If you have made changes to products after you created a label job you may be in a scenario where you could be printing out incorrect information. However, Retail alerts you to that fact that the created label information now differs from the current product information:
In the above example you can see that the label job is indicating (grey background with blue text) that on three different products there has been a price change, a PLU change and a description change.
To update this information before printing select F10 Other and then R to refresh the job.
The fields that were showing highlighted with blue characters will then change indicating the new information has been refreshed in the label job.
You can then proceed to print as per normal.
