Not to ignore the fancy printer thingamabob, but I can't help but talk coffee. It's my job!

The latte art will come to you if you keep practicing, which is of course a stupid-sounding thing to say, but it's true. Most people find that it doesn't work for them and doesn't work for them and then BAM, suddenly it does. Depending on the technique, of course.

Good luck, and stay away from those printers!
