PS: I've just discovered on online emulator which runs Xfigure in a browser window. (I'm using Firefox on a Windows 7 machine but I'd expect it to work with any setup). You could use that to generate puzzles on a modern PC and then use the Windows Snipping Tool to capture what you see. (Hint: If you're going to be using the Snipping Tool a lot, it makes sense to add it to your computer's taskbar; then you'll only need one click to launch it. To add it to your taskbar, locate it as above, right-click on it and select 'Pin to taskbar').
The only problem you'll encounter doing it that way is that you'll need several screenshots in order to be able to capture all of the clues. (i.e. you need to keep scrolling down between screenshots to ensure that you've got all the clues).
e.g. you need these four captures to get all of the clues for this puzzle:

Once you've got your screen captures, you can paste them into a DTP or word-processing program, as here:

(Click in the middle of the grid to load up th files for it, which takes a few moments. Eventually you'll see a new grid appear. Click within it to lock your cursor to the gameplay. Click 'Esc' to unlock your cursor, so that you can then use the Snipping Tool. Click back in the grid again to scroll down the clues, then click 'Esc' and take another screenshot, etc)
