Method and apparatus for encoding labels

1. Method of encoding labels with a hand-held portable printer having a hand-held portable housing and a print head capable of printing labels,

wherein a print head and a thermometer that does not physically touch a product are mounted on the hand-held portable housing, the method comprising:

determining an end-of-shelf-life for a product based on a shelf-life controlled by the ingredient with a shortest shelf-life, a temperature, and the nature of the product, and

printing a label with an indication of the end-of-shelf life expectancy.

2. Method of encoding labels with a hand-held portable printer having a hand-held portable housing,

with a thermometer that does not physically touch an item and an on-board microprocessor controller storing shelf-life information of a plurality of perishable items based on initial temperatures,

wherein the print head and thermometer are mounted on the hand-held portable housing, the method comprising:

taking the temperature of a perishable item,

calculating the end-of-shelf-life time and date for the item based on the temperature taken and on a shelf-life controlled by the ingredient with a shortest shelf-life, and

printing a label bearing the end-of-shelf-life time and date.

3. Method of encoding a label with a hand-held portable printer having a hand-held portable housing and a print head capable of printing labels,

wherein a print head and a thermometer that does not physically touch a product are mounted on the hand-held portable housing, the method comprising:

the method comprising:

receiving input regarding an ingredient of a product;

determining the temperature of the product with a the thermometer;

determining an end-of-shelf-life for the product based on a shelf-life controlled by the ingredient with a shortest shelf-life and the temperature; and

printing a label indicating the end-of-shelf-life and/or a bar code.

4. The method of claim 3 , wherein the step of receiving input comprises receiving a selection of an ingredient from a user interface module.

5. The method of claim 3 , wherein the step of receiving input comprises:

scanning a bar code label to obtain bar code data; and

determining ingredients associated with the bar code data.

6. The method of claim 3 , wherein the label includes individual color graphics each representing different days of a week and the printing comprises marking the color graphic that representative the day to which that the end-of-shelf-life corresponds.

7. The method of claim 3 , wherein the step of determining the end-of-shelf-life comprises:

determining an expected shelf-life for the ingredient based on the determined temperature and a look-up table;

determining a current time; and

determining the end-of-shelf-life based on the expected shelf-life and the current time.

8. The method of claim 3 , wherein the step of printing the label is done automatically in response to the determining of the end-of-shelf-life.

9. The method of claim 3 , wherein the step of printing the label including providing an indication of the user causing the label to be printed.

10. The method of claim 3 , wherein the step of receiving input comprises:

scanning a RFID chip to determine the product type; and

determining at least one ingredient associated with the product type.

11. The method of claim 10 , wherein the determining the at least one ingredient comprises wirelessly querying a remote host to obtain information regarding the at least one ingredient.
