Sales Register - printout misses invoices showing on the screen

We use a Sales Register list by date as our service/delivery guide.

We often print these a few days in advance so we can get organised for servicing that customer area.

Before the date more customers may be added and alterations made. Alterations may be made to the invoice for that date if the customer requests changes - the change may be made a few days after.

However, I have found that when I view the Sales Register for a particular day (after that service/invoice date) the screen view has the later adjustments but the printout does not.

There appears to be a disconnect between screen view and printout which is a very serious concern.

Has anyone else experiences this?

How can this be corrected?

Cheers
