For busy stores you quite often print all the outstanding invoices or packing slips, pick the orders and then go in to update the status of the orders. This plugin allows you to view and print the invoices or packing slips for all orders with a selected order-status with a single button click.
Once you've installed the plugin, its auto-installer runs the first time someone signs into your Zen Cart admin. To access the plugin, go to your admin's Reports->All Invoices or Reports->All Packing Slips. From that page, use the dropdown to select the order-status value you'd like to display. If any orders exist with the selected order-status, the invoices or packing slips display (in a separate browser tab) onscreen as a continuous list without breaks, but if you print that page each invoice/packing-slip starts printing on a new page.
