Abstract

A label printer having a system unit in which price or other such print data is printed on labels. The label printer includes a touch-screen device by which print data setting information to be entered by a hierarchical system of operation screens displayed on the touch-screen may be entered at any desired level in the operating screen hierarchy. Thus, the label printer provides simplified and quick label printout operations by eliminating the need to repeat the input of print data that has already been input. In the label printer of the print data setting information sets the prescribed content of the data to be printed on a label, and print data editing information determines where the data is to be printed on the label and in what format. The print data setting information and the print data editing information are entered by a hierarchy of operating screens displayed in sequence on a touch-screen provided on the label printer system unit. Any desired operation screen in the hierarchy can be displayed on the touch-screen and print data setting information is inputted from that level.

Claims

1. A label printer in which print data is printed on a label, the label printer comprising:

a printer system unit and a touch-screen unit electrically connected to the printer system unit, with print data setting information for setting prescribed content of label print data and print data editing information for printing the print data on the label in a prescribed format being capable of being entered by operating touch screens hierarchically displayed on the touch-screen unit,

data input means displaying print data setting information on a screen of the touch-screen unit and making a data input possible, designation input means designating a treatment address for reading out print data setting information to be displayed subsequent to displaying input data setting information on a screen, display means displaying on a screen a designated print data setting information in accordance with the input from the designation input means;

and an operation screen at any level in the hierarchical structure can be displayed on the touch-screen and print data setting information inputted from that level.

2. A label printer, comprising:

a label printer system unit for generating print data on a label; and

a screen unit electrically connected to the label printer system unit, and for entering print data setting information for prescribing content of the print data, and for entering print data editing information for prescribing format of the print data on the label, data input means displaying print data setting information on a screen of the screen unit and making a data input possible, designation input means designating a treatment address for reading out print data setting information to be displayed subsequent to displaying input data setting information on a screen, display means displaying on a screen a designated print data setting information in accordance with the input from the designation input means, the screen unit adapted for hierarchical display of operating screens with print data setting information capable of being inputted by an operation screen at any level of the hierarchical structure.

3. The label printer according to claim 2 further comprising an interface cable connecting the label printer system unit and the screen unit.

4. The label printer according to claim 2 wherein the screen unit is a touch-screen unit adapted to display touch screens.

5. The label printer according to claim 4 wherein the touch-screen unit includes a liquid crystal display for displaying touch-screens, and a transparent touch-panel in close proximity with a surface of the liquid crystal display, with the operating screen being hierarchically displayed on the liquid crystal display.

6. The label printer according to claim 2 wherein the label printer system unit includes a thermal print head and a platen roller which cooperate to effect printing of print data on a label.

7. The label printer according to claim 2 including an electrical circuit, comprising:

a read-only memory ("ROM") having an operating program which provides overall control of the label printer;

a first memory for storing data;

a second memory;

a video random-access memory ("VRAM");

a printer section;

a central processing unit ("CPU"); and

a bus connecting the ROM, first memory, second memory, VRAM and printer section to the CPU.

8. The label printer according to claim 7 wherein the first memory is a static random-access memory ("SRAM") for storing data, wherein the data is print data, print data parameters, or print data editing parameters.

9. The label printer according to claim 7 wherein the second memory is a dynamic random-access memory ("DRAM").

10. The label printer according to claim 7 wherein the printer section comprises:

a printer head control circuit connected to the bus;

a thermal print head connected to the printer head control circuit;

a stepping motor drive circuit connected to the bus;

a stepping motor connected to the stepping motor drive circuit; and

a platen roller connected to the stepping motor.

11. The label printer according to claim 7 wherein the ROM stores operation screen data and the VRAM generates the operation screen data into operation screen image data.

12. The label printer according to claim 11, further comprising a touch-screen control section connected to the VRAM and the screen unit under the control of the CPU, the operation screen image data is displayed, by the touch screen control section, on the screen unit as sequences of operation screens.

13. The label printer according to claim 7, wherein the first memory has stored therein data field parameter files, each data field parameter file including print data parameters designating print data information, a destination number setting for determining the destination number N that designates a hierarchical level of the operation screen displayed when a next print data is inputted from the screen unit, and print field parameters designating print data editing information.

14. A method of operating a label printer having a printer system unit for printing a label, and a screen unit connected to and for operating the printer system unit, the method comprising the steps of:

operating a data parameter setting screen on the screen unit for setting parameters for printing of a label;

operating a field parameter setting screen on the screen unit for setting print field parameters for printing of a label;

operating a print mode screen on the screen unit;

providing a data input means displaying print data setting information on a screen of the screen unit and making a data input possible;

providing a designation input means designating a treatment address for reading out print data setting information to be displayed subsequent to displaying input data setting information on a screen;

providing display means displaying on a screen a designated print data setting information in accordance with the input from the designation input means, and

printing of one or more labels.

15. A method of operating a label printer having a printer system unit for printing a label, and a screen unit connected to and for operating the printer system unit, the method comprising the steps of:

operating a data parameter setting screen on the screen unit for setting parameters for printing of a label;

operating a field parameter setting screen on the screen unit for setting print field parameters for printing of a label;

operating a print mode screen on the screen unit;

providing a data input means displaying print data setting information on a screen of the screen unit and making a data input possible;

providing a designation input means designating a treatment address for reading out print data setting information to be displayed subsequent to displaying input data setting information on a screen;

providing display means displaying on a screen a designated print data setting information in accordance with the input from the designation input means, and

operating one or more additional screens on the screen unit and at completion of such operation printing one or more labels.

16. The method of claim 15 wherein the screens on the screen unit are operated by touching designated areas of the screens.
