How do you print a document came from pdf files?

I am not familiar with PrintShop. But, the generic way to create a PDF file from just about any application on a Mac is:

1) open the document that you wish to convert to a PDF

2) choose File: Print from the menu bar

3) click the PDF button in the lower left-hand corner of the Print dialog

4) choose an option from the menu that meets your needs, such as Save as PDF
