When I am printing an invoice the discount line disappears. The discount is still reflected in the total but the line that shows the discount is not there.

Hi there, @a1stove.

Currently, we have an ongoing investigation into the unavailability of the discount section when printing an invoice. Our engineers are working diligently to get this sorted out and provide fixes in no time. Since they are working on this internally, please know that we cannot provide a turnaround time regarding their efforts.

Moreover, I recommend contacting our QuickBooks Support Team to ensure you'll get an update about the resolution status. This way, they can add your company file to the list of affected users and provide this investigation number for easy tracking: INV-103837.
