Net Print/400 Browser Plugin


Net Print/400 Browser Configuration

A browser is unable to process all forms of data that are sent from a web server, so browsers are able to be enhanced with the help of plug-ins and helper applications. A plug-in is a platform specific piece of code that is loaded by the browser whenever data of a certain type is accessed. A helper application is a program that is executed to process the data.

General Description

Net Print/400 provides plug-ins (NPnpw32.dll, NetPrintActiveX.dll) and a helper application (Netprint Viewer.exe). The plug-ins are used whenever the data is downloaded using an embed statement, primarily when a print is requested through Webulator/400. The helper application is used for all other cases.

The NETPRTIB program sends the converted spooled file to the browser with special MIME types of "application/x-netprint400" or "application/x-netprint400-ep". Whenever the browser receives a data stream with a MIME type of "application/x-netprint400", it will automatically execute the Net Print/400 helper application. Whenever the browser receives a data stream with a MIME type of "application/x-netprint400-ep", it will automatically execute the Net Print/400 plugin.

When the NETPRTIB program sends HTML output it uses a standard MIME type of "text/html" which the browser handled directly without the help of a plug-in.
