Make sure specific invoices aren't selected before printing them, Karen.
Beforehand, can you clarify which section of the invoices page you are referring to regarding the "Do Not Print" option? Any additional details would be much appreciated.
If you're referring to print invoices in batches, please ensure to check the specific invoice transactions and review them before printing. Only those entries marked as checked will appear on the print preview page.
However, if invoices are still being printed even though they're not selected, I recommend clearing your regular browser's cache to remove excessive webpage data.
Otherwise, you can use other supported browsers.
I'm including this reference to help you track and receive customer-paid invoices: Record invoice payments.
