BCOEM Auto Label Printer

Web app to automatically check in and print labels for BCOEM using a dedicated label printer

Requirements

Hardware

  • PC running Microsoft Windows (will work on Mac, but label printing is very slow)
  • Dymo 450 or 450XL USB label printer
  • HID compliant laser scanner with Code31 compatibility. Must put CRLF at end of scan output.

Software

Setup

Server

  1. Deploy the NodeJS application with the following environmental variables set:
    • DB_ADDRESS="https://some.mysql.database.com:3306"
    • DB_NAME="mysql_database_name"
    • DB_USERNAME="mysql_database_username_with_write_access"
    • DB_PASSWORD="mysql_database_password_for_username"
    • PASSPHRASE="simple_passphrase_that_is_easy_to_remember
  2. Run index.js to start the server. Databases should be auto-initialized

BCOEM [can be done in advance]

  1. Enter the BCOEM instance base URL
  2. Enter the QR code password.
    • If you have not set up a QR passcode, you can set it up in the BCOEM Admin panel under Competition Preparation -> Competition Info -> QR Code Log On Password
  3. If you are using multiple BCOEM instances, enter the entry prefix. If not, leave it blank.
    • For example, if splitting beers and meads and meads have a "M000001" format on the label, enter M here on the mead BCOEM instance.
  4. Ensure the Instance appears under "Instance Status" as connected.
    • If the instance disconnects after some time, click the circular arrow to attempt to reconnect
    • To remove an instance, click the red "X" button next to it

  1. Download the master list excel template here
  2. Update the list with your competition / BCOEM data
  3. Navigate to the /setup page
  4. Click "Import Entries (.xlsx)"
  5. If you are using multiple BCOEM instances, enter the entry prefix. If not, leave it blank.
    • For example, if splitting beers and meads and meads have a "M000001" format on the label, enter M here on the mead BCOEM instance.
  6. Select your excel file when prompted to upload

System [needs to be done on each check in station machine]

  1. Navigate to the /setup page
  2. Enter the passphrase from step 1 under passphrase
  3. Set a SystemId. Each check in station should have a unique ID.
  4. If desired, set a base counter value.
