A virtual printer which includes a document transfer function can be activated within an application program using the standard operating system print mechanism. When the user selects the virtual printer, the software performs the steps of converting the document to a standard display file, requesting a document delivery from a database server, receiving a unique identifier and a name of a file server, uploading the standard display file corresponding to the document, to the named file server, using the unique identifier as the storage identifier, and displaying, in an outbox, an indication that the document was sent. At a remote site, a Document Delivery Service is configured to perform the steps of accepting document delivery requests, initiating such requests, responding with file transfer instructions (including a unique identifier), receiving the uploaded file, storing the file, accepting polling inquiries received from potential document recipients, responding with a list of available documents addressed to each potential recipient, and enabling the recipient computer to download the standard display file. To ensure confidentiality and avoid tampering or forgery, all communication and data transfers between the client computers and the managed file transfer service carried out over secure network connections. |
