A method controls a tape processing apparatus which performs, on a tape to be sent from a tape inlet to a tape outlet along a tape travel passage through an embossing section, a series of tape processing operations of incoming-feed operation to feed the tape from the tape inlet to the embossing section, embossing operation in the embossing section, and of outgoing-feed operation to feed the tape from the embossing section to the tape outlet in an order as mentioned above, and which also indicates in an indicator that the apparatus is in the tape processing operations. The method indicates in the indicator a pre-embossing feed indication to indicate the incoming-feed operation and a post-embossing feed indication to indicate the outgoing-feed operation in an indicating mode which is different from an embossing indication to indicate that the apparatus is in the embossing operation.
