At the 'print label' window, you can print the two sizes item labels. Select the format and set 'print option', then click the 'print' button.
There are 3 print options to select from:
Print for items without vendor barcode only
Print all items that with onhand > 1
Print all items that with onhand = 1
You can also adjust the Horizontal and Vertical offsets if your printer does not print the label in the desired position. A negative value will move the printing area to the left and a positive value will move it to the right.
