Start by adding a unique tag to all customers who require a printed invoice -

Once your customers are tagged, you will now need to create their invoice

Your invoices have been created, now to filter and print.

Select the COLUMNS option to add the TAGS column to your invoice list.

Filter by the unique tag you’ve added to your customers

(Example: For this situation I tagged these customers with ‘PRINT INVOICE’. I then filtered the column for only this specific tag)

After selecting your Tag filter, you can select all or select individual invoices. Click on the 3 dots in the upper right hand corner and Download PDF. This will automatically download any invoices selected to your computer for easy printing.
