Field Details

Station

public int Station

Fiscal Printer error station. This value will be passed to the ErrorStation property in error case during asynchronous processing. Default value: The same station as specified by FiscalReceiptStation.

Level

public int Level

Error level. This value will be passed to the ErrorLevel property in error case during asynchronous processing. Default value: EL_RECOVERABLE.

Constructor Details

OutputRequest

public OutputRequest(FiscalPrinterProperties props)

Constructor. Stores default values for Level and Station for later use.

Parameters:

props - Property set of device service.

Method Details

createErrorEvent

public JposErrorEvent createErrorEvent(jpos.JposException ex)

Error event creator. Level and Station will be taken from this object and State from PrinterState of the property set unless the given exception is a FiscalPrinterException. In the latter case, Level, Station and State will be taken from the exception. OutputID will always be taken from this object.

Overrides:

createErrorEvent in class JposOutputRequest

Parameters:

ex - JposException which is the originator of an error event.

Returns:

FiscalPrinterErrorEvent with values from exception and corresponding

createIdleEvent

public JposStatusUpdateEvent createIdleEvent()

Description copied from class: JposOutputRequest

Factory for status update event with FlagWhenIdle status value. Must be overwritten whenever a device specific status update event shall be created.
If the createErrorEvent method has been overwritten with a method that returns an error event with source = null to enforce special error handling via result properties instead of error events, createIdleEvent must be overwritten as well.

Overrides:

createIdleEvent in class JposOutputRequest

Returns:

The resulting status update event.

invoke

public void invoke()
            throws jpos.JposException

This function should be called whenever a printing method has been invoked. Therefore, it is the perfect place to signal processing has finished to implicitly waiting synchronous methods.

Overrides:

invoke in class JposOutputRequest

Throws:

jpos.JposException - If the invoked method throws an exception.

setIdleWaiter

public static SyncObject setIdleWaiter(JposDevice dev)

Sets SyncObject to be signalled when device becomes idle.

Parameters:

dev - Device to be used.

Returns:

SyncObject to wait for idle, if not idle. null if device is idle.
