Forcing PAHT to send if they did not initially

Hello,

We had to turn the print flag off for a show in order to change 10% of the house to delivery method Will Call. Once those were printed, we turned the print flag back on. Hundreds of PAHT were queued up to go out while the print flag was off. After turning flag on, no PAHT went out.

Has anyone experienced this and found a solution to it?

Thank you.
