The printer comprises a microprocessor (11) for extracting at least two value critical data items from a received stream of open-form data items and for encoding said extracted data items into a coded non-user readable form. The printer is arranged to print said coded data items together with said received data items onto the document. Verification means (31) is provided for reading and decoding said coded data items from the document and for displaying the decoded data items to allow a visual comparison to be made with said printed open-form data items.</p> |
