How to Print to a PDF Printer

Download and install a demo version of Universal Document Converter. When you print a file such as a PowerPoint presentation or AutoCAD design, the converter will appear in your list of printers in the 'Print' dialog box. Select the converter from the list. Universal Document Converter has many features. You can choose what format to print a file to (such as PDF and various image formats), adjust page size and resolution, add a password, crop borders and more. If you tweak with the settings a lot, the program can save your modifications as templates for later use. The demo has no limits except for a large watermark on the lower-right corner of each page.
