PRINTER_NOTIFY_INFO_DATA info Overview Group

The PRINTER_NOTIFY_INFO_DATA structure identifies a job or printer information field and provides the current data for that field.

The FindNextPrinterChangeNotification function returns a PRINTER_NOTIFY_INFO structure, which contains an array of PRINTER_NOTIFY_INFO_DATA structures.

typedef struct _PRINTER_NOTIFY_INFO_DATA { 

    WORD   Type; 

    WORD   Field; 

    DWORD  Reserved; 

    DWORD  Id; 

    union { 

        DWORD  adwData[2]; 

        struct { 

            DWORD  cbBuf; 

            LPVOID pBuf; 

        } Data; 

    } NotifyData; 

} PRINTER_NOTIFY_INFO_DATA;

Members

Type

Indicates the type of information provided. This member can be one of the following values:

Value	Meaning
PRINTER_NOTIFY_TYPE	Indicates that the Field member specifies a PRINTER_NOTIFY_FIELD_* constant.
JOB_NOTIFY_TYPE	Indicates that the Field member specifies a JOB_NOTIFY_FIELD_* constant.

Field

Indicates the field that changed. For a list of possible values, see the following Remarks section.

Reserved

Reserved.

Id

Indicates the job identifier if the Type member specifies JOB_NOTIFY_TYPE. If the Type member specfies PRINTER_NOTIFY_TYPE, this member is undefined.

NotifyData

A union of data information based on the Type and Field members. For a description of the type of data associated with each field, see the following Remarks section.

The NotifyData union can be one of the following members:

Member	Meaning
adwData	An array of two DWORD values. For information fields that use only a single DWORD, the data is in adwData[0]
Data	The following members are contained in the Data structure:

Member	Meaning
cbBuf	Indicates the size, in bytes, of the buffer pointed to by pBuf.
pBuf	Points to a buffer that contains the field’s current data.

Remarks

If the Type member specifies PRINTER_NOTIFY_TYPE, the Field member can be one of the following values:

PRINTER_NOTIFY_FIELD_PRINT_PROCESSOR
	pBuf points to a null-terminated string that specifies the name of the print processor used by the printer.
PRINTER_NOTIFY_FIELD_PARAMETERS
	pBuf points to a null-terminated string that specifies the default print-processor parameters.

	pBuf points to a null-terminated string that specifies the data type used to record the print job.
PRINTER_NOTIFY_FIELD_SECURITY_DESCRIPTOR
	pBuf points to a SECURITY_DESCRIPTOR structure for the printer. The pointer may be NULL if there is no security descriptor.
PRINTER_NOTIFY_FIELD_ATTRIBUTES
	adwData[0] specifies the printer attributes, which can be one of the following values: PRINTER_ATTRIBUTE_QUEUED PRINTER_ATTRIBUTE_DIRECT PRINTER_ATTRIBUTE_DEFAULT PRINTER_ATTRIBUTE_SHARED

	adwData[0] specifies a priority value that the spooler uses to route print jobs.
PRINTER_NOTIFY_FIELD_DEFAULT_PRIORITY
	adwData[0] specifies the default priority value assigned to each print job.
PRINTER_NOTIFY_FIELD_START_TIME
	adwData[0] specifies the earliest time at which the printer will print a job. (This value is specified in minutes elapsed since 12:00 A.M.)

PRINTER_NOTIFY_FIELD_STATUS
	adwData[0] specifies the printer status. For a list of possible values, see the PRINTER_INFO_2 structure.
PRINTER_NOTIFY_FIELD_CJOBS

	adwData[0] specifies the average number of pages per minute that have been printed on the printer.

If the Type member specifies JOB_NOTIFY_TYPE, the Field member can be one of the following values:

Field	Type of data
