Abstract
The invention relates to a bar code label printer including a label sheet feeding unit for feeding a label sheet on which plural labels are adhered to at regular intervals, a printing unit for printing a bar code on the respective labels, a label peeling unit for peeling the printed labels from the label sheet, a sheet drawing unit for drawing the label sheet after the peeling unit, a bar code verifying unit for verifying the bar code printed on the label to detect an ineffective bar code, a re-printing unit for re-printing the same bar code as the ineffective bar code on the next label when the bar code verifying unit detects the ineffective bar code, and an ineffective bar code label remaining unit for remaining the ineffective bar code label on the label sheet without peeling. A bar code label issuing method uses the above described bar code label printer to issue only effective bar code label in an automatically control manner.
