Scan forms not printing

We've noticed that the past couple days, the USPS Scan Forms are not printing when we "Close Shipping Day", like they normally used to. Upon clicking the button, the site seems to be "thinking" but then nothing else happens, no popup, only a message stating "Close day successful! There were no documents to print". If we go to our Endicia account manually, on the Endicia site, the report show up though, for that currently day.

So apparently, it's generating the scan form, but then not printing or showing it on screen.

Thanks!
