  • Patent number: 5614278
    Abstract: Labels or tags, are generally supplied in the form of a strip of a large number of consecutive, separable units, wherein the components of the labels or tags are essentially fed in a continuous stream to the strip as the strip moves along a path of travel. Under some circumstances however it has been found that it can be cost effective that all of the labels do not include all of the individual components, or that it might not be desirable that the various components are not always disposed at the exact same position in each label.

  • Patent number: 5564210
    Abstract: A price cassette with a back part which has panes to hold interchangeable item identification and/or price labels which are separated by vertical webs, whereby on the back part there are vertical guides, over which the at least partly transparent front part can be slid. The price cassette is thereby curved around an imaginary axis which is horizontal to the item identification and price signs, and the axis of which lies behind the price cassette. The item identification and price information displayed thereby appears more plastic and elegant. The only action required to change this item identification and price information is to open the price cassette partway up or down. The item identification and price signs thereby remain fixed in place.

  • Patent number: 5559547
    Abstract: The invention is directed to a thermal printer, with a thermal print head having a series of electrically drivable heating elements, with a microprocessor transferring data to be printed into a register associated with the thermal print head. In order to increase the printing speed, a buffer storage connected to the microprocessor via a parallel data line as well as a separate load state monitoring circuit are proposed, the monitoring circuit being connected to the buffer storage and causing data to be transferred from the buffer storage into the register when the data written into the buffer storage from the microprocessor has reached a defined quantity. As an alternative or addition, it is recommended to insert a pulse generator and a stepping motor driver between the output of the microprocessor and the stepping motor for driving the platen roll.

  • Patent number: 5553952
    Abstract: A reusable ribbon cassette can be provided for a printer for printing on labels by using an ink transferred from the ribbon to the label material, wherein the ribbon cassette provides the ribbon for the printing. Such a re-usable cassette for a ribbon which is used up rapidly, in particular an ink ribbon in a thermal transfer printing process, has two parallel housing halves, one of which has vertically projecting pins onto which the other housing half can be pushed, and then maintained in position by friction. When the cassette is open, the tape, which is conventionally wound on a tape core, can be pushed onto the cores or core pairs of the cassette, and thereby become simultaneously non-rotationally connected to the cores. The connecting pins for the two housing halves advantageously simultaneously form deflector elements for the tape.
