Description

BACKGROUND

The present invention relates generally to food freshness barcode printers or smart printers acting as a host to a handheld printer/scanner device. More particularly, the present disclosure relates to a process of pairing a handheld printer/scanner device with a barcode printer acting as the host that will enhance the functionality of the host printer.

A barcode printer is a computer peripheral for printing barcode labels or tags that can be attached to, or printed directly on, physical objects. Barcode printers are commonly used to label cartons before shipment, or to label retail items with UPCs or EANs. The most common barcode printers employ one of two different printing technologies. Direct thermal printers use a print head to generate heat that causes a chemical reaction in specially designed paper that turns the paper black. Thermal transfer printers also use heat, but instead of reacting the paper, the heat melts a waxy or resin substance on a ribbon that runs over the label or tag material. The heat transfers ink from the ribbon to the paper.

Barcode printers are designed for different markets. Industrial barcode printers are used in large warehouses, manufacturing facilities, and food facilities. They have large paper capacities, operate faster and have a longer service life. For retail and office environments, desktop barcode printers are most common.

Furthermore, in traditional food preparation and service areas, or other suitable areas, food freshness barcode printers are installed. In these areas, the non-technical user is required to complete tasks such as receiving, breaking down inner packs, putting away ingredients, and maintaining information required for Food Safety. Thus, as the requirements for information supporting supply chain visibility initiatives and Food Service traceability requirements increase, it is desirable to expand the role of a food freshness barcode printer in store to support these goals.

Thus, there exists a need for a food freshness barcode printer or smart printer utilized for printing freshness labels to enhance the operations of a handheld printer/scanner device, such as by enabling the host printer to receive the barcode scan of a case label and retain the information for future label printing use. The present invention discloses a method of pairing the handheld printer/scanner device with a barcode printer acting as a host that will enhance the functionality of the host printer.

The barcode printer 10 comprises a thermal print head (shown in FIGS. 4, 428 and 430) for printing barcodes and alphanumeric information on a web of record members such as tags, labels or the like. The supply of the web of record members may be of the direct printing type such that the record members include paper coated with a thermally responsive material. Alternatively, the supply used with the barcode printer 10 may be of the transfer type wherein a carbon ribbon is heat activated by the print head so as to print on the record members. The print head is strobed to control the amount of energy applied thereto for printing. More particularly, current is applied to the print head during a strobe time in order to print one line on a record member.

The barcode printer 10 also includes a stepper motor (shown in FIGS. 4, 424 and 426) or the like that is responsive to a periodic drive signal, the period of which is defined by the time between the leading edges of consecutive or adjacent pulses of the drive signal. The stepper motor is responsive to the drive signal to advance the web of record members past the print head for printing. The drive signal controls the speed of the stepper motor which in turn controls the print speed of the barcode printer 10.

A controller (shown in FIG. 4, 432) includes a microprocessor 420 or the like which operates in accordance with software routines stored in a memory so as to control the operations of the barcode printer 10. A number of sensors, monitors, detectors or the like such as depicted at 412, 414, 416 and 418 (see FIG. 4), monitor operating conditions of the barcode printer 10 including the resistance of the print head, the contrast setting of the barcode printer, the temperature of a heat sink on which the print head is mounted and the voltage of a battery powering the barcode printer 10. The measured values of the print head resistance, contrast setting, heat sink temperature, battery voltage, as well as other operating variables if desired, are utilized by the microprocessor when implementing print speed control.

Furthermore, the barcode printer 10 would typically be located in the foodservice work area, but could be situated in any suitable area as is known in the art. The barcode printer 10 is a Bluetooth compliant device 20 which further comprises at least one 802.11 a/b/e/g antenna at 21 and at least one USB device port 22, however any suitable number of antenna and USB device ports can be utilized as is known in the art, depending on the wants and needs of a user.

FIG. 3 illustrates a typical layout of a food preparation area for a food service facility where both printers 10 and 210 would be located. As shown in FIG. 3, the receiving door 310 is where both cold and dry storage items are processed. Within the dry storage area, are shelving units 320 for dry storage and a work station 330. At 340, another work station is shown where the food freshness host printer 10 would be located. Cold storage is shown at 360 and swinging doors 370 lead to the customer service area. Further, the handheld portable printer/scanner device 210 is shown at 350. The handheld portable printer/scanner device 210 is paired with the food freshness host printer 10, which allows the handheld portable printer/scanner device 210 to print from the food freshness host printer 10, wherever the food freshness host printer 10 is located within the food service facility.

FIG. 4 illustrates the barcode printer 410 (also shown in FIG. 1 as 10) which comprises a thermal print head 412 for printing barcodes and alphanumeric information. The print head resistance 412 is strobed or heated to control the amount of energy applied thereto for printing. This energy will be varied based upon the heat of the print as determined by the heat sink depicted at 416. The contrast setting, 414, will also impact the length of the strobe. The barcode printer 410 also includes two stepper motors 424 and 426. The stepper motor 424 controlled by MPU 420 advances the web of record members past the print head 428 for printing. In addition, stepper motor 426 controlled by MPU 420 advances the web of record members past the print head 430 for printing.

The barcode printer 410 also includes a controller 432 which includes a microprocessor 420 or the like which operates in accordance with software routines stored in a memory 422 so as to control the operations of the barcode printer 410. The software of the present invention is typically customizable per a user's request which allows the software to be easily tailored around a user's requirement.

A number of sensors, monitors, detectors or the like such as depicted at 412, 414, 416, and 418, monitor operating conditions of the barcode printer 410 including the resistance of the print heads 428 and 430, the contrast setting of the barcode printer, the temperature of the heat sink at 428 and 430 and the voltage of a battery powering the barcode printer 410. The measured values of the print head resistance, contrast setting, heat sink temperature, battery voltage, as well as other operating variables if desired, are utilized by the microprocessor 420 when implementing print speed control.

Furthermore, the barcode printer 410 is a Bluetooth compliant device 436 which further comprises at least one 802.11 a/b/e/g antenna and at least one USB device port. The barcode printer 410 also comprises a user display 434 or monitor.

FIG. 5 illustrates the control board of barcode printer 510 (also shown in FIG. 2 as 210). This control board has minor variances to the control board for printer 410, for example printer 510 contains one printer station instead of two. The printer 510 also comprises a thermal printer head 526 for printing barcodes and alphanumeric information. The printer head 526 is strobed or heated to control the amount of energy applied thereto for printing. This energy will be varied based upon the heat of the print as determined by the heat sink depicted in 526. The contrast setting, 514, will also impact the length of the strobe.

The barcode printer 510 also includes a stepper motor 524. The stepper motor 524 controlled by MPU 520 advances the web of record members past the print head 526 for printing. A controller 534 includes a microprocessor 520 or the like which operates in accordance with software routines stored in a memory 522 so as to control the operations of the barcode printer 510. The software of the present invention is typically customizable per a customer's request which allows the software to be easily tailored around a customer's requirements.

A number of sensors, monitors, detectors or the like such as depicted at 512, 514, 516, and 518, monitor operating conditions of the barcode printer 510 including the resistance of the print head 526, the contrast setting of the barcode printer, the temperature of the heat sink in 526 and the voltage of a battery powering the barcode printer 510. The measured values of the printer head resistance, contrast setting, heat sink temperature, battery voltage, as well as other operating variables if desired, are utilized by the microprocessor 520 when implementing print speed control.

Furthermore, the barcode printer 510 is a Bluetooth compliant device 530 which further comprises at least one 802.11 a/b/e/g antenna and at least one USB device port. The barcode printer 510 also comprises a user display 532 or monitor, and a scanner 528.

An example case label for use with the printers 10 (also 410) and 210 (also 510) is shown in FIG. 6. Handheld printer/scanner device 210 scans the barcode shown at 610 on the label. This barcode is encoded with a unique identification identifying the manufacturer, the item number, the lot number, and the best by date. The lot number is also indicated in the human readable number shown at 620 and the best by date is indicated in the human readable number shown at 630. Handheld printer/scanner device 210 sends this information back to the barcode host printer 10 which is running a specific application. The application extracts the lot number and best by date from barcode 610. This lot number and best by date can then be printed on food freshness labels when food items are removed from either cold storage or dry storage.

However, before the Bluetooth printer can print from the food freshness printer the device must be paired with the printer. FIG. 7 outlines the process required for pairing the devices. At 701, the process is entered. At 705, the printer 10 is powered on and the application selection screen is presented on display 50, the application that utilizes device pairing must then be selected and started. In this case, this application is the receiving process for food service application. At 710, the handheld printer/scanner device 210 is powered on. The user then verifies that the Bluetooth is turned on at 720. If the Bluetooth is not enabled, the Bluetooth is enabled and the handheld printer/scanner device 210 is powered down at 715 and the process returns to 710.

If Bluetooth is enabled, then at 725 a user taps the command CONNECTIONS on printer 10 and searches for the desired handheld printer/scanner device 210. At 730, it is determined if the printer MAC address is found. If no, then at 735 the user taps the “Scan for Devices” tab and the process returns to 730. If yes, then at 740 the desired handheld printer/scanner device 210 (servant printer) is selected to be paired and the PIN code is entered. If the PIN code is valid, then at 745 the desired handheld printer/scanner device 210 is successfully paired and ready to print and the process is exited at 755. If the PIN code is not valid, then at 745 the process returns to 740 for the user to re-enter a correct PIN code.

Once the pairing is complete between barcode host printer 10 and handheld printer/scanner device 210, the receiving application shown in the flow chart in FIG. 8 is enabled to complete the receiving operations. When cases are received through the receiving door, the barcode scanner on the handheld printer/scanner device 210 is used to scan the case label as indicated in FIG. 8. As stated supra, an example case label is shown in FIG. 6. Handheld printer/scanner device 210 sends this information back to barcode host printer 10 which is running a specific application. The application extracts the lot code and best by date from barcode 610. This lot code and best by date can be printed on food freshness labels when food items are removed from either cold storage or dry storage.

As shown in FIG. 8, the receiving process can be completed after the printer 10 and 210 are paired. Entering the process at 800, a user scans the case label at 810 with the handheld printer/scanner device 210. At 820, the scanned data is sent to the barcode host printer 10 where it can be processed by an application program to obtain the Vendor, Item Number, Lot or Serial Number, and Best By date. This data can be used by barcode host printer 10 when printing labels for the transformation step of food prep to identify food items' lot numbers or serial numbers and use by dates.

At 825 the case is opened. The application on host barcode printer 10 will prompt for inner packs at 830. If yes, the process proceeds to 835 to print and apply a received label with the key data elements and a barcode that can be scanned when the item is removed from food storage for food prep. This label has an incrementing count for each inner pack. At 840, the user determines if more inner pack labels are needed and the process continues until the carton is empty. If at 830 there were no inner packs for the carton, then the process continues to 850 where the handheld printer/scanner device 210 prints a received label for the carton containing the key data elements needed for the critical tracking event. Then, both the no branches of 840 and 850 proceed toward putting the item away.

At 845, the need for cold storage is determined by the user or alternately the application program on host barcode printer 10 could contain the proper storage method of the received item. If cold storage is not needed, the process continues to 855 where the inner pack or case is received and then transferred to dry storage at 860. The process then continues to prompt for receiving another case at 885. If yes, then the process returns to 810 and starts over, and if there are no more cases the process exits at 890.

If at 845 it is determined that the user is receiving a cold storage item, the process continues to 865. Then at 870, it is determined if the cold storage item should be stored frozen or under refrigeration. If the cold storage item should be stored frozen, the process continues to 880 and the item is placed in the freezer. If the cold storage item should be stored under refrigeration, the process continues to 875 and the item is placed in the refrigerator. Then, the process continues to 885 to determine if more cases are to be received. If yes, the process continues to 810 and starts over, and if no the process continues to 890 and exits.
