Can I make a PDF of my calendars, books and other projects? How can I check my work?

dotphoto does not make PDFs of projects, but you can check your projects by previewing them in the product builder, which is the record of your work and an efficient way to check everything on screen. 

If you want to print a record of your work, you could print out preview screens, or you can "print" screen images to PDFs like this:

Right-click on a screen, choose Print, and choose Save as PDF
