When posting an Inventory Batch, the Post to GL checkbox can be unmarked. This results in the HITB record having a 1900-01-01 00:00:00.000 GL Post Date value ( which would be correct, since it was never posted to the GL side ).

However, if you run HITB for a date prior to the Doc Date, the transaction will show up ( and should not ). It should show up on and after the Doc Date.

So printing by GL Posting Date needs to also consider the Document Date when the GL Posting Date is 'blank'
