SetPrinterData info Overview Group

The SetPrinterData function sets the configuration data for a printer.

DWORD SetPrinterData(

HANDLE hPrinter,	// handle of printer object
LPTSTR pValueName,	// address of data type
DWORD Type,	// flag for value type
LPBYTE pData,	// address of array that specifies printer data
DWORD cbData	// size, in bytes, of array
);

Parameters

hPrinter

Identifies the printer for which the configuration data should be set.

pValueName

Points to a null-terminated string that specifies the type of data to be set.

Type

Specifies the type of information to be stored as the value’s data. This parameter can be one of the following values:

Value	Meaning
REG_BINARY	Binary data in any form.
REG_DWORD	A 32-bit number.
REG_DWORD_LITTLE_ENDIAN	A 32-bit number in little-endian format. This is equivalent to REG_DWORD. In little-endian format, a multi-byte value is stored in memory from the lowest byte (the “little end”) to the highest byte. For example, the value 0x12345678 is stored as (0x78 0x56 0x34 0x12) in little-endian format. Windows NT and Windows 95 are designed to run on little-endian computer architectures. A user may connect to computers that have big-endian architectures, such as some UNIX systems.
REG_DWORD_BIG_ENDIAN	A 32-bit number in big-endian format. In big-endian format, a multi-byte value is stored in memory from the highest byte (the “big end”) to the lowest byte. For example, the value 0x12345678 is stored as (0x12 0x34 0x56 0x78) in big-endian format.
REG_EXPAND_SZ	A null-terminated string that contains unexpanded references to environment variables (for example, “%PATH%”). It will be a Unicode or ANSI string depending on whether you use the Unicode or ANSI functions.
REG_LINK	A Unicode symbolic link.
REG_MULTI_SZ	An array of null-terminated strings, terminated by two null characters.
REG_NONE	No defined value type.
REG_RESOURCE_LIST	A device-driver resource list.
REG_SZ	A null-terminated string. It will be a Unicode or ANSI string depending on whether you use the Unicode or ANSI functions.

pData

Points to an array of bytes that contains the printer configuration data.

cbData

Specifies the size, in bytes, of the array.

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value is an error value. To get extended error information, call GetLastError.

The handle hPrinter is obtained by calling the OpenPrinter function.

Existing configuration data for a printer can be retrieved by calling the GetPrinter function.
