To help bypass the problems of only being able to reprint your shipping labels within 24hrs try this. When the screen pops up to print, instead of printing choose the save as pdf feature. This should be towards the bottom of the print pop up in a drop down tab. This will help you keep track of your shipments on your PC as well as allow you to print it wherever and whenever you can.
I've done it that way for 10+ years. Handy in the short term when printer blows up or other problems occur, and in the long term to be able to reference if need be, or for research or curiosity reasons.
