1. A label forming apparatus comprising: a printing section for performing printing while feeding a processing tape wound into a roll, the processing tape including a tape main body and a release tape, and the printing section including a cutting device for cutting the processing tape and a half cutter for cutting only the tape main body; a working section for performing physical working on the processing tape while feeding the processing tape, the apparatus selectively performing print processing for performing printing, work processing for performing physical working on a piece of the processing tape formed by passing through the printing section, print-and-work processing for performing printing and physical working on the pieces of the processing tape formed by passing through the printing section based on inputted information, and continuous processing for forming a single continuous label in which a plurality of labels are formed in series; a processing selection device for selecting from among the print processing, the work processing, and print-and-work processing; and a control device for controlling the printing section and the working section, wherein the control device allows the continuous processing when the print processing and the work processing are selected, and prohibits the continuous processing when the print-and-work processing is selected, wherein when print-and-work processing is selected, the control device performs individual processing of forming a plurality of labels in succession as individual labels based on prohibition of continuous processing, the control device controls the cutting device to perform cutting of the processing tape at a rear end of the continuous label in continuous processing and to perform cutting of the processing tape at a rear end of each of the labels in individual processing, and the control device controls the half cutter to perform half cutting in which a border of the plurality of respectively adjoining labels is half-cut in continuous processing and prohibit half cutting in the continuous processing of the work processing.
