Abstract: A method and system for securely printing postage indicia using a personal computer and a web based browser are provided. A plug-in is utilized to prevent multiple print requests for postage indicia. The plug-in acts as a surrogate print driver and assumes control of the web browser's printing functions. A user accesses a server, via a web browser operating on a host computer, to design a mail piece. The information is assembled by the server in a specific format and returned to the web browser. Upon reading the specific format, the plug-in is activated to organize the information from the server and send it as a print command to a printer coupled to the host computer. Upon completion of the printing, the web browser is automatically directed to another page and the plug-in function is terminated, thereby preventing the printing from being duplicated.
