The Bins tab is where you can print barcode labels for bins to be used in Batches. The first panel on the tab will show the printing tasks you've queued (and the quantity of labels for each task), as well as settings for the barcode and label templates. The second panel will show a table of the bin barcodes available. You can add a barcode to the list of printing tasks by toggling the checkbox on that bin's row.
Bin Printing Table
Your bins and their nicknames are laid out in a table. You can add bins to the table, or remove excess bins from the table, by modifying the Number of bins value. You can give each bin a unique nickname by modifying the Nickname value for each bin.
