Abstract: A thermosensitive recording material comprising a recording layer formed on a substrate and a coating film layer formed thereon, wherein the recording layer is of a bilayer structure composed of a first thermosensitive layer on the side of the lower layer and a second thermosensitive layer on the side of the upper layer and particles are dispersed in at least one of the first and second thermosensitive layers. An original plate for lithographic printing can be produced from a combination of an ink-philic resin and an ink-repelling resin as the compositional materials of such thermosensitive layers. Besides, thermosensitive, recording materials for magnetic recording, thermosensitive materials for electrostatic recording, thermosensitive recording materials for colored image recording and the like, can be generated through a variety of modifications of the compositional materials.

Abstract: A label printer is disclosed adapted to establish and store therein a set of retrieval codes in which at least one condition of the various conditions of the place where each commodity is kept in stock is encoded and to issue labels in succession for each commodity whose item number satisfies the conditions of the retrieval code, whereby stock control of the commodities is enabled to be easily performed without preparing any special table or the like.

Abstract: A method and apparatus for confirming bar code information in a bar code printer. The information to be printed includes informational digits and two check digits. The first check digit is manually inputted by the operator along with the informational digits. The second check digit is automatically calculated and should have the same value as the first check digit. The data is further confirmed by comparing the first check digit with a calculated value obtained by performing an automatic calculation based on the informational digits.

Abstract: The present invention provides an arrangement wherein a cutting length for a film is included in PLU (price look up) data so that, upon PLU operation, a film can be automatically cut into a sheet having a length suitable to envelope therein an article to be packaged.
