The present invention relates generally to the field of label printers, such as those used for food preparation and inventory freshness. More particularly, the present invention relates to a tilting touch screen for a label printer and an improved label printer with such a tilting touch screen.
Restaurants are required to keep track of stored and/or refrigerated food products and ingredients. Label printers are provided in the food preparation/storage area of a restaurant and are used to create “freshness labels” for each package of food or ingredients which specify, among other things, the product/ingredient name, the arrival date and expiration date (and optionally time) for each package. A menu database is created for each class of food items used by a restaurant (sandwiches, salads, drinks, etc.), and the ingredients for each item are provided in the database. The menu database is downloaded to the printer terminal along with parameters for label size, format, expiration dates (or freshness periods), and the like. The label printer may include two print mechanisms, one for printing freshness labels and the other for printing nutritional information, ingredient labels, coupons, receipts, or the like.
Typical prior art label printers used to print freshness labels such as the Avery Dennison Monarch 9415 are expensive, have a large footprint, and provide unfavorable screen angles and features.
It would be advantageous to provide an improved label printer that is cheaper, smaller, easier to use, and easier to maintain than prior art label printers.
The methods and apparatus of the present invention provide the foregoing and other advantages.

The fixed buttons 22 may be conditionally lit from behind by a controlled illumination device 24 (e.g., one or more LEDs or the like), which activates to indicate a certain state or feature of the button 22. A bezel 26 may surround the touch screen overlay 18.
The touch screen 12 may be provided with a configurable layout of buttons in the LCD area 16 (see, e.g.,
Once created, each screen layout is saved in a standard file (e.g., Visio) and downloaded to an SD micro card, which can then be inserted into a corresponding card reader on the printer or LCD controller. Firmware in the printer contains a lookup table which relates the function calls to the desired actions for each button and processes the corresponding screen changes. The following are representative of function calls and corresponding functions or actions that may be provided.
{NULL, NULL,}//end of table marker→End of table marker
In addition to invoking functions, parameters can be defined in Visio and passed to the corresponding function calls/invocations.
Thus, the screen layout is easily customizable by using a standard drawing program to manipulate each screen layout, and downloading the modified file to the printer. Once the screen layout file is downloaded to the printer, certain features of the screen may be further configurable via the touch screen itself, including button size, font selection, font size, and the like.
In addition, as shown in
The touch screen 12 may be adapted to be pivoted or tilted back to provide direct access to the inside of the printer, facilitating paper loading. In other words, the touch screen 12 comprises a cover for the printer housing 40, and opening of this cover gives access to the printer mechanism(s) and corresponding paper bucket(s).
An example of a first embodiment of a label printer 10 with a tilting touch screen 12 in accordance with the present invention is shown in
The print heads, stepper motors, and top of form sensors for the corresponding print mechanisms 34 are also in communication with the controller 42. Each of the touch screen overlay 18, LCD Display 16, controller 42, and print mechanisms 34 are located in the touch screen housing 39.
