Only win7 machine I have is a laptop (sorry I'm a Linux guy). The laptop didn't work because I didn't have the network printer set for the laptop because its a work computer. Once I configured the laptop for the network and set the home printer as default the dropdown box worked (found the printer). I was able to set the path using c:/file path. I set a time for a scheduled print and it worked beautifully. So well, in fact, that with your permission I will continue to use it.
yeah defiantly I'm glad you like it! Enjoy it while you can, and by that I mean i plan to perfect the GUI system better and sell the binaries and keep it opensource AGPL so devs can run it for free/helpdevelop/etc and clients can pay to help continue support
And I'm also a Linux dev, i produced windows binaries because that was the original target system when the idea arose, so with that in mind i will deploy with linux binaries
in the mean time you could download qt creator and then compile/run your self
