follow the on screen instructins, sometimes as you go from page to page it might seem kinda slow, just wait on it
when I get to the final page where your "new temporary tag number" is, I will click on "file" the hit "save as", the screen might tell you that it might not "save as" properly, my puter will save it.
by saving this on puter, you can reprint later if you loose temporary tag or if tag gets wet, since it will be printed on plain paper from your printer
