QB online; when I try to print the invoice directly it only saves as a PDF. When I used desktop version I could print directly to printer when the invoice was open.

Hi claus-m-sympatic,

Welcome to the Community.  QuickBooks Online is a flexible program that simplifies the way you manage your books. I'd glad to help you with the invoice printing option.

If you're unable to print your invoice from the mobile app, I recommend that you refresh the app to ensure it's up to date. You can refer to the following steps to refresh the app.

For iOS

1. Go to Menu ☰ and tap Help & Feedback and then Refresh Data
2. Tap Refresh to confirm.

For Android

1. Tap More Options from the Menu ☰
2. Select Settings and then Refresh Data
3. Click YES to confirm.

If you're using a browser, I encourage you to clear your browser cache and cookies as they can prevent the system from functioning effectively. You can refer to the following steps to perform browser troubleshooting.
 

• Clear browser cache.

• Make sure you're using supported browsers.
• Turn off any ad and popup blockers temporarily.
