Host Printer Emulation Support on Web-based Client-Server System

Disclosed is a web-based client-server system for enabling host pring emulation support.

This is to be implemented as a three-tier system. The first tier is a legacy host system that sends host print jobs. The second tier is a server that transforms host print data stream into an intermediate format that does not lose format information. Adobe (*) Portable Document Format (PDF) is one of the formats that can be used for that purpose. The last third tier is a client, which uses a standard web browser with an appropriate plug-in program for the intermediate format used in the second tier server. When a host print job is sent, it is transformed into an intermediate format by a server and sent to client and then it is displayed in a web browser. The following figure illustrates how this disclosure is to be implemented using PDF:

Adobe Acrobat PrintoutReader

A existing system is a two tier system that consists of a host and a client, on which a host print emulation program sends host print jobs to a client-attached printer. With this invention, client does not have to have a host print emulation program running and user can browse host print jobs in a web browser without losing format information.
