Howard,
Make your own Custom Page size that will be available in any application, including PowerCADD. These are independent of your physical printer(s) and work a treat for printing to PDF files.
1. With a drawing or any document open, select File Menu, Page Setup...
2. Click on the drop down menu Paper Size: and select Manage Custom Sizes... at the bottom of the list
3. In the next window, add a new page size by hitting the "+" button.
4. You can now double-click on the "Untitled" text to name your new size. You also enter the Width, Height and Non-Printable Areas (margins).
5. Hit OK and you're done (or add any other sizes you want).
You will now find this new "paper size" available in all applications. I've added both A0 and A1 to my list and have never had a printer that could print these.
