This is too late for your problem but since we experienced the exact same issue, I thought I'd post the solution. Like you, we tried everything, including Intuit's QuickBooks Tool Hub. It did not solve the problem.
The problem is that the print system sees the paper size (I believe Windows calls it forms) as a smaller size and chops off the content. Editing the template and changing the print options fixes the problem. Changing the setting back will keep the correct size.
1. Go to an Invoice > Formatting Tab > select Manage Templates
2. Select a common template > OK
3. In the Basic Customization window > Additional Customization > Print Tab
4. For us, the "Use Invoice printer settings from Printer Setup" was selected. Select the other option: "Use specified printer settings below for this invoice". Notice that the paper size is "8 1/2 x 11 in".
5. Click OK to everything to get back to QuickBooks.
6. Verify printing works as expected.
7. Follow steps 1-5 to change the setting back to "Use Invoice printer settings from Printer Setup".
8. Verify printing works as expected.
Cheers!
