    QR Code Question

    Derek Hettinger

      Hello there,

       

      I'm a pharmacist in Colorado looking to add a bit of efficiency to our workflow.

      We're using the Zebra handhelds and I'd like to make a QR Code or barcode for special characters:

       

      F3

      Enter

      Up Arrow

      Down Arrow

       

      How would I go about doing this?

          Hello Derek,

           

          With QR code you can print any characters in any encoding using binary mode. In alphanumeric mode it would be an option to print special characters using some prefix character(s) that is(/are) not used in your typical data.  Like that: "\F3", "\ENTER", "\UP", "\DOWN". Or like that: "%F3%", "%ENTER%", and so on. Then you can substitute these values to needed special characters on scan code read stage. To save code space you can use short versions like: "%F3%", "%E%", "%U%", "%D%".

           

          With Code 39 you can print alphanumeric characters and some special characters and control codes. Say there are codes for CR and LF characters that can be used to print Enter. Also there are other special characters. In case they are not used in your data you can use them instead of your special characters to print barcode. Then substitute them to needed special characters on scan code read stage.

           

          Hope it helps.
