Summary:
Until fairly recently, most Web applications employed a client-server architecture in which the browser acted as the client, and a Web or application server performed substantially all processing. This approach is not unlike the old days of "terminal and mainframe," although Web applications are often simpler and easier to use by design. RIAs (Rich Internet Applications) and their HTML/AJAX counterparts change this by downloading software into a Web browser on the client machine, which handles rendering the application's user interface, and communication with the server. This provides the ability for developers to offer "rich" user-interface functionality which is not possible with only HTML and standard browser-based Web applications. The result is the RIA approaches the sophisticated look and feel of desktop software. This, along with the benefits associated with Software as a Service (SaaS) and Web 2.0 applications, has resulted in growing popularity of this development paradigm. Technology giants Adobe and Microsoft are leading the pure RIA charge with their respective Flash (and its Flex development technology) and Silverlight technologies, followed closely by a global cadre of developers, independently and in standards bodies, enhancing HTML and adding AJAX (Asynchronous Javascript and XML) to create such apps without the need to embed proprietary software. With the focus inarguably on the computer screen, and on multi-media applications (think YouTube), little priority has been given by developers to generating hard copy output. At this writing, there is no ability to print application-controlled, formatted content contained in RIAs anywhere but from the desktop computer. The challenge is that all three of the aforementioned technologies can print to a local printer in a rudimentary way, with basic controls, but cannot print with any sophistication from a server. As these technologies gain in popularity, they will contain large volumes of the world's information, much of it suitable and desirable for print output. As individuals and employees in corporations inevitably adopt "Web 2.0 technologies" to replace applications that are today done with desktop software, solutions must be created to enable Rich Internet Printing (RIP). The opportunity is to allow the developer of an Internet application, whether they are using HTML/AJAX, Flash or Silverlight, to print in a graphically rich way, based on standards, from/to the "cloud." One solution would be to create a new kind of "print driver," that uses a standardized way to model the print stream, taking advantage of the richness of the platform it is installed on, but directing the stream out of the app/platform.
