Just added the ability to print PDF reports to www.therapyhourstracker.com.  I chose to use DOMpdf because it’s free, open-source, and fairly light-weight.  Pretty much the only downside I ran into is that styling the PDF is a real b!t$&.  Theoretically it supports CSS2 selectors and most of the style components but I ended up having to do some really non-standard wrangling to get it to look pretty.  What does it take to get a better option?  Sounds like a couple-thousand dollar license.  I’ll stick with a little extra work, thank you.
