Can't print from mobil app..still..makes it useless.

I understand the importance of printing your business needs in QuickBooks Online mobile app, Michelle.

Currently, the mobile app doesn't have the option to print your sales transactions directly. We'll have to preview the form first so it will be opened to your phone's built-in PDF reader.  From there, you have the option to print them. To help improve your experience, I recommend sending feedback directly to our product engineers.

Here's how:

1. Select the Gear icon and choose Feedback.
2. Fill in your suggestions in the Feedback field.
3. Select Next to send it.

Moreover, here's an article on running profit and loss reports using QuickBooks Online mobile app to track your revenue and expenses during a specific period: 

• Run your Profit & Loss report using QuickBooks Online for Android.
• Run a Profit & Loss report using the QuickBooks Online app for iOS.
