The bulk of the information about these functions is also available in the Win32 Programmer's Reference. It is presented here in annotated form for ease of reference. The one data structure used by a Network Print Provider that is not described in the Win32 Programmer's Reference is documented in this section also. That is the PRINTPROVIDOR structure.
Other data structures that may possibly be used by the functions in a Windows 95 Network Print Provider are: ADDJOB_INFO_1, JOB_INFO_1, JOB_INFO_2, PRINTER_INFO_1, PRINTER_INFO_2, PRINTER_INFO_3, DRIVER_INFO_1, DRIVER_INFO_2, and PRINTER_DEFAULTS. These data structures used by are used by the Windows NT spooler and have the same definitions in Windows 95. You can find documentation for these structures in the Win32 Programmer's Reference.
