Generating A Large Number of Barcodes

Zint Barcode Studio allows to generate a large number of barcodes with sequential values. For that, just select 123.. button.
A new window will appear. Let’s understand this through an example. Let’s say I have to make barcodes for numbers 1-1000.
Then the entries should be as follows.
Start Value = 1
End Value =1000
Increment By  = 1.

Format  = $$$$
Format means, if you give $$$$ 
then the values will be 0001, 0002 ... 1000.
or if you give format as $$$$$, 
then the values will be 00001,00002 ... 01000
Press Create Button. Now You can see all the created barcode numbers on the ‘Sequence Preview’ Box
