Thank you for joining this thread, PeakECS.

Let me provide some information about the issue you're experiencing when viewing or printing your sales forms. 

We are aware that certain QuickBooks Online clients are presently experiencing a blank page when printing invoices. Our engineers are working to fix it as soon as possible.

We’ll share updates as soon as we learn more. You may also check for updates on your end from time to time through this link: https://status.quickbooks.intuit.com/.

I appreciate you're patience while we're working on a fix. Have a good one.
