The pairing will further enhance the functionality of the host barcode printer. Specifically, the pairing process is initiated when a printer process that requires a handheld printer/scanner device is initiated. The method enables a handheld printer/scanner device to print to a host barcode printer, and also enables the host barcode printer to receive a barcode scan of the case label of received food items and retain information from the barcode scan for future printing of food freshness labels. ## Claims ### Claim 1 A process for pairing a host barcode printer with a handheld printer/scanner device, comprising the steps of: powering on the host barcode printer having at least one antenna and at least one USB device port; starting an application that utilizes device pairing on the host barcode printer; powering on the handheld printer/scanner device; enabling Bluetooth connectivity on both the host barcode printer and the handheld printer/scanner device; enabling connections on the host barcode printer to search for the handheld printer/scanner device; checking to see if an address of the handheld printer/scanner device is found; if the address has been found, then selecting the handheld printer/scanner device to be paired; entering a PIN code; and if the PIN code is valid, then the handheld printer/scanner device is successfully paired and ready to print and the process is exited. ### Claim 2 (depends on 1) The process of claim 1, wherein the application that utilizes device pairing is a receiving process application for food service. ### Claim 3 (depends on 1) The process of claim 1, further comprising: if the Bluetooth connectivity is not enabled, then enabling the Bluetooth connectivity and powering down the handheld printer/scanner device which starts the process over. ### Claim 4 (depends on 1) The process of claim 1, further comprising: if the PIN code is not valid, then prompting the user to re-enter the PIN code. ### Claim 5 (depends on 1) The process of claim 1, further comprising: once the pairing is complete between the host barcode printer and the handheld printer/scanner device, enabling the receiving application to complete receiving operations. ### Claim 6 (depends on 1) The process of claim 1, wherein when a case is received through a receiving door, the handheld printer/scanner device is used to scan a case label. ### Claim 7 (depends on 6) The process of claim 6, wherein the handheld printer/scanner device sends information from the case label back to the host barcode printer which is running the application. ### Claim 8 (depends on 7) The process of claim 7, wherein the application extracts a lot code and a best by date from a barcode on the case label. ### Claim 9 (depends on 8) The process of claim 8, wherein the lot code and best by date are printed on food freshness labels when food items are removed from either cold storage or dry storage. ### Claim 10 A process for pairing a host barcode printer with a handheld printer/scanner device to print a food freshness label, comprising the steps of: powering on the host barcode printer; starting an application that utilizes device pairing on the host barcode printer; powering on the handheld printer/scanner device; enabling Bluetooth connectivity on both the host barcode printer and the handheld printer/scanner device; pairing the host barcode printer and the handheld printer/scanner device; scanning barcode on a case label with the handheld printer/scanner device to extract information that is sent to the host barcode printer; extract a lot code and a best by date from the information received by the host barcode printer using the application; and printing the food freshness label including the lot code and best by date with the host barcode printer.
