I have been working on ironing out bugs that I have found in handyPrint when running on Yosemite (OSX 10.10). You will find below a link to that new version. It is still possible that bugs are still present. Please report them if you find any

You will also benefit from a new feature that was requested by a few users. v5.0.8 now has the ability to create virtual printers from your physical printers. I call them clone. To create one simply right click the printer name in the handyPrint printer list and select “Create printer copy…”
Then right click the “Copy” printer and select rename:
Rename the printer as you see fit. Then right click that copy and configure as you need. For example you could make that printer a “Landscape” printing configuration.
Enjoy
