Indesign "Streaming Content" Instead of Printing

Hello all. I have been using InDesign for four years to print booklets. We have always used Canon printers. Last week, we made the switch to HP. Initially, I was able to print my booklets directly in InDesign. Came back from the weekend and cannot get them to print. The one thing I have noticed is on the printing pop-up, where it previously said "Flattening," it now says "Streaming Content." Is there a setting somewhere I missed? The baffling part is that no changes were made over the weekend. I have tried rebooting the printer and re-installing InDesign. Thanks in advance!
