setSendCompleteEventDelegate

Registers a callback method for data transmission completion events.

Syntax

 
 
- (void) setSendCompleteEventDelegate:(id<Epos2LFCSendCompleteDelegate>)delegate;

Parameter

delegate

Specifies an object conforming to the Epos2LFCSendCompleteDelegate protocol.

Protocol declaration

 
 
@protocol Epos2LFCSendCompleteDelegate <NSObject>
@required
- (void) onSendComplete:(Epos2LFCPrinter *)lfcPrinterObj jobNumber:(long)jobNumber code:(int)code status:(Epos2LFCPrinterStatusInfo *)status
@end

Parameter

lfcPrinterObj

The callback source object is stored.

jobNumber

The ID specified by sendLFCData API is stored.

code

The processing result is stored.

Error status

EPOS2_CODE_ERR_UNRECOVERABLE

Unrecoverable error occurred.

EPOS2_CODE_ERR_PORT

Error was detected with the communication port.

EPOS2_CODE_ERR_TIMEOUT

Print timeout occurred.

The printer's buffer is full.

EPOS2_CODE_ERR_BATTERY_LOW

Battery has run out.

status

Status at the timing when the process was run is stored as the Epos2LFCPrinterStatusInfo type.

Supplementary explanation

  • When this API is run multiple times, the callback method specified later takes effect.
  • If nil is specified in delegate when calling this API, the registered callback method is canceled.
  • When controlling multiple printers, compare the caller's LFCPrinter object with the lfcPrinterObj parameter to identify the printer to which the data has been sent.
  • When calling the Epson ePOS SDK API on the method of this API, execute the API in a separate thread.
  • If the disconnect API is called without waiting for a print completion event, the print completion method (setPrintCompleteEventDelegate) may not be notified.
