SetPrinterDataEx function

The SetPrinterDataEx function sets the configuration data for a printer or print server. The function stores the configuration data under the printer's registry key.

Syntax

DWORD SetPrinterDataEx(
  _In_ HANDLE  hPrinter,
  _In_ LPCTSTR pKeyName,
  _In_ LPCTSTR pValueName,
  _In_ DWORD   Type,
  _In_ LPBYTE  pData,
  _In_ DWORD   cbData
);

Parameters

hPrinter [in]

A handle to the printer or print server for which the function sets configuration data. Use the OpenPrinter, OpenPrinter2, or AddPrinter function to retrieve a printer handle.

pKeyName [in]

A pointer to a null-terminated string that specifies the key containing the value to set. If the specified key or subkeys do not exist, the function creates them.

To store configuration data that can be published in the directory service (DS), specify one of the following predefined registry keys.

Value Meaning
SPLDS_DRIVER_KEY
Printer drivers use this key to store driver properties.
SPLDS_SPOOLER_KEY
Reserved. Used only by the print spooler to store internal spooler properties.
SPLDS_USER_KEY
Applications use this key to store printer properties such as printer asset numbers.

Values that are stored under the SPLDS_USER_KEY key are published in the directory service only if there is a corresponding property in the schema. A domain administrator must create the property if it doesn't already exist. To publish a user-defined property after you use SetPrinterDataEx to add or change a value, call SetPrinter with Level = 7 and with the dwAction member of PRINTER_INFO_7 set to DSPRINT_UPDATE.

You can specify other keys to store non-DS configuration data. Use the backslash ( \ ) character as a delimiter to specify a path that has one or more subkeys.

If hPrinter is a handle to a printer and pKeyName is NULL or an empty string, SetPrinterDataEx returns ERROR_INVALID_PARAMETER.

If hPrinter is a handle to a print server, pKeyName is ignored.

Do not use SPLDS_SPOOLER_KEY. To change the spooler printer properties, use SetPrinter with Level = 2.

pValueName [in]

A pointer to a null-terminated string that identifies the data to set.

For printers, this string specifies the name of a value under the pKeyName key.

For print servers, this string is one of the predefined strings listed in the following Remarks section.

Type [in]

A code indicating the type of data pointed to by the pData parameter. For a list of the possible type codes, see Registry Value Types.

If pKeyName specifies one of the predefined directory service keys, Type must be REG_SZ, REG_MULTI_SZ, REG_DWORD, or REG_BINARY. If REG_BINARY is used, cbData must be equal to 1, and the directory service treats the data as a Boolean value.

pData [in]

A pointer to a buffer that contains the printer configuration data.

cbData [in]

The size, in bytes, of the array.

Return value

If the function succeeds, the return value is ERROR_SUCCESS.

If the function fails, the return value is an error value.

Remarks

Note

This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.

To retrieve existing configuration data for a printer or print spooler, call the GetPrinterDataEx function.

Calling SetPrinterDataEx with the pKeyName parameter set to "PrinterDriverData" is equivalent to calling the SetPrinterData function.

If hPrinter is a handle to a print server, pValueName can specify one of the following predefined values.

Value Comments
SPLREG_ALLOW_USER_MANAGEFORMS Windows XP with Service Pack 2 (SP2) and later
Windows Server 2003 with Service Pack 1 (SP1) and later
SPLREG_BEEP_ENABLED
SPLREG_DEFAULT_SPOOL_DIRECTORY
SPLREG_EVENT_LOG
SPLREG_NET_POPUP Not supported in Windows Server 2003 and later
SPLREG_PORT_THREAD_PRIORITY_DEFAULT
SPLREG_PORT_THREAD_PRIORITY
SPLREG_PRINT_DRIVER_ISOLATION_GROUPS Windows 7 and later
SPLREG_PRINT_DRIVER_ISOLATION_TIME_BEFORE_RECYCLE Windows 7 and later
SPLREG_PRINT_DRIVER_ISOLATION_MAX_OBJECTS_BEFORE_RECYCLE Windows 7 and later
SPLREG_PRINT_DRIVER_ISOLATION_IDLE_TIMEOUT Windows 7 and later
SPLREG_PRINT_DRIVER_ISOLATION_EXECUTION_POLICY Windows 7 and later
SPLREG_PRINT_DRIVER_ISOLATION_OVERRIDE_POLICY Windows 7 and later
SPLREG_RETRY_POPUP On successful return, pData contains 1 if server is set to retry pop-up windows for all jobs, or 0 if server does not retry pop-up windows for all jobs.
Not supported in Windows Server 2003 and later
SPLREG_SCHEDULER_THREAD_PRIORITY
SPLREG_SCHEDULER_THREAD_PRIORITY_DEFAULT
SPLREG_WEBSHAREMGMT Windows Server 2003 and later

Passing one of the following predefined values as pValueName sets the pool printing behavior when an error occurs.

Value Comments
SPLREG_RESTART_JOB_ON_POOL_ERROR The value of pData indicates the time, in seconds, when a job is restarted on another port after an error occurs. This setting is used with SPLREG_RESTART_JOB_ON_POOL_ENABLED.
SPLREG_RESTART_JOB_ON_POOL_ENABLED A nonzero value in pData indicates that SPLREG_RESTART_JOB_ON_POOL_ERROR is enabled.

The time specified in SPLREG_RESTART_JOB_ON_POOL_ERROR is a minimum time. The actual time can be longer, depending on the following port monitor settings, which are registry values under this registry key:

HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors\<MonitorName>\Ports

Call the RegSetValueEx function to set these values.

Port monitor setting Data type Meaning
StatusUpdateEnabled REG_DWORD If a nonzero value, enables the port monitor to update the spooler with the port status.
StatusUpdateInterval REG_DWORD Specifies the interval, in minutes, when the port monitor updates the spooler with the port status.

To ensure that the spooler redirects jobs to the next available printer in the pool (when the print job is not printed within the set time), the port monitor must support SNMP and the network ports in the pool must be configured as "SNMP status enabled." The port monitor that supports SNMP is Standard TCP/IP port monitor.

In Windows 7 and later versions of Windows, print jobs that are sent to a print server are rendered on the client by default. Client-side rendering of print jobs can be configured by setting pKeyName to "PrinterDriverData" and pValueName to the setting value in the following table.

Setting Data type Description
EMFDespoolingSetting REG_DWORD A value of 0, or if this value is not present in the registry, enables the default client-side rendering of print jobs.
A value of 1 disables client-side rendering of print jobs.
ForceClientSideRendering REG_DWORD A value of 0, or if this value is not present in the registry, will cause the print jobs to be rendered on the client. If a print job cannot be rendered on the client, it will be rendered on the server. If a print job cannot be rendered on the server, it will fail.
A value of 1 will render print jobs on the client. If a print job cannot be rendered on the client, it will fail.
