Let's install Microsoft XPS Document Writer on your Windows 11 to ensure you can send your invoices and purchase orders seamlessly, SJ.

Here are the steps to follow:

1. Click on the Windows icon located on the taskbar.
2. Select Settings, then choose Apps from the left sidebar.
3. Click on Optional features, then select Add a feature.
4. In the search bar, enter Microsoft XPS Document Writer.
5. Click the Install button to start the process.
6. Once the installation is complete, confirm that the XPS Document Writer is available by opening the Control Panel.
7. Navigate to Devices and Printers, where you can find Microsoft XPS Document Writer listed as a printer option.

I still recommend contacting Microsoft Support or consulting your IT professional to help you facilitate the installation process, ensuring that you have the necessary features configured correctly.

Moving on, you can personalize your emails to customers and vendors by creating custom templates in QuickBooks Desktop.

After setting everything up, you can begin sending your invoices directly from the program.
