly different from those of the conventional PC environment, and the XFS support delivers the foundation for financial application printing, including: • Controlled access to shared printers The banking printers can be shared between workstations and the XFS layer provides the ability for the application to manage ownership of a print device. This allows an application to identify the operator granted control of the printer, and to ensure that a teller printing multiple documents is not interrupted by work for other applications. • Application controlled printing In the banking environment, it is necessary for the application to receive positive feedback on the availability of print devices, and the success or failure of individual print operations. The XFS printer support provides a standard mechanism for application retrieval of this status information. • Management of printing peripherals Distributed banking networks require the ability to track the availability and failure of printing peripherals on a branch and system-wide basis. Through the XFS WFSRegister function monitoring programs can collect error alerts from the banking printers. • Vendor independent API and document definition All of the XFS peripheral implementations are designed around a standardized family of APIs to allow application code portability across vendor hardware platforms. With printers, it is also recognized that banks invest a significant amount of resource in the authoring of print documents. The XFS printer service class is implemented around a forms model which also standardizes the basic document definition.
