Method and apparatus for printing on a drink

1. A printing device for printing on a current drink comprising:

a. a tray upon which the current drink rests;

b. an ink-jet printer to downwardly ink-jet droplets of ink towards the tray to print an image on the drink supported by the tray;

c. a display-screen;

d. one or more sensor(s) for acquiring current-drink property-data describing the current drink currently supported by the tray;

e. a mapped drink-code database specifying a map for a plurality of drink-printing codes, between:

i. each displayed drink-printing code of the plurality of drink-printing codes; and

ii. a respective combination of (i) a respective drink-printing-code-specific target-image to be printed by the ink-jet printer; and (ii) respective drink-printing-code-specific target-drink property-data describing contents of a respective target-drink and/or its container;

f. analysis circuitry for computing a drink-match parameter between:

i. property-data of the current drink sensed by the sensor(s) and

ii. property-data of one or more of the target drinks specified by the database;

g. a user-interface for:

i. displaying a drink-property-heterogeneous menu comprising the plurality of drink-printing codes on the display-screen; and

ii. receiving a user-selection of one of the drink codes to thereby user-specify, according to the mapped drink-code database, a target-image and target-drink property-data;

h. a device controller for responding to the user drink-code selection, in accordance with content of the mapped drink-code database, output of the sensor(s) and output of the analysis circuitry, by printing the user-interface-specified target-image onto an upper surface of the current drink in a manner that is contingent upon the drink-match parameter that is specific to the combination of:

i. the user-specified target-drink property-data as specified via the user-interface;

ii. the current drink property-data as sensed by the sensor(s).

2. The system of claim 1 wherein the sensor is an image sensor configured to acquire a digital image of an outer wall of a container of the current drink resting on the tray.

3. The system of claim 2 wherein the analysis circuitry is configured to subject the acquired digital image to optical-character-recognition (OCR) analysis derive therefrom the target-drink property-data.

4. A printing device for printing on a current drink comprising:

a. a tray upon which the current drink rests;

b. an ink-jet printer to downwardly ink-jet droplets of ink towards the tray to print an image on the drink supported by the tray;

c. a display-screen;

d. a mapped drink-code database specifying a map for a plurality of drink-printing codes, between:

i. each displayed drink-printing code of the plurality of drink-printing codes; and

ii. a respective combination of (i) a respective drink-printing-code-specific target-image to be printed by the ink-jet printer; and (ii) respective drink-printing-code-specific target-drink property-data describing a contents of respective target-drink and/or its container;

e. a user-interface for:

i. displaying a menu comprising the plurality of drink-printing codes drink-property-heterogeneous on the display-screen such that each drink code is displayed in a manner specific to the respective target-drink property-data associated therewith; and

ii. receiving a user-selection of one of the drink codes to thereby user-specify, according to the mapped drink-code database, a target-image;

f. a device controller for responding to the user drink-code selection, in accordance with content of the mapped drink-code database, output of the sensor(s) and output of the analysis circuitry, by printing the user-interface-specified target-image onto an upper surface of the current drink.

5. A method of providing a customized drink by a plurality of drink-manufacturing machines, each drink-manufacturing machine deployed at a different respective location and including and/or being locally coupled to a different respective display-screen, the method comprising:

a. maintaining, in computer memory, a code-image map between code image-keys and digital graphical images

b. in response to an uploading from a user-terminal, of a digital graphical image or a specification thereof:

A. updating the code-image map to include a mapping between (i) a code-image key specific to the digital graphical image and (ii) uploaded digital graphical image of specification thereof and optionally an identifier of the user-terminal; and

B. sending the code image key to the user terminal;

c. monitoring a location of the user-terminal;

d. in accordance with the results of the monitoring, sending menu-command information to each of the drink-manufacturing machines to regulate the contents of a code-menu on each of the drink-manufacturing-machine-local screens such that:

i. in response to a decrease in a distance between given one of the user terminals and a given one of the drink-manufacturing machines, adding or promoting a code image-key resident in the user terminal to or within a menu of the given one of drink-manufacturing machines; and

ii. in response to an increase in a distance between given one of the user terminals and a given one of the drink-manufacturing machines, removing or demoting a code image-key resident in the user terminal from or within a menu of the given one of drink-manufacturing machines; and

e. for each of the drink manufacturing machines, in response to a user-selection of one of the drink codes, printing on a drink its associated a target-image as defined by the a code-image map.
