2.2.7 Driver Download Response

The Driver Download Response is a standard HTTP response ([RFC2616] section 6) to the driver download HTTP GET request (section 2.2.6). If the response return code is 200 (success), the response entity body MUST contain the requested driver.

The HTTP redirect is to a URL with Content-Type set to application/octet-stream ([RFC2616] section 7.2.1), which specifies a cabinet file [MSDN-CAB] that has a .webpnp extension. The cabinet file includes the following:

  • Printer driver software files.

  • An INF file [MSDN-INF] that is used during installation of the driver software.

  • A BIN file (section 2.2.7.1) that provides the information needed to access printer setup/configuration data.

  • A DAT file (section 2.2.7.2) that provides additional print server and printer setup/configuration data.
