Did you make a backup of your TBR data prior to posting? If so, the easiest (and only) thing to do is restore your data prior to posting, which would then have your billing batch ready to print.

There is no history file in TBR than maintains all the bill detail, nor can you restore a bill from history. Thus, if you have posted a billing batch, it cannot be restored to create a new batch (and then print the documents). You really need to have a data backup prior to posting in this situation.

If you don't have a data backup with those 300 bills, I'm afraid you will have to either re-enter the information into a new billing batch to print the bills (and delete the batch rather than post), or hand-write the bills.
