.WEBPNP File Extension

Printer driver package file used by Microsoft Windows; saved in the .CAB format and contains an install package for a printer driver; used for distributing printer drivers provided from websites or client networks.

WEBPNP files are often distributed using the Web Point-and-Print Protocol ([MS-WPRN]), which defines a method for downloading print drivers when a user clicks on a Web page link (an HTTP request), or when a client program makes a request for a driver. The website locates the appropriate driver and then returns a WEBPNP file to the requester. Once downloaded, the file can be opened to install the printer drivers.

WEBPNP files may contain the following contents:

• Printer driver and installation files
• An .INF setup file for the installation
• A .BIN file specifying parameters needed to access printer configuration data
• A .DAT file that includes any other printer setup data
