Hi there!
The font will work as long as you proper format it to work. When you are creating the Bitmap (png) file, you need to make sure that every font character is inside of a grid. On your case 32x18 (Height x width). The size of the font will the same as the height of your png file.
The width don't need to be 18. You can even use a width of 50. As long as each character font fits inside a grid alone. The plugin will auto calculate the width of each character to display it properly.
You can take a look at the help file(how to use) on the plugin page, even without purchase the plugin. On the sample project there is also some font examples for you to take a look too.
I don't know if I manage to answer you properly. Let me know if you have any more doubts :)
