To hide the new label row, click the green button in the grid header again (item 1 on the image above).
    2. Label image button - click this button to select an image for the barcode label.
    3. Edit button - click this button of a barcode label row to edit it. You can also click in any of the fields of the row to edit it. When ready click the green tick button at the right side of the row to apply the changes or the red "X" button to cancel them.
    4. Delete button - deletes the barcode label row.
  2. Inserting Barcode Duplicates and Sequences
    To insert one or more duplicates of a given barcode label, click it in the grid to select it and then click Insert -> Duplicate. Enter the number of duplicates you want to insert in the dialog that opens and click Insert.

    To insert a barcode sequence click Insert -> Sequence. The "Insert Sequence" dialog will open. You should enter the starting number of the barcode, the increment step and the wanted number of barcodes. If you want enter the prefix and the sufix, too. For example if you enter 12 for prefix, 100 for the initial number (the field "Number") and 341 for suffix, then when you click the Insert button the barcodes 12100341, 12110341, ..., 12250341 will be created. You can see barcodes that are going to be inserted in the preview on the right.
  3. Page and Barcode Settings
    Click the Page button from the toolbar to select page size, page margins and how many rows and columns of barcodes you want on a page. Click the Design button to select the barcode type, the label style and the font sizes for the barcode label. The following label styles are available:
    • Barcode only - barcode labels will have only a barcode and its textual value below it.
    • Barcode and title - barcode labels will have title at the top and a barcode and its textual value below the title.
    • Image, title and text - barcode labels will contain an image on the left, a title on top and a barcode and its textual value below the title.
  4. MegaBarcode Settings
    The Settings button lets you select MegaBarcode's language and measurement units. The selected measurement unit also affects the default page size and the default barcode type. You can select between the following measurement units:
    • Metric units - set the measurement unit to millimeter (mm), the default page size to "A4" and the default barcode type to "EAN-13".
    • US units - set the measurement unit to inch (in), the default page size to "Letter" and the default barcode type to "UPC".
    The default values mentioned above will be set automatically to the new document that is created when you click File -> New. If you want to use different default values, it's best to configure a new document the way you want and save it with File -> Save As to a file, for example "Default.mb". Then each time you want to create a new document instead of clicking File -> New just open your default document via File -> Open.
  5. Generating and Printing the Barcode Labels
    To generate the barcode labels, click the Preview button. MegaBarcode will generate your barcode labels and show them in a new tab of your browser. You can then easily print it by pressing Ctrl + P from the keyboard (Command + P for Mac).
