What is a WEBPNP file?

A WEBPNP file is a printer driver package file used by Microsoft Windows. It is saved in the .CAB format and contains an install package for a printer driver. WEBPNP files are used for distributing printer drivers provided from websites or client networks.

More Information

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 webpage link (an HTTP request) or a client program requests 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

WEBPNP files are executed by the Windows program wpnpinst.exe which is located in the ~/​Windows/​System32 directory.
