If you are using generic tags without your Company Name and Address pre-printed at the top, you can have Shellstock Tags Software print it for you.
In the Dot Matrix version, go to Setup > Tag Defaults Tab, and in the Laser version go to Setup > Tag Default Options. Fill in both of the address lines there, and click 'OK' (Laser) or 'Save Changes' (Dot Matrix). Your License Company Name and your address lines will now automatically print at the top of each tag.
If you do not want your company name and address to print on the tags, leave both address lines blank.
Note that on the generic tags, there is only room for three lines to print -- the company name and the two address lines.
