Hi there,@BJZ1718.

I know how convenient it is for you to remove old invoices from the sales window that don't need to print. However, that print queue is already there by default. Even if we unmark Print Later from the invoice, it will still appear on the sales window and the invoice itself. Refer to the screenshot below.

Since it's there by default, it's up to you when to print your invoices. You can print it as many times as you want. If you want to see if an invoice has been printed or not, you can run the Invoice List by Date report. I'll guide you on how.

1. Go to the Reports menu.
2. From the search bar, type Invoice List by Date and click on it.
3. Select the Report period, then Run report.
4. Put a checkmark in the Sales printed box from the gear icon.
