Hi KD12,

It's important to me that you can print your invoices as easily as before. It sounds like you're following these steps in your account to complete your task: Sales > Invoices > Select an invoice > More actions > Print packing slip > Print. While replicating this, the print icon on the preview window loaded the invoice in it for me to print, and this should also be the outcome for you. Because this icon is outside of QBO, I'd recommend clearing your cache to ensure there's no bug in your browser or app preventing you from printing. Here's how: Clear cache and cookies to fix issues when using QuickBooks Online

In case the issue persists, I'd suggest checking your PDF reader version as well as your printing settings. Here's an article to assist you with that: How to update, repair, or re-install Adobe Reader/Acrobat

I hope this helps! Feel free to stop by if you need anything else.
