FAQs & Troubleshooting

Printed barcodes cannot be read.

Try the following:

 

  • Print labels so that barcodes are placed in the direction as shown below:
    OK mark
    NG mark
    OK
    Not Good
    1 Tape feed direction

  • Try using another scanner.
     
  • We recommend printing the barcodes with [Give priority to print quality] selected from the [Quality] options.

    Only the [Give priority to print speed] mode is available when using 2-color printing. (QL-800/810W/820NWB only)

    To display the [Quality] options:
    1. Open the printer properties. (To learn how to open the printer properties, see the FAQ: “How to open the Devices and Printers window”.)
    2. Right-click the printer you want to set up, and then click [Printing preferences].
