1. Introduction
1.1 Background to Release 3.50
The CEN/XFS Workshop aims to promote a clear and unambiguous specification defining a multi-vendor software
interface to financial peripheral devices. The XFS (eXtensions for Financial Services) specifications are developed
within the CEN (European Committee for Standardization/Information Society Standardization System) Workshop
environment. CEN Workshops aim to arrive at a European consensus on an issue that can be published as a CEN
Workshop Agreement (CWA).
The CEN/XFS Workshop encourages the participation of both banks and vendors in the deliberations required to
create an industry standard. The CEN/XFS Workshop achieves its goals by focused sub-groups working
electronically and meeting quarterly.
Release 3.50 of the XFS specification is based on a C API and is delivered with the continued promise for the
protection of technical investment for existing applications. This release of the specification extends the
functionality and capabilities of the existing devices covered by the specification:
• Addition of E2E security
• PIN Password Entry
1.2 XFS Service-Specific Programming
The service classes are defined by their service-specific commands and the associated data structures, error codes,
messages, etc. These commands are used to request functions that are specific to one or more classes of Service
Providers, but not all of them, and therefore are not included in the common API for basic or administration
functions.
When a service-specific command is common among two or more classes of Service Providers, the syntax of the
command is as similar as possible across all services, since a major objective of XFS is to standardize function
codes and structures for the broadest variety of services. For example, using the WFSExecute function, the
commands to read data from various services are as similar as possible to each other in their syntax and data
structures.
In general, the specific command set for a service class is defined as a superset of the specific capabilities likely to
be provided by the developers of the services of that class; thus any particular device will normally support only a
subset of the defined command set.
There are three cases in which a Service Provider may receive a service-specific command that it does not support:
The requested capability is defined for the class of Service Providers by the XFS specification, the particular vendor
implementation of that service does not support it, and the unsupported capability is not considered to be
fundamental to the service. In this case, the Service Provider returns a successful completion, but does no operation.
An example would be a request from an application to turn on a control indicator on a passbook printer; the Service
Provider recognizes the command, but since the passbook printer it is managing does not include that indicator, the
Service Provider does no operation and returns a successful completion to the application.
The requested capability is defined for the class of Service Providers by the XFS specification, the particular vendor
implementation of that service does not support it, and the unsupported capability is considered to be fundamental
to the service. In this case, a WFS_ERR_UNSUPP_COMMAND error for Execute commands or
WFS_ERR_UNSUPP_CATEGORY error for Info commands is returned to the calling application. An example
would be a request from an application to a cash dispenser to retract items where the dispenser hardware does not
have that capability; the Service Provider recognizes the command but, since the cash dispenser it is managing is
unable to fulfil the request, returns this error.
The requested capability is not defined for the class of Service Providers by the XFS specification. In this case, a
WFS_ERR_INVALID_COMMAND error for Execute commands or WFS_ERR_INVALID_CATEGORY error
for Info commands is returned to the calling application.
This design allows implementation of applications that can be used with a range of services that provide differing
subsets of the functionalities that are defined for their service class. Applications may use the WFSGetInfo and
WFSAsyncGetInfo commands to inquire about the capabilities of the service they are about to use, and modify
their behavior accordingly, or they may use functions and then deal with error returns to make decisions as to how
to use the service.

2. Banking Printers
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

1. Introduction
1.1 Background to Release 3.50
The CEN/XFS Workshop aims to promote a clear and unambiguous specification defining a multi-vendor software
interface to financial peripheral devices. The XFS (eXtensions for Financial Services) specifications are developed
within the CEN (European Committee for Standardization/Information Society Standardization System) Workshop
environment. CEN Workshops aim to arrive at a European consensus on an issue that can be published as a CEN
Workshop Agreement (CWA).
The CEN/XFS Workshop encourages the participation of both banks and vendors in the deliberations required to
create an industry standard. The CEN/XFS Workshop achieves its goals by focused sub-groups working
electronically and meeting quarterly.
Release 3.50 of the XFS specification is based on a C API and is delivered with the continued promise for the
protection of technical investment for existing applications. This release of the specification extends the
functionality and capabilities of the existing devices covered by the specification:
• Addition of E2E security
• PIN Password Entry
1.2 XFS Service-Specific Programming
The service classes are defined by their service-specific commands and the associated data structures, error codes,
messages, etc. These commands are used to request functions that are specific to one or more classes of Service
Providers, but not all of them, and therefore are not included in the common API for basic or administration
functions.
When a service-specific command is common among two or more classes of Service Providers, the syntax of the
command is as similar as possible across all services, since a major objective of XFS is to standardize function
codes and structures for the broadest variety of services. For example, using the WFSExecute function, the
commands to read data from various services are as similar as possible to each other in their syntax and data
structures.
In general, the specific command set for a service class is defined as a superset of the specific capabilities likely to
be provided by the developers of the services of that class; thus any particular device will normally support only a
subset of the defined command set.
There are three cases in which a Service Provider may receive a service-specific command that it does not support:
The requested capability is defined for the class of Service Providers by the XFS specification, the particular vendor
implementation of that service does not support it, and the unsupported capability is not considered to be
fundamental to the service. In this case, the Service Provider returns a successful completion, but does no operation.
An example would be a request from an application to turn on a control indicator on a passbook printer; the Service
Provider recognizes the command, but since the passbook printer it is managing does not include that indicator, the
Service Provider does no operation and returns a successful completion to the application.
The requested capability is defined for the class of Service Providers by the XFS specification, the particular vendor
implementation of that service does not support it, and the unsupported capability is considered to be fundamental
to the service. In this case, a WFS_ERR_UNSUPP_COMMAND error for Execute commands or
WFS_ERR_UNSUPP_CATEGORY error for Info commands is returned to the calling application. An example
would be a request from an application to a cash dispenser to retract items where the dispenser hardware does not
have that capability; the Service Provider recognizes the command but, since the cash dispenser it is managing is
unable to fulfil the request, returns this error.
The requested capability is not defined for the class of Service Providers by the XFS specification. In this case, a
WFS_ERR_INVALID_COMMAND error for Execute commands or WFS_ERR_INVALID_CATEGORY error
for Info commands is returned to the calling application.
This design allows implementation of applications that can be used with a range of services that provide differing
subsets of the functionalities that are defined for their service class. Applications may use the WFSGetInfo and
WFSAsyncGetInfo commands to inquire about the capabilities of the service they are about to use, and modify
their behavior accordingly, or they may use functions and then deal with error returns to make decisions as to how
to use the service.

2. Banking Printers
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 signific
