On the print screen after you process shipping labels, a lot of the times I have to break my shipping label prints into a new roll just because there's insufficient funds at the end. Currently, the system does not allow me to add more funds to purchase the remaining labels and it causes a great inconvenience because then I need to reprocess the remaining labels while the other ones are ready to print. I just want one single roll in the end. Not multiple due to the insufficient funds. Please add a button to add more funds on the print screen.
