Class Name PTR
Class Identifier WFS_SERVICE_CLASS_PTR = 1
The WOSA/XFS printer service defines and supports four types of banking printers through a common interface:
· Receipt Printer
The receipt printer is used to print cut sheet documents. It may or may not require insert or eject operations, and often includes an operator identification device, e.g., Teller A and Teller B lights, for shared operation.
· Journal Printer
The journal is a continuous form device used to record a hardcopy audit trail of transactions, and for certain report printing requirements.
· Passbook Printer
The passbook device is physically and functionally the most complex printer. The WOSA/XFS definition supports automatic positioning of the book, as well as read/write capability for an optional integrated magnetic stripe. The implementation also manages the book geometry - i.e. the margins and centrefolds - presenting the simplest possible application interface while delivering the full range of functionality.
· Document Printer
Document printing is similar to receipt printing -- a set of fields are positioned on an inserted sheet of paper -- but the focus is on full-size forms. It should be noted that the WOSA/XFS environment only implements the printing of text fields from the application. The electronic printing of the form image itself is not supported; but can be delivered as an added-value extension by the vendor.
Additional hardware components, like scanners, stripe readers, OCR readers, and stamps, normally attached directly to the printer are also controlled through this interface.
