Why would invoice printing and PDF generation fail to work in BUSY even though the options are present?

If invoice printing and PDF generation fail to work in BUSY even though the options are present, you can try the following steps to resolve the issue:
Step 1: Check PDF Viewer Software, Ensure that you have a PDF viewer software installed on your computer, such as Adobe Acrobat Reader. The software needs a PDF viewer to display the invoice preview.
Step 2: Clear Temporary Files, Clear your browser's cache and temporary files. Sometimes, these files can interfere with PDF previews.
Step 3: Update Browser, If you are using a web based version of the software, make sure your web browser is up to date. Outdated browsers can sometimes have issues with PDF rendering.
Step 4: Browser Settings, Check your browser settings for handling PDF files. Ensure it is set to display PDFs using the installed PDF viewer.
Step 5: Reinstall PDF Viewer, If you have a PDF viewer installed, but it's not working correctly, consider uninstalling it and then reinstalling it.
Step 6: Check PDF File Association, Confirm that PDF files are associated with your PDF viewer software. To do this, right click on a PDF file, select Open with, and ensure your PDF viewer is the default program for opening PDFs.
Step 7: Test with Other PDFs, Attempt to open other PDF files from different sources to check if the issue is specific to the software or a broader PDF problem.
Step 8: Update or Reinstall the Accounting Software, Make sure you are using the latest version of BUSY. Software updates often include bug fixes. Check for and install any available updates.
Step 9: Restart Your Computer, Sometimes, simply restarting your computer can resolve issues with PDF previews.
Step 10: Check the printer spooler service in Services.msc for smooth functioning.
If these steps do not resolve the issue, it is recommended to contact BUSY's customer support for further assistance.
