YAFPC-Appliance is a CD-ROM image based on KNOPPIX technology and the freeware PDF-Composer/Printer/Mailer YAFPC. Any PC booted from this CD can act as a PDF-Printserver which provides an unlimited number of network shared virtual PDF-Printers. No operating system or other software installation is required. While the system requirements are low, any older PC can be used. System configuration can be done via a Web browser from any workstation in Your network. Virtual shared printers can be configured to apply letterheads, watermarks and appendixes to all printed documents. After printing a document is sent to its owner by mail or can be accessed in a shared folder on the server. Deployment is very simple: Download the image, burn it, boot it, configure the printers.
