Hi Alberto,

which AutoCAD LT version you are using?
Is it correct that you can print the Layout on printing device, but cannot see PDF saved from the same Layout?
If - yes, than what application do you use for viewing PDF?

If - no, than:
Do you use Preview button in Print window to create PDF file or you are using Batch Publish?
Have you created Page Setup in Page Setup Manager for the Layout you want to save to PDF?
