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.
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
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.
