Blank label showing in between desired labels when doing a Print Preview
Check the Template field below. At print time, BarTender will print 1 of every template placed in the document per desired copy, database record, serial, etc. If a template was accidentally added to BarTender, then the effect will be that a blank label is acting like a separator between the desired labels that you want to print.
It is also possible to check if this is the case under the Page Setup menu by going to the Templates tab. Here, you can intentionally add and delete templates as need be in a more user-friendly setup.
