I understand how the issues with invoicing and printing will impact your business processes, Greg.

Let me share some details about the issue with invoices and printing in QuickBooks Desktop (QBDT).

I'd love to assist you with the invoice issue, but for security reasons, we're unable to check your account here in the Community space. But, if you've already used the QuickBooks Tool Hub but the problem persists, I recommend reaching out to our support team to further investigate and find potential solutions. They have the necessary tools to check your account and initiate a screen-sharing session to review the issue and get a reliable resolution.

Here's how:

1. Click the Help menu.
2. Select QuickBooks Desktop Help/Contact Us.
3. Enter a brief description of your concern, and select Continue.
4. Sign in to your Intuit Account, and select continue.
5. Select chat with us or Have us call you.

For reference, you can check this article: Contact QuickBooks Desktop support.

On the other hand, you can try resetting the temp fold permission to help resolve the print-to-PDF issue after restarting your computer. To do so, follow the steps below:

1. Press the Windows key + R to open the RUN command.
2. Type %TEMP% and press Enter.
3. Right-click an empty area of the temp folder, and select Properties.
4. Select Security.
5. Make sure all user names and groups in Security have Full Control.
6. Once the permissions have been set to Full Control, save it as a PDF again in QuickBooks.

After doing this, check if you can now print to PDF. If the problem persists, test if you can print to your XPS (only for Save as PDF and Email issues) since QuickBooks uses parts of the XPS Document Writer (Microsoft Windows product) to save as a PDF. Here's how:

1. Open Notepad.
2. Type Test. Select File and then Print.
3. Select the XPS Document Writer, and then Print. Note: If you don't see XPS Document Writer, you'll need to allow your computer to print to your XPS printer.
4. Type a filename and save it to your desktop.
5. Go to your desktop and view the XPS document you printed from Notepad.

However, if the issue persists, I recommend working with an IT expert going through steps 3 and 4 in this article to resolve this: Fix PDF and Print problems with QuickBooks Desktop. Also, to help you check and update the printer drivers.
