public class ECLPrintJobEvent

extends ECLEvent

ECLHostPrintSession fires ECLPrintJobEvents to notify interested listeners about a current print job.

There are several event types that correlate to the nature of a print job state change or an error condition occurrence. Some event types contain additional information.

1. Startup

When a ECLHostPrintSession establishes a printer session, it fires an ECLPrintJobEvent of type EHPE_PRINT_JOB_PRINTER_READY.

2. Printing a Job

A print job has three stages: Start, Data, End.

• 2-1. Job Start

  READY: If a printer was opened successfully, ECLHostPrintSession fires a ECLPrintJobEvent of type EHPE_PRINT_JOB_STARTED.

  BUSY: If a busy condition is detected while opening the printer, ECLHostPrintSession will fire an ECLPrintJobEvent. The type is two values ORed together:

  ( EHPE_PRINT_JOB_PRINTER_BUSY | EHPE_PRINT_JOB_PRINTER_INUSE )

  There is no need for a response. When the busy condition is cleared, the print job will be started.

  ERROR: If an error occurred when opening the printer, ECLHostPrintSession will fire an ECLPrintJobEvent of type EHPE_PRINT_JOB_ERROR. The event code can be obtained (getEventCode()). This may contain additional information:

  • EHPE_PRINT_JOB_NO_CODE
  • EHPE_PRINT_JOB_ERROR_PRINTER_NOTFOUND - the specified Windows printer was not found **
  • EHPE_PRINT_JOB_ERROR_PRINTER_NONE_INSTALLED - no Windows printer is installed on the system **
    [** This event type will only be fired for a ECLHostPrintSession having the property-value pair: SESSION_USE_WINDOWS_PRINTER, SESSION_ON]

  See Section 3, Processing an error, for more programming information.

• 2-2. Job Data

  While print job data is being process by the ECLHostPrintSession, one or more ECLPrintJobEvent will be fired. The type is two values ORed together:

  ( EHPE_PRINT_JOB_PRINTER_BUSY | EHPE_PRINT_JOB_STATUS_UPDATE )

  3270 Printer Session: the event code (getEventCode()) represents page number.
  5250 Printer Session: the event code has no meaning.

  This event type contains additional information( getEventExtraInformation()). It is a String that represents the print destination.

  If an error occurs while ECLHostPrintSession is processing print job data, it will fire an ECLHostPrintEvent of type EHPE_PRINT_JOB_ERROR. See Section 3, Processing an error, for more programming information.

• 2-3. Job End

  When ECLHostPrintSession closes the print job, it fires an ECLHostPrintEvent. The type is two values ORed together:

  ( EHPE_PRINT_JOB_COMPLETED | EHPE_PRINT_JOB_READY )

3. Processing an error

When an error occurs, the ECLHostPrintSession fires an ECLHostPrintEvent of type EHPE_PRINT_JOB_ERROR. It then waits for a response that should be sent to it via ECLPS.SendKey(...). There is no timeout while ECLHostPrintSession is waiting for a response.

The following is the list of possible SendKeys(String) responses:

• Cancel Print Job:

  <ECLHostPrintSession>.GetPS().SendKeys(ECLSession.CANCELPJOB_STR)

  When ECLHostPrintSession receives this keystroke, it cancels the outstanding print job and fires an ECLPrintJobEvent. The type is two values ORed together:

  ( EHPE_PRINT_JOB_READY | EHPE_PRINT_JOB_CANCELING )

• Retry Print Job:

  <ECLHostPrintSession>.GetPS().SendKeys(ECLSession.RETRYPRT_STR)

  When ECLHostPrintSession receives this keystroke, it fires an ECLPrintJobEvent of type EHPE_PRINT_JOB_READY in response. The host program should be designed to interpret the sequence EHPE_PRINT_JOB_ERROR--"[retryprint]"---EHPE_PRINT_JOB_READY to mean "send the last print datum again". The host program should then send the record again.

  The timing of the firing of the EHPE_PRINT_JOB_READY event differs slightly according to host type:

  • 3270 :

    If the error condition occurred at the end of a record, i.e. an EOR was already received for that record, ECLHostPrintSession fires the event immediately.

    If the error condition occurred in the middle of a record, the ECLHostPrintSession will wait until receipt of the next EOR before firing the EHPE_PRINT_JOB_READY event..

  • 5250 :

    ECLHostPrintSession fires the event immediately always.

• Continue Print Job:

  <ECLHostPrintSession>.GetPS().SendKeys(ECLSession.CONTINUEPJOB_STR)

  When ECLHostPrintSession receives this keystroke, it ignores the print job error condition and continues to process the print job. No ECLPrintJobEvent is fired in acknowledgement of this keystroke.

4. Termination

When an ECLHostPrintSessio is terminated, no ECLPrintJobEvent is fired.
